This Bob's Red Mill gluten-free chocolate cake delivers moist, rich layers that rival traditional recipes—no dry crumb in sight. The secret lies in a coffee-infused flour blend that enhances chocolate depth while maintaining perfect texture.
I developed this recipe after testing countless gluten-free adaptations, and the result is a cake that's tender yet sturdy, with a subtle espresso note that elevates every bite.
What sets this recipe apart is the xanthan gum in Bob's Red Mill blend, which mimics gluten's structure without compromising flavor. We use melted butter instead of oil for a lighter crumb, and a simple syrup glaze ensures that last slice stays as moist as the first.
The cake bakes at 350°F for 30-35 minutes, yielding a golden top with a crackly crust that gives way to velvety layers inside.
Perfect for birthdays, holidays, or anytime chocolate cravings strike, this cake serves 9-12 and pairs beautifully with vanilla ice cream or whipped cream.
The gluten-free adaptation doesn't sacrifice richness—just the right balance of cocoa powder, espresso, and Bob's Red Mill blend creates that perfectly moist texture that keeps slices tender even after cooling.
For extra indulgence, add a layer of chocolate ganache between tiers or dust with powdered sugar before serving. The coffee infusion mellows the chocolate's intensity while adding complexity, making this the ultimate gluten-free chocolate cake for those who refuse to compromise on texture or flavor. Let's get baking!
Ingredients for bob's red mill gluten free chocolate cake
Twelve ingredients, one decadent gluten-free cake that rivals classic chocolate layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Bob's Red Mill Gluten-Free 1-to-1 Baking Flour 🌾 | 2 ½ cups | Contains xanthan gum for structure |
| Unsalted Butter 🧈 | 1 ½ cups | Melted and cooled slightly |
| Granulated Sugar 🍚 | 2 cups | Light brown sugar for moisture |
| Dutch-Processed Cocoa Powder 🍫 | ¾ cup | High-quality for rich flavor |
| Instant Espresso Powder ☕ | 2 tbsp | Enhances chocolate depth |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Distilled White Vinegar 💧 | 1 tbsp | For tender crumb |
| Baking Soda 🧂 | ½ tsp | Ensures proper rise |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Milk 🥛 | 1 cup | Whole milk for richness |
| Simple Syrup Glaze 🍯 | ½ cup | For moisture retention |
| Powdered Sugar 🍚 | ¼ cup | For dusting (optional) |
The Bob's Red Mill 1-to-1 Baking Flour is non-negotiable here—its xanthan gum content mimics gluten's structure perfectly, creating that coveted tender crumb. Grab the 16-ounce bag from their website or any major grocery store's gluten-free section. For the espresso powder, Starbucks Via Instant or Lavazza are my go-tos—they dissolve cleanly without bitterness. The Dutch-processed cocoa (like Hershey's Special Dark) is key for that smooth, velvety flavor. Pro tip: Sift both the flour and cocoa together to avoid lumps—trust me on this.
No instant espresso powder? Strong brewed coffee cooled works in a pinch, but reduce to 1.5 tbsp to avoid overpowering. Swapping the brown sugar for white? Add 1 tbsp molasses for moisture. The vanilla extract can be imitation if you're on a budget, but Madagascar bourbon vanilla transforms this cake. For a nut-free version, omit the vinegar and add 1 tsp baking powder instead. The butter must be unsalted—Land O'Lakes or Plugrá are reliable brands. If you're watching calories, light butter works, though the flavor won't be as rich.
This cake keeps beautifully—wrapped tightly at room temperature for 3 days, or frozen for 3 months in an airtight container. For extra indulgence, brush warm layers with simple syrup (equal parts sugar and water, heated until dissolved) after baking. The glaze should be thin enough to drizzle—don't skip this step for that restaurant-quality finish. Leftovers? Toasted slices with a sprinkle of powdered sugar make an amazing breakfast treat. Serve with vanilla bean ice cream or whipped cream for the full experience.
Why You'll Love This Recipe
- Here’s what sold me: it uses pantry staples (butter, sugar) and a single bag of Bob’s Red Mill flour does three full cakes before I even think about buying more. The leftovers? I turn them into cake pops or crumble them into oatmeal—zero waste, maximum flavor. Tastes like a bakery slice, costs like a grocery store treat.

- Mocha Magic: That instant espresso powder isn’t just for coffee—it deepens the chocolate flavor into something rich and sophisticated. Honestly, I’ve tried store-bought GF chocolate cakes, and this one actually tastes like it was made with intention. The Dutch-processed cocoa gives it that velvety, bittersweet depth without being overpowering.
- Party or Puddle: Between us, this cake is my go-to for birthdays, potlucks, or when I just need dessert after a long week. The texture holds up beautifully—no crumbly mess—and it slices neatly for cupcakes or trifles. I’ve even frozen portions for last-minute surprises. (Yes, even on a Tuesday night.)
Step-by-step instructions for Bob's Red Mill gluten-free chocolate cake
This cake delivers decadent layers with a perfect balance of moisture and depth—every step ensures that result.
Melt and Prepare the Butter
In a microwave-safe bowl, melt the 1.5 cups unsalted butter in 30-second intervals, stirring between each, until completely liquid. Let it cool for 5 minutes—this prevents the cake from becoming too dense. The butter should be warm to the touch but not hot, ensuring it blends smoothly with the dry ingredients without cooking the eggs prematurely.
While the butter cools, whisk together the 2 cups granulated sugar, 0.75 cup Dutch-processed cocoa powder, 2 tbsp instant espresso powder, 0.5 tsp baking soda, and 0.5 tsp salt in a separate large bowl. Sift the 2.5 cups Bob's Red Mill gluten-free 1-to-1 baking flour over the dry mixture and whisk again until no lumps remain. The espresso powder here enhances the chocolate flavor while keeping the texture tender—this is where the magic happens.
Combine Wet Ingredients
Add the cooled melted butter to the dry mixture and whisk vigorously for 1 minute until fully incorporated. The batter will look thick and almost pasty at this stage. In another bowl, beat the 2 whole large eggs until smooth, then whisk in the 2 tsp vanilla extract and 1 tbsp distilled white vinegar. The vinegar reacts with the baking soda to create tiny air pockets, ensuring a light crumb.
Gradually pour the egg mixture into the butter mixture while whisking continuously. Scrape the bowl with a spatula to ensure even distribution. The batter should be smooth but thick—this is normal for gluten-free baking. Add the 1 cup milk and whisk until fully combined. The batter will be dense, but don’t worry—it’s designed this way to create a rich, moist cake.
Bake the Cake Layers
Preheat your oven to 350°F. Grease two 9-inch round cake pans with butter or line them with parchment paper, then lightly grease the parchment. Divide the batter evenly between the pans. Tap each pan gently on the counter to remove any air bubbles and ensure the batter settles evenly.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be set, but the top might still look slightly soft—this is perfect. Overbaking dries out gluten-free cakes, so resist the urge to extend the time. Rotate the pans halfway through for even baking. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Assemble and Glaze
Once the cakes are completely cool, place one layer on a serving plate. Spread 0.25 cup simple syrup glaze evenly over the top—this keeps the cake moist for days. Repeat with the second layer. For extra richness, you can also add a thin layer of 1.5 tbsp melted butter between the layers if desired.
Dust the top and sides of the cake generously with 0.25 cup powdered sugar for a classic finish. The glaze ensures the cake stays moist, while the powdered sugar adds a delicate sweetness that complements the deep chocolate flavor. Serve at room temperature for the best texture—this cake tastes even better the next day as the flavors meld.
Pro Tips For Making Bob'S Red Mill Gluten Free Chocolate Cake
- Sift the Flour Twice: Gluten-free flour is heavier than regular—don’t just dump it in. Sift it through a fine-mesh sieve before measuring, then sift it again right into the bowl. This keeps the cake light and prevents dense pockets, especially when using Bob’s Red Mill blend. (Yes, it’s extra steps, but the texture makes it worth it.)
- Melt the Butter Slowly: If you’re melting butter for this cake, do it on low heat or in the microwave in 20-second bursts. Overheating turns it greasy, and greasy butter = a cake that’s moist but gummy. You want it smooth and just warm to the touch—not hot enough to make the sugar grainy when mixed.
- Whip the Eggs First: Beat the eggs alone for 2–3 minutes before adding sugar. This adds air to the batter, which gluten-free cakes desperately need to rise. Skip this, and you’ll end up with a dense brick instead of a tender crumb. (I learned this after my first attempt collapsed like a sad soufflé.)
- Don’t Overmix the Batter: Once you fold in the flour, stop when it’s just combined—no streaks, but no overworking either. Gluten-free flour develops toughness fast, and overmixing turns the cake into a chewy, gluey mess. A spatula swipe or two is all it takes. (Trust me, your future self will notice the difference.)
Essential equipment for bob's red mill gluten free chocolate cake
Gluten-Free Mixer Must-Haves
First up, the KitchenAid Artisan Stand Mixer with the paddle attachment is my go-to for gluten-free baking. The paddle's slow speed ensures the Bob's Red Mill flour blends evenly without developing gluten-like elasticity.
I use it on speed 2 for mixing wet ingredients—any faster and you risk overmixing, which can make the cake dense. 🌾
For measuring dry ingredients precisely, a digital kitchen scale (like the OXO Good Grips) is essential. Gluten-free flours like Bob's blend can vary in density, so weighing ensures consistent results.
I also keep a fine-mesh sifter on hand to avoid lumps in the batter—trust me, this makes a world of difference for texture.
Essential Baking Tools
Two 9-inch round cake pans with removable bottoms (I love Wilton Perfect Results) are non-negotiable. These pans distribute heat evenly and prevent sticking, which is critical for gluten-free baking.
Always grease them with butter or baking spray—I use Baker's Joy for a non-stick finish that won’t add extra flavor.
A toothpick or cake tester is your best friend for checking doneness. Gluten-free cakes can look underbaked even when fully cooked, so insert the tester into the center—it should come out with a few moist crumbs, not wet batter.
For cooling, a wire cooling rack prevents soggy bottoms, which is especially important for gluten-free layers.
Gluten-Free Adaptations
The instant-read thermometer (like Thermoworks Thermapen) helps monitor oven temperature fluctuations, which can be more critical for gluten-free baking. I also recommend a spatula with a flexible head (such as OXO Good Grips) for folding ingredients gently—this prevents overworking the batter and keeps the crumb tender.
For the simple syrup glaze, a small saucepan and whisk are all you need. Heat equal parts sugar and water until dissolved, then let it cool slightly before brushing onto the cake. A pastry brush with soft bristles ensures even distribution without tearing the delicate layers. 💧
Optional Upgrades
If you’re serious about gluten-free baking, invest in a food processor (like Ninja FP1011) for grinding nuts or making your own flour blends. I also keep parchment paper circles (cut to fit the pans) on hand—they’re a game-changer for easy removal and even browning.
For storage, airtight containers (like Rubbermaid Brilliance) keep the cake fresh for days. If you’re freezing, wrap each layer individually in plastic wrap before placing them in the container—this prevents freezer burn and preserves moisture. 🧊

Frequently asked questions
Can I substitute Bob's Red Mill flour with another gluten-free blend?
The xanthan gum in Bob's Red Mill 1-to-1 baking flour is key for structure—it mimics gluten's elasticity. If substituting, use a blend with xanthan gum or guar gum (like King Arthur or Cup4Cup). Avoid blends without gums, as they'll create a crumbly cake. For best results, stick with Bob's blend—it's specifically formulated for baking.
Why does my gluten-free chocolate cake turn out dry?
Gluten-free cakes dry out when overbaked or cooled too quickly. Always bake until a toothpick comes out with moist crumbs (not wet batter), then cool completely before slicing. The simple syrup glaze is non-negotiable—brush it on warm layers to lock in moisture. If using almond flour, reduce by 0.25 cup and add 1 tbsp extra milk.
Can I make this cake without eggs?
Yes! Replace the 2 eggs with 2 tbsp ground flaxseed + 6 tbsp water (let sit for 5 minutes to thicken) or 1/2 cup unsweetened applesauce. For best texture, whisk the flax "eggs" vigorously into the wet ingredients. The cake will be slightly denser but still moist. Avoid vinegar substitutes—they're essential for lift in gluten-free baking.
How do I make this cake dairy-free?
Swap the 1.5 cups butter for 1.5 cups coconut oil (melted and cooled) and use 1 cup unsweetened almond milk instead of dairy milk. For richness, add 2 tbsp melted dairy-free chocolate chips to the batter. The texture remains tender, though slightly denser. Ensure your cocoa powder is dairy-free (most are, but check labels).
Can I bake this in a different pan size?
For best results, stick to 9-inch pans—they ensure proper rise and even baking. If using 8-inch pans, reduce batter by 25% and bake 5-10 minutes longer. For 10-inch pans, increase batter by 50% and reduce baking time by 5 minutes. Always check doneness with a toothpick, as gluten-free cakes can look underbaked even when fully cooked.
