There’s something almost magical about a perfectly executed chocolate cake. The rich aroma that fills your kitchen, the moist crumb that melts in your mouth, and that intense chocolate flavor that satisfies even the most dedicated chocoholics. When I first had to go gluten-free, I feared I’d never experience that perfect chocolate cake moment again. After countless experiments, failures, and finally, sweet success, I’m thrilled to share what I believe is the ultimate gluten-free chocolate cake recipe.
This isn’t just “good for gluten-free” – this is an extraordinary chocolate cake by any standard. Friends and family who’ve tried it often can’t believe it contains no wheat flour. The secret lies in understanding how gluten-free flours work together and maximizing chocolate flavor through a few special techniques.
Why This Gluten-Free Chocolate Cake Works
Before diving into the recipe, let me explain why this particular formula creates such amazing results:
- Balanced flour blend: Rather than relying on a single gluten-free flour, I use a specific combination that mimics the structure conventional flour provides.
- Moisture retention: Gluten-free bakes can dry out quickly, so I’ve incorporated ingredients that lock in moisture.
- Enhanced chocolate flavor: Using both melted chocolate and cocoa powder creates depth of flavor, while coffee amplifies the chocolate notes without making it taste like coffee.
- Perfect texture: The addition of xanthan gum provides the elasticity that gluten normally would, resulting in a cake that holds together beautifully.
Ingredients
For the Cake:
- 1 cup (140g) brown rice flour
- 3/4 cup (84g) almond flour
- 1/2 cup (80g) potato starch (not potato flour)
- 1/4 cup (30g) tapioca starch
- 2 cups (400g) granulated sugar
- 3/4 cup (65g) unsweetened cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon xanthan gum
- 1 teaspoon fine sea salt
- 1/2 cup (113g) unsalted butter, melted
- 4 oz (113g) dark chocolate (70% cacao or higher), melted and cooled
- 2 large eggs, room temperature
- 1 cup (240ml) buttermilk, room temperature
- 1 cup (240ml) hot, strong coffee
- 2 teaspoons pure vanilla extract
- 1 tablespoon apple cider vinegar
For the Chocolate Ganache Frosting:
- 12 oz (340g) semi-sweet chocolate, finely chopped
- 1 1/2 cups (360ml) heavy cream
- 2 tablespoons unsalted butter, room temperature
- 1 teaspoon pure vanilla extract
- Pinch of sea salt
Equipment You’ll Need
- Two 9-inch round cake pans
- Parchment paper
- Mixing bowls (large and medium)
- Electric mixer (stand or hand)
- Measuring cups and spoons
- Rubber spatula
- Wire cooling rack
- Offset spatula (for frosting)
- Cake turntable (optional but helpful)
Detailed Instructions
Step 1: Preparation
- Preheat your oven to 350°F (175°C).
- Grease two 9-inch round cake pans, line the bottoms with parchment paper, then grease the parchment.
- Dust the pans with a little cocoa powder, tapping out any excess.
- Brew a cup of strong coffee and keep it hot.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together:
- Brown rice flour
- Almond flour
- Potato starch
- Tapioca starch
- Sugar
- Cocoa powder
- Baking soda
- Xanthan gum
- Salt
Make sure to break up any lumps, especially in the cocoa powder. The uniform distribution of these dry ingredients is crucial for an evenly textured cake.
Step 3: Prepare Wet Ingredients
- Melt the butter and set aside to cool slightly.
- Melt the dark chocolate in the microwave in 30-second intervals, stirring between each, or use a double boiler. Allow to cool slightly.
- In a medium bowl, whisk together:
- Melted butter
- Melted chocolate
- Eggs
- Buttermilk
- Vanilla extract
- Apple cider vinegar
Step 4: Combine and Bake
- Pour the wet ingredients into the dry ingredients and mix on low speed until just combined.
- Slowly add the hot coffee while mixing on low speed. The batter will be quite thin – this is normal and creates the moist texture we’re aiming for.
- Divide the batter evenly between the prepared pans.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
- Allow the cakes to cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.
Step 5: Make the Ganache Frosting
- Place finely chopped chocolate in a heatproof bowl.
- Heat the heavy cream in a saucepan until it just begins to simmer (small bubbles form around the edges) – do not boil.
- Pour the hot cream over the chocolate and let it sit undisturbed for 2 minutes.
- Gently stir until smooth and glossy.
- Add the room temperature butter, vanilla extract, and salt, stirring until completely incorporated.
- Allow the ganache to cool and thicken at room temperature, stirring occasionally, until it reaches a spreadable consistency (about 30-45 minutes). You can refrigerate it to speed up this process, but check and stir it every 5-10 minutes.
Step 6: Assemble and Frost
- Once the cakes are completely cool, place one layer on a serving plate or cake board.
- Spread about 1 cup of ganache evenly over the first layer.
- Place the second layer on top.
- Apply a thin “crumb coat” of ganache all over the cake and refrigerate for 15 minutes.
- Apply the remaining ganache, creating decorative swirls if desired.
Pro Tips for the Perfect Gluten-Free Chocolate Cake
- Room temperature ingredients matter: Cold eggs or buttermilk can cause the melted chocolate to seize.
- Don’t overmix: Once you add the dry ingredients, mix just until combined to avoid a dense texture.
- Check your oven temperature: An oven thermometer can ensure you’re baking at the right temperature.
- Cool completely: Attempting to frost a warm cake will lead to melted, runny frosting.
- Don’t skip the coffee: It enhances the chocolate flavor without making the cake taste like coffee. If you must avoid caffeine, decaf works just as well.
- Weigh your ingredients: For the most consistent results, use a kitchen scale instead of measuring cups.
Storing and Freezing
Short-term Storage:
The cake will stay fresh at room temperature, covered, for up to 2 days. For longer freshness, refrigerate for up to 5 days. Just be sure to bring it to room temperature before serving for the best flavor and texture.
Freezing:
This cake freezes beautifully! You can freeze it frosted or unfrosted:
- Unfrosted layers: Wrap each layer tightly in plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before frosting.
- Frosted cake: Place the cake in the freezer uncovered for 1 hour to set the frosting. Then wrap in plastic wrap followed by aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator, then bring to room temperature before serving.
Variations to Try
Flavor Twists:
- Mocha: Add 1 tablespoon instant espresso powder to the batter.
- Raspberry: Add a layer of raspberry preserves between the cake layers.
- Orange: Add the zest of one orange to the batter for a chocolate-orange cake.
- Mint: Add 1/2 teaspoon peppermint extract to the ganache.
Frosting Alternatives:
- Whipped ganache: Allow the ganache to cool completely, then whip with an electric mixer until light and fluffy.
- Buttercream: A classic American or Swiss meringue buttercream works wonderfully too.
- Simple dusting: Skip the frosting entirely and just dust with powdered sugar for a more casual dessert.

Troubleshooting Common Issues
Cake Sinks in the Middle:
- Possible cause: Opening the oven door too early or underbaking.
- Solution: Avoid opening the oven during the first 25 minutes of baking and make sure to bake until a toothpick comes out with just a few moist crumbs.
Cake is Too Dense:
- Possible cause: Overmixing the batter or inaccurate measurements.
- Solution: Mix just until ingredients are combined and consider weighing ingredients for precision.
Cake is Dry:
- Possible cause: Overbaking or incorrect flour ratio.
- Solution: Watch baking time carefully and follow the flour measurements exactly.
Ganache is Too Runny:
- Possible cause: Incorrect chocolate-to-cream ratio or not enough cooling time.
- Solution: Allow more time for the ganache to cool and thicken, or refrigerate it in 10-minute intervals, stirring between each.
Q&A Section
Q: Can I use a pre-made gluten-free flour blend instead of the individual flours? Yes, you can substitute 2½ cups of a good quality all-purpose gluten-free flour blend for the rice flour, almond flour, potato starch, and tapioca starch. Make sure your blend contains xanthan gum, or add it separately as directed in the recipe.
Q: Why is coffee included in this recipe? Coffee enhances the flavor of chocolate without making the cake taste like coffee. The hot liquid also helps bloom the cocoa powder, intensifying its flavor.
Q: Is this cake dairy-free? No, this recipe contains butter, buttermilk, and heavy cream. However, you can make it dairy-free by substituting:
- Vegan butter for regular butter
- Non-dairy milk + 1 tablespoon lemon juice for buttermilk
- Full-fat coconut milk for heavy cream
Q: Can this recipe be made as cupcakes? Absolutely! Fill cupcake liners about 2/3 full and bake at the same temperature for about 18-22 minutes. This recipe should yield approximately 24 cupcakes.
Q: Why do you add apple cider vinegar to the batter? The vinegar reacts with the baking soda, creating bubbles that help the cake rise and achieve a lighter texture – especially important in gluten-free baking.
Q: How can I tell when the cake is done baking? Insert a toothpick into the center of the cake. It should come out with a few moist crumbs attached, but not wet batter. The cake should also spring back slightly when touched.
Q: Can I make this cake in advance for a special occasion? Yes! You can bake the layers up to 2 days in advance and store them wrapped in plastic at room temperature. You can also make the complete frosted cake 1 day ahead and store it in the refrigerator. Just bring it to room temperature before serving.
Q: What makes this cake stay moist when many gluten-free cakes are dry? The combination of melted chocolate, buttermilk, and hot coffee adds moisture, while the specific ratio of gluten-free flours helps retain that moisture.
