Ingredients

For the Cake

2 cups (240g) gluten-free flour blend (with xanthan gum)
¾ cup (75g) unsweetened cocoa powder
1¾ cups (350g) granulated sugar
2 tsp baking soda
1 tsp baking powder
1 tsp fine sea salt
2 large eggs, room temperature
1 cup (240ml) buttermilk, room temperature
1 cup (240ml) hot strong coffee (or hot water)
½ cup (120ml) neutral oil (vegetable or avocado)
2 tsp pure vanilla extract

For the Chocolate Buttercream

1 cup (225g) unsalted butter, softened
½ cup (50g) unsweetened cocoa powder
3 cups (360g) powdered sugar, sifted
3–4 tbsp heavy cream
1 tsp pure vanilla extract
Pinch of salt

Instructions

Step 1 — Prep Your Pans

Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper. Grease the parchment too.

Step 2 — Mix the Dry Ingredients

In a large bowl, sift together the gluten-free flour, cocoa powder, sugar, baking soda, baking powder, and salt. Whisk until fully combined.

Step 3 — Add the Wet Ingredients

Make a well in the center of the dry ingredients. Add the eggs, buttermilk, oil, and vanilla. Whisk until just combined — a few small lumps are fine. Then carefully pour in the hot coffee and stir until the batter is smooth. The batter will be thin — that’s normal!

Step 4 — Bake

Divide the batter evenly between the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs (not wet batter). Do not overbake.

Step 5 — Cool Completely

Let the cakes cool in the pans for 15 minutes, then carefully turn out onto a wire rack. Allow to cool completely before frosting — at least 1 hour.

Step 6 — Make the Buttercream

Beat the softened butter with a hand mixer until pale and fluffy, about 3 minutes. Add cocoa powder and mix on low. Gradually add powdered sugar, 1 cup at a time. Add cream, vanilla, and salt. Beat on high for 2 minutes until light and fluffy.

Step 7 — Frost & Serve

Place one cake layer on a serving plate. Spread about ½ cup frosting over the top. Place the second layer on top and frost the top and sides. Decorate as desired. Slice and serve!

Pro Tips for the Perfect Gluten-Free Chocolate Cake

Use room temperature ingredients — cold eggs and buttermilk cause uneven mixing.
Don’t skip the hot coffee — it deepens the chocolate flavor without making the cake taste like coffee. Hot water works too.
Check your flour blend — make sure it contains xanthan gum, which gives structure to gluten-free baked goods.
Don’t overmix — mix just until the flour disappears or your cake can turn dense.
Cool completely before frosting — otherwise the buttercream will melt right off.
