Ingredients
For the Gluten-Free Sponge Cake:
- 1 cup gluten-free all-purpose flour (with xanthan gum included)
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- 4 large eggs, separated
- ¾ cup granulated sugar, divided
- ½ cup milk (or dairy-free alternative)
- ¼ cup vegetable oil
- 1 tsp vanilla extract
For the Custard Filling:
- 2 cups milk
- ½ cup granulated sugar
- 3 tbsp cornstarch
- 4 large egg yolks
- 2 tsp vanilla extract
- 2 tbsp butter
For the Chocolate Ganache:
- ½ cup heavy cream (or coconut cream for dairy-free)
- ½ cup dark chocolate chips
Instructions
Step 1 — Prepare the Sponge Cake
- Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
- In a medium bowl, whisk together gluten-free flour, baking powder, baking soda, and salt.
- In a separate bowl, beat egg yolks with ½ cup sugar until pale and creamy. Add milk, oil, and vanilla extract. Mix well.
- Gradually fold in the flour mixture until smooth.
- In another bowl, beat egg whites until soft peaks form, then gradually add the remaining ¼ cup sugar, beating until stiff peaks form.
- Gently fold the egg whites into the batter to keep it light and airy.
- Divide batter evenly between the two pans. Bake for 20–25 minutes, or until a toothpick inserted comes out clean. Allow cakes to cool completely.
Step 2 — Make the Custard Filling
- In a saucepan, combine milk and half of the sugar. Heat until warm but not boiling.
- In a separate bowl, whisk egg yolks with remaining sugar and cornstarch until smooth.
- Slowly pour the warm milk into the egg mixture, whisking constantly.
- Return the mixture to the saucepan and cook over medium heat, stirring continuously, until thickened.
- Remove from heat, stir in butter and vanilla. Cover with plastic wrap directly on the surface to prevent a skin from forming. Cool to room temperature.
Step 3 — Prepare the Chocolate Ganache
- Heat cream in a small saucepan until just simmering.
- Pour over chocolate chips in a heatproof bowl. Let sit for 1–2 minutes, then stir until smooth. Cool slightly before pouring over the cake.
Step 4 — Assemble the Boston Cream Pie
- Place one sponge layer on a serving plate. Spread the custard evenly over the top.
- Top with the second sponge layer.
- Pour chocolate ganache over the top, letting it drip slightly down the sides.
- Chill for 1–2 hours to set before slicing.
Tips for Gluten-Free Success
- Flour choice: Use a high-quality gluten-free all-purpose flour blend with xanthan gum included for best texture.
- Light sponge: Gently fold in egg whites to keep the cake fluffy.
- Custard consistency: Stir constantly while cooking to avoid lumps or burning.
- Chocolate finish: Let ganache cool slightly before pouring to prevent it from melting the custard.
Variations
- Dairy-free version: Use almond or oat milk and coconut cream for the ganache.
- Flavor twist: Add a teaspoon of espresso powder to the ganache for a mocha flavor.
- Mini version: Make cupcakes with custard-filled centers and chocolate tops for individual servings.
Storage
- Store in the refrigerator for up to 3 days.
- Cover with plastic wrap to prevent the cake from drying out.
- Best served chilled or at room temperature.
