Ingredients
Scale
Pastry Cream
- 2 cups whole milk
- 1 tablespoon vanilla bean paste
- 4 large egg yolks
- 1/2 cup caster/superfine sugar
- 1/4 cup cornstarch
- 2 tablespoons unsalted butter (cubed)
Cake
- 1 cup plain gluten free flour blend
- 1/2 cup almond flour
- 1/2 cup caster/superfine sugar
- 1 tablespoon baking powder
- 1 teaspoon xanthan gum
- 1/2 teaspoon salt
- 1/2 cup unsalted butter (softened)
- 1 large egg
- 1/2 cup whole milk (room temperature)
- 1 tablespoon vanilla bean paste
Chocolate Ganache
- 4 ounces dark chocolate (chopped)
- 1 cup double/heavy cream
Instructions
- Preparation: Preheat your oven to 350ºF (180ºC). Prepare two 6-inch round cake tins by greasing or lining them with parchment paper.
- Heat Milk and Vanilla: In a saucepan, cook the 2 cups of whole milk and 1 tablespoon vanilla bean paste over medium-high heat until it begins to boil.
- Whisk Egg Yolks and Sugar: In a mixing bowl, whisk 4 large egg yolks and 1/2 cup caster sugar until pale and smooth. Stir in 1/4 cup cornstarch to combine well.
- Temper Egg Mixture: Slowly pour the hot milk into the egg-sugar blend while whisking continuously to prevent curdling.
- Cook Pastry Cream: Return the combined mixture to the saucepan and cook over high heat, whisking constantly for 1-2 minutes until thickened and smooth.
- Add Butter: Remove from heat and stir in 2 tablespoons cubed unsalted butter until melted and fully incorporated.
- Cool Pastry Cream: Transfer the pastry cream to a bowl, cover with cling film touching the surface to prevent skin forming, and set aside to cool completely.
- Mix Dry Ingredients: In a large bowl, sift together 1 cup gluten-free flour blend, 1/2 cup almond flour, 1/2 cup caster sugar, 1 tablespoon baking powder, 1 teaspoon xanthan gum, and 1/2 teaspoon salt.
- Incorporate Butter: Work the softened 1/2 cup unsalted butter into the dry ingredients using fingers or a pastry cutter until the mixture resembles fine breadcrumbs.
- Combine Wet Ingredients: In a separate bowl, whisk together 1 large egg, 1/2 cup room temperature whole milk, and 1 tablespoon vanilla bean paste.
- Make Batter: Gradually add the wet mixture to the dry ingredients, stirring until the batter is smooth and homogeneous.
- Fill Cake Pans: Divide the batter evenly between the two prepared cake tins and smooth out the tops.
- Bake Cakes: Bake in the preheated oven for 22-24 minutes until well risen, golden, and a toothpick inserted into the center comes out clean.
- Cool Cakes: Let the cakes cool in their tins for about 10 minutes, then transfer to a wire rack to cool completely.
- Assemble Layers: If needed, level the cakes to create a flat surface. Place one sponge on a cake stand or serving plate.
- Spread Pastry Cream: Whisk the cooled pastry cream to smooth it out and spread evenly over the bottom sponge layer.
- Add Second Sponge: Gently place the second sponge on top and press down slightly to adhere.
- Prepare Ganache: Place the chopped 4 ounces dark chocolate in a heat-proof bowl. Heat 1 cup double cream in a saucepan until it just begins to boil, then pour it over the chocolate.
- Mix Ganache: Stir until smooth and glossy, then allow the ganache to cool and thicken, stirring occasionally to prevent setting too firm.
- Top the Cake: Pour or spoon the ganache over the top sponge, smoothing it out for a beautiful glossy finish.
Notes
- Ensure the pastry cream is cooled completely before assembling to prevent melting the cake layers.
- Using xanthan gum in the cake batter helps provide structure and elasticity typical in gluten-free baked goods.
- Let the ganache cool enough to thicken before pouring to avoid it running off the sides of the cake.
- Store the Boston Cream Pie in the refrigerator and consume within 2-3 days for best freshness.
- Room temperature ingredients help create a smoother batter and more even bake.
