Why You’ll Love This Recipe

This vegan Boston Cream Pie is a fantastic way to enjoy a timeless dessert with a compassionate twist. The cake layers are incredibly soft and tender thanks to a combination of plant-based milk and flaxseed “eggs,” which provide structure and moisture.

The custard filling is made from coconut milk and cornstarch, creating a silky, smooth consistency that perfectly mimics traditional pastry cream without the dairy. And the chocolate ganache is rich and glossy, made from vegan dark chocolate and coconut cream, making it both luscious and dairy-free.

This recipe is not only delicious but also customizable, easy to make, and perfect for sharing at celebrations or simply indulging your sweet tooth. Plus, it’s free of eggs, dairy, and refined sugars if you prefer, making it suitable for a range of dietary preferences.

Ingredients

• For the Cake:
• 1 ¾ cups all-purpose flour
• 1 cup granulated sugar (or coconut sugar for refined sugar-free)
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp salt
• 1 tbsp ground flaxseed mixed with 3 tbsp water (flax egg)
• 1 cup unsweetened almond milk (or other plant milk)
• ½ cup vegetable oil (or melted coconut oil)
• 2 tsp vanilla extract
• 1 tbsp apple cider vinegar
• For the Vegan Custard Filling:
• 1 ½ cups full-fat coconut milk
• ¼ cup cornstarch
• ⅓ cup granulated sugar
• 1 tsp vanilla extract
• Pinch of turmeric (optional, for color)
• For the Chocolate Ganache:
• ½ cup vegan dark chocolate chips
• ⅓ cup canned coconut cream (chilled)
• 1 tsp maple syrup (optional, for sweetness)

Equipment

• Two 8-inch round cake pans
• Mixing bowls
• Whisk
• Measuring cups and spoons
• Electric mixer or hand whisk
• Spatula
• Small saucepan
• Cooling racks
• Offset spatula or butter knife (for frosting)

Instructions

1. Prepare the flax egg: In a small bowl, combine the ground flaxseed with water. Stir and let sit for 5-10 minutes until it thickens.
2. Preheat your oven: Set to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment paper for easy removal.
3. Mix dry ingredients: In a large bowl, sift together the flour, sugar, baking powder, baking soda, and salt.
4. Combine wet ingredients: In a separate bowl, whisk together the almond milk, vegetable oil, vanilla extract, apple cider vinegar, and the flax egg.
5. Make the cake batter: Pour the wet ingredients into the dry and gently fold together until just combined. Avoid overmixing to keep the cake light and airy.
6. Bake the cakes: Divide the batter evenly between the two pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let cool in pans for 10 minutes, then transfer to cooling racks to cool completely.
7. Prepare the custard filling: In a saucepan, whisk together the coconut milk, cornstarch, and sugar until no lumps remain. Heat over medium heat, stirring constantly, until thickened and bubbling. Remove from heat and stir in vanilla extract and turmeric if using. Transfer to a bowl, cover with plastic wrap directly on the surface to prevent skin, and chill until firm.
8. Make the chocolate ganache: Warm the coconut cream in a small saucepan just until hot but not boiling. Pour over the vegan chocolate chips in a heatproof bowl. Let sit 2 minutes, then stir until smooth and glossy. Stir in maple syrup if desired.
9. Assemble the cake: Place one cake layer on a serving plate. Spread the chilled custard evenly over the top. Carefully place the second cake layer on top.
10. Glaze with ganache: Pour the chocolate ganache over the top, letting it drip down the sides. Use an offset spatula to smooth if needed.
11. Chill and serve: Refrigerate the cake for at least 1 hour to set the ganache and custard. Slice and enjoy!

Tips & Variations

“For the best texture, make sure to thoroughly chill your custard filling before assembling the cake. This helps it set nicely and prevents it from oozing out when slicing.”

• Flour alternatives: You can substitute all-purpose flour with gluten-free flour blends if needed. Just be sure to check baking powder and soda content.
• Sweeteners: Swap granulated sugar with coconut sugar, maple syrup, or agave for a different flavor profile and refined sugar-free option.
• Chocolate ganache: Try using vegan semi-sweet chocolate or even a dark chocolate bar chopped into chunks.
• Flavor twists: Add a tablespoon of rum or coffee extract to the custard for a unique depth of flavor.
• Make it mini: Use muffin tins to create individual Boston Cream cupcakes instead of a full cake.
