Vegan Boston Cream Pie Recipe

  • Preheat oven to 350 degrees
  • Prep cake pan with Pam baking spray 


  • 1 box of Duncan Hines White cake mix 
  • 1/3 cup of vegetable oil
  • 3 tablespoons of Bob’s Red Mill Egg Replacer (follow the instructions on pkg. for egg replacement)
  • 1 cup of water


  • 2 tablespoons of Bird’s Custard Powder (available from Amazon)
  • 3 tablespoons of sugar
  • 2 cups of unsweetened cashew milk

Chocolate Topping

  • ½ cup of Enjoy Life Vegan Semi-Sweet chocolate chips
  • 3 tablespoons of Miyoko’s Vegan Butter


Follow the recipe on the box, using Bob’s Red Mill Egg Replacer instead of eggs. Separate cake batter, and place ½ of batter in pan to bake. While the cake is cooling, prepare the custard.


In a pot on the stove (do not turn on the heat yet), mix  Bird’s Custard Powder, sugar, and two tablespoons of the cashew milk. Microwave the rest of the cashew milk for about two minutes. Then turn on the stove to medium-high heat and pour the cashew milk into the pot slowly and continuously stir until the custard becomes thick. Place first part of the cake with the flat side up on cake dish and refrigerate. Also, refrigerate custard (do not put custard on cake warm). 

Wash out the cake pan and dry. Then prep with Pam Baking Spray. Place the remaining batter into the cake pan and bake second part of the cake, which will be the top of the cake. While the top layer of cake is cooling, take out the bottom section of cake from refrigerator and spread about ½ inch of custard on the top leaving 1 inch of border free of custard all the way around. Then place back in the fridge.

When the top of the cake is completely cool, carefully place the top layer of cake on top of custard while matching up the fencing structure. 

Chocolate Topping

Make the chocolate topping by adding the two chocolate topping ingredients to a safe microwave bowl. Microwave for 20 seconds then stir, and repeat another 20 seconds, then 15 seconds. Spread on top.
