Keto Boston Cream Pie: Step-by-Step Guide

Step 1: Prepare the Cake Batter
In a large mixing bowl, combine the 8 large eggs, melted coconut oil, vanilla extract, and allulose. Use an electric mixer to beat the mixture until it’s light and fluffy, about 3-4 minutes.
Step 2: Add Dry Ingredients
In another bowl, whisk together the almond flour and baking powder. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix.
Step 3: Bake the Cake Layers
Preheat your oven to 350°F (175°C). Grease your 9-inch cake pans with cooking spray or coconut oil. 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 the cakes cool in the pans for 10 minutes before transferring them to a cooling rack.
Step 4: Prepare the Keto Custard
While the cakes are cooling, prepare your keto custard according to your favorite recipe. Allow it to cool completely before using.
Step 5: Assemble the Cake
Once the cakes are completely cooled, place one layer on a serving plate. Spread the keto custard evenly over the top. Carefully place the second cake layer on top of the custard.
Step 6: Add the Keto Frosting
Spread the keto frosting over the top layer of the cake, allowing it to drip slightly down the sides for a beautiful finish.
Step 7: Chill and Serve
Refrigerate the assembled Keto Boston Cream Pie for at least 30 minutes to allow the flavors to meld and the pie to set. Slice and serve chilled for the best experience!

Popular Questions
Can I use a different sweetener instead of allulose?
Yes, you can substitute allulose with other keto-friendly sweeteners like erythritol or monk fruit sweetener, but be mindful of the sweetness level as they may vary.
Can I make this dessert dairy-free?
Absolutely! You can use coconut milk or almond milk in your keto custard and a dairy-free chocolate frosting to keep it dairy-free.
