These Mini Gluten-Free Boston Cream Pies Recipe (2024)

For the Cakes

• 175 grams or 1¼ cups gluten-free cake flour (143g high-quality all-purpose gluten-free flour + 4 tablespoons (32g) cornstarch)*
• ½ teaspoon xanthan gum omit if your blend already contains it
• ½ teaspoon baking powder
• ¼ teaspoon baking soda
• ¼ teaspoon kosher salt
• 109 grams, or ½ cup packed light brown sugar
• 28 grams, or 2 TBSP unsalted butter, melted and cooled
• 24 grams, or 2 TBSP vegetable shortening, melted and cooled
• 1 extra-large egg at room temperature beaten
• 1 teaspoon vanilla bean paste or replace with equal volume pure vanilla extract
• ½ cup plus 2 TBSP buttermilk

For the pastry cream

• 30 grams, or ¼ cup cornstarch
• 150 grams, or ¾ cup divided
• 2 cups milk I don’t drink milk, so I almost always use almond milk , divided
• 4 egg yolks
• 1 teaspoon vanilla bean paste
• 2 tablespoon butter
• pinch of salt

Chocolate Glaze

• 130 grams, 4.5 oz bittersweet chocolate, roughly chopped
• 60 grams, or 4 TBSP butter
• 1 tablespoon corn syrup

• Preheat your oven to 325 degrees F and grease a mini whoopie pie pan.

• In a large bowl, place the flour, xanthan gum, baking powder, baking soda and salt and whisk to combine well.

• Whisk in the brown sugar, making sure you remove any lumps.

• Next, mix in the butter, shortening, egg and vanilla and make sure everything is well combined.

• Now, add the buttermilk, and mix again to combine well. You will have a batter that is somewhere between cake batter and cookie dough in consistency.

• Using a small scoop or you can pipe about as much as a large marble to each well of your whoopie pie pan.

• Bake on a center rack for 8-10 minutes, or until the cakes bounce back when pressed gently in the center. Remove from the oven and allow to cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Repeat with the remaining batter.

Make the pastry cream

• Prepare an ice bath.

• In a small mixing bowl, combine ¼ cup sugar, egg yolks and the creamer (or ½ cup milk).

• In a medium sauce pan over medium heat, bring the remaining 1½ cups milk to a boil, stirring constantly.

• Remove from heat and add the hot milk to the egg mixture about a third at a time to temper the eggs. If you do this too fast you will end up with scrambled egg yolks and not a smooth cream.

• Return the pot to the stove and add the egg mixture. Over medium heat, keep whisking until the cream thickens and when you scrape the bottom of a pot, the cream does not close the gap immediately. Stir in the vanilla, salt and butter.

• Put the pot over your ice bath and stir every 5-10 mintues for about half an hour, or until the cream has cooled.

Make the glaze

• When you are ready to assemble the mini boston cream pies, melt together the chocolate, butter and corn syrup over low heat. If the mixture is not pourable, add an extra tablespoon of butter.

Assemble the cakes

• Pipe the pastry cream onto half of the cake pieces. Take one of the other cake pieces and top each one. Pour or spread chocolate glaze on each mini Boston cream pie.
