How to make Boston Cream Pie Cupcakes
Step 1: Prepare the oven. Preheat it to 350 degrees F or 175 degrees C and with cupcake liners, line a cupcake pan.
Step 2: Cream the butter and sugar in a large mixing bowl for about 3 to 4 minutes until light and fluffy.
Step 3: Stir in the sour cream and vanilla extract until incorporated.
Step 4: In two batches, add the egg whites. Mix well every after each addition until combined, scraping down the sides of the bowl as needed.
Step 5: In a different bowl, mix the dye ingredient. And in a small measuring cup, whisk the milk and butter.
Step 6: To the batter, add half of the dry ingredients, mixing until well incorporated. Add in the milk mixture and mix well.
Step 7: Pour the batter into each cupcake liner and fill it to about halfway through. Place in the preheated oven and bake for about 15 to 17 minutes. Then, do a toothpick test.
Step 8: Take the cupcakes out of the oven and let them cool for at least 2 to 3 minutes before removing them to a cooling rack to cool completely.
Step 9: In the meantime, ready the pastry cream. In a medium-sized bowl, gently beat the egg yolks. Set aside.
Step 10: To a large saucepan, add the sugar, cornstarch, and milk and stir until smooth.
Step 11: Cook the mixture over medium-high heat while stirring continuously until it starts to thicken and bubble.
Step 12: Adjust the heat to medium and simmer for about 2 minutes before removing it from heat.
Step 13: To the egg yolks, whisk a little of the milk mixture before adding the entire egg mixture to the milk mixture
Step 14: Bring the mixture to a light boil for about 2 minutes, stirring continuously.
Step 15: Take the pan out of the heat. Add in the butter and vanilla extract, then stir until smooth. Let the mixture cool to room temperature.
Step 16: Meanwhile, in a large bowl, add the chocolate chips and corn syrup to make the ganache. Pour the heavy cream over the chocolate chips after boiling and allow to sit for at least 3 to 5 minutes before whisking until smooth. Then, place in the fridge for an hour or two to cool and firm.
Step 17: Using a knife or cupcake corer, cut out the centers of the cupcakes. Fill the centres evenly with the pastry cream and top each with the chocolate ganache.
Step 18: Pipe the rose on top beginning in the centre, creating a swirl moving forward. So a cupcake if covered, complete 2 to 3 rotations before releasing the pressure and pulling the piping bag away.
Step 19: Place the cupcakes in the fridge until ready to serve. They are best to consume for up to 2 to 3 days.
