BOSTON CREAM PIE CUPCAKES

INGREDIENTS

• 6 tbsp (84g), unsalted butter, room temperature (I use
  Challenge Butter)


• 3/4 cups (155g) sugar


• 6 tbsp (86g) sour cream, room temperature


• 2 tsp (10ml) vanilla extract


• 3 large egg whites, room temperature


• 1 1/4 cups (163g) all purpose flour


• 2 tsp (8g) baking powder


• ¼ tsp salt


• 6 tbsp (90ml) milk, room temperature


• 2 tbsp (30ml) water, room temperature

• 2 egg yolks


• 6 tbsp (78g) sugar


• 1 1/2 tbsp cornstarch


• 1 cup + 2 tbsp (270ml) milk


• 1 tbsp (14g) salted butter


• 1 tsp vanilla extract

• 12 oz (338g) semi sweet chocolate chips


• 2 tbsp (30ml) light corn syrup


• 3/4 cup + 2 tbsp (210ml) heavy whipping cream

1. Preheat oven to 350°F (176°C) and prepare a cupcake pan
   with cupcake liners.


2.  In a large mixing bowl, cream butter and sugar together
   until light in color and fluffy, about 3-4 minutes. Do not skimp on the amount
   of creaming time.


3.  Add sour cream and vanilla extract and mix until well
   combined.


4.  Add egg whites in two batches, mixing until well combined
   after each. Scrape down the sides of the bowl as needed to be sure all
   ingredients are well incorporated.


5.  Combine dry ingredients in a separate bowl, then combine
   the milk and water in a small measuring cup.


6.  Add half of the dry ingredients to the batter and mix
   until well combined. Add the milk mixture and mix until well combined. Add
   remaining dry ingredients and mix until well combined. Scrape down the sides of
   the bowl as needed to be sure all ingredients are well incorporated.


7.  Fill the cupcake liners about halfway. Bake for 15-17
   minutes, or until a toothpick inserted comes out with a few crumbs.


8.  Remove cupcakes from oven and allow to cool for 2-3
   minutes, then remove to cooling rack to finish cooling.


9.  While the cupcakes cool, make the pastry cream. Put the
   egg yolks in a medium sized bowl and gently beat them together. Set aside.


10.  Add the sugar, cornstarch and milk to a large saucepan
    and mix until smooth.


11.  Cook, stirring continuously, over medium-high heat until
    mixture begins to thicken and bubble.


12.  Reduce heat to medium and simmer for 2 minutes. Remove
    from heat.


13.  Add a little bit of milk mixture to the egg yolks and
    whisk together, then add egg mixture to milk mixture. This process ensures that
    you don’t cook the egg yolks.


14.  Place the pan back on the heat and bring to a light
    boil. Allow to boil for 2 minutes, stirring continuously.


15. Remove from heat and add butter and vanilla extract.
    Stir until smooth, then set aside to cool to room temperature.


16.  While the cupcakes and cream are cooling, make the
    chocolate ganache. Put the chocolate chips and corn syrup in a large bowl.


17.  Bring the heavy cream to a boil, then pour over the
    chocolate chips. Allow to sit for 3-5 minutes, then whisk until smooth.


18.  Place the chocolate ganache in the fridge until
    completely cool and firm, 1-2 hours.


19.  Once everything is cooled and ready, cut out the centers
    of the cupcakes. I use a cupcake corer, but a knife would work as well.


20.  Divide the pastry cream between the cupcakes and fill in
    the centers.


21.  Top the cupcakes with the chocolate ganache. I used
    Ateco tip 844 (Wilton 2D or 1M would work as well) to pipe roses on top. To
    make the roses, start the piping in the center then create a swirl moving
    outward. Complete 2-3 rotations until the cupcake is covered, then release
    pressure and pull the piping bag away.


22.  Refrigerate cupcakes until ready to serve. Cupcakes are
    best for 2-3 days.
