Boston Cream Pie

Who thinks we've had enough healthy stuff around here??

Me too!!

It's time for some cake!

I know the title says pie...but apparently Boston Cream Pie is actually a cake.

The only Boston Cream Pie I've ever seen was my mom's donuts. LOL!

Seriously, my mom love Boston Cream donuts and that's all I've ever known...until now.

The Cake Slice Bakers voted this as the cake for February.

It seems like a lot. There are 3 components to this cake. But they are all pretty straight forward and not too difficult.

The cake itself was a bit on the dry side for my taste, but it was a darn good cake nonetheless. And my mom thoroughly enjoyed it!

Let's get baking!

Let's start with the custard filling. Whisk sugar, cornstarch, and egg yolks together.

Add in some of the warm milk.

Pour the egg mixture back into the pan. Whisk and cook until thickened.

Remove from heat and whisk in butter.

Strain the mixture through a fine mesh sieve.

Stir in some vanilla.

Cover in plastic wrap and chill. Do you love my red plastic wrap???

Now let's make the cake. Whisk together some cake flour, salt, and baking powder.

Heat up some milk and butter.

Whisk up some eggs.

Gradually add some sugar...

And some vanilla. Keep whisking until tripled in volume and mixture becomes pale.

In 3 additions, gently fold in the flour mixture.

Reheat the milk then add it all at once to the batter.

Pour the batter into your prepared pan and bake.

Go ahead and make the glaze while the cake is cooling. Heat some cream, add the chocolate until melted and smooth, add the vanilla, cover, and cool.

Now let's put the cake together. Whisk together the chilled custard and heavy cream.

Slice the cake into 2 even layers. Fill with the custard and top with the glaze.

Serve and enjoy!!

  2. In a medium mixing bowl, whisk together the cake flour, baking powder, and salt. Set aside.
  3. In a small saucepan, over medium heat, cook milk and butter just until butter is melted. Remove from heat and set aside.
  4. In the bowl of an electric mixer, using the whisk attachment, whisk eggs at high speed until blended, about 1 minute.

  6. Gently fold 1/3 of the flour mixture into the egg mixture. In 2 more additions, repeat with the remaining flour mixture.

  5. Let cool for about 10 minutes.
To Assemble the Cake
  1. Using a long serrated knife, cut the cake into 2 even layers.
  2. Place custard filling into the bowl of an electric mixer. Add the 1/4 cup heavy cream and whisk at high speed until mixture is light and soft peak forms, about 1 minute.
  3. Reserve smooth bottom portion of the cake for the top. Place the other layer of the cake, cut side up, on a platter. Spread custard filling over this cake layer. Top with remaining cake layer.
  4. Pour warm glaze over the top of the cake, allowing the glaze to flow over the edges of the cake. 
  5. Serve immediately or refrigerate.
  6. Enjoy!!
