But recently…I’ve fallen head over heels for these amazing Boston Cream Cupcakes. I seriously cannot get enough of them. I find myself wanting to make them for any and all occasions to share them with everyone that I know. Truth be told, they’re so good, they’re almost addictive!

How many other times do you get the chance to eat a cupcake that is moist, full of goodness and has a super delicious chocolate topping as well? It’s true that all cupcakes are quite yummy, but these Boston Cream Cupcakes are totally over the top. (and in a good way!)

Don’t just take my word for it. Try a batch out for yourself and see what you think. Your family and friends will happily be your taste testers as well when they hear what’s on the menu. You’ll find that after just one batch, you staring finding reasons to make another…and another…and another.

In a large mixing bowl, cream butter and sugar together about 3-4 minutes.

In a separate mixing bowl, combine all of the dry ingredients for the cupcakes.

Fill the cupcake tin about halfway.
Bake 15-17 minutes.
Let the cupcakes cool in the pan for 5 minutes and finish cooling on a cooling rack.

FOR THE FILLING:

Put the egg yolks in a medium-sized bowl and gently beat them together.
Set aside. In a large saucepan mix together the sugar, cornstarch, and milk until smooth.
Heat over medium-high, stirring continuously until it starts to thicken. Allow to cook and simmer 2 additional minutes and remove from heat.

Heat the mixture over medium heat, bring to a simmer and allow to cook 2 additional minutes.

Allow to sit for 5 minutes, then whisk until completely smooth.

TO ASSEMBLE:

Cut the tops of the cupcakes off, and scoop out a good bit of the center.
Transfer the filling to a piping bag and fill the center of each cupcake (or you could use a spoon, it would just be a little messier), and return the tops of the cupcakes.
Dip the tops of the cupcakes in the chocolate ganache.
Refrigerate cupcakes until ready to serve.
