Easy Boston Cream Pie Cupcakes

Boston cream pie cupcakes take everything you love about the classic dessert and turn it into a handheld treat. The cupcakes start with a cake mix to make them easy, but the homemade vanilla pudding filling and glossy chocolate ganache elevate them far beyond boxed cake territory.

Once the cupcakes are cooled, you’ll hollow out the centers, spoon in the pudding, and replace the cupcake piece “top” to keep the filling neatly tucked inside. A rich ganache gets spooned over each one and sets into a smooth, shiny layer that looks bakery-worthy.

They take a few extra steps to assemble, but each one is simple and worth it: the end result is impressive and delicious. They store in the fridge and stay moist because of the pudding so you’ll want to add these to your list of make ahead desserts for parties. They’ll stay fresh for several days (if they last that long!)
