Preheat the oven to 350º F.
In a small bowl, add the wet ingredients and whisk to blend.
In a larger bowl, add the dry ingredients and whisk to blend.
Pour the wet ingredients into the dry ingredients and mix. You want the batter to be smooth, but not too runny.
Add parchment paper cupcake/muffin liners to a muffin tin. Fill each ¾ with the cupcake batter.
Bake the cupcakes for 20-22 minutes until done.
Remove the cupcakes from the oven and put each cupcake onto a cooling rack to cool for 30 minutes.
Take the middle scooper if you want to fill your cupcakes and remove the middle of each cupcake.
Fill each cupcake with your preferred topping. (There is a list in the post, but ideas include jam, Nutella, M&Ms, etc).
In a mixer, add frosting ingredients and whip until thick and creamy.
Put the filling into a frosting pastry bag. Make sure to put the frosting tip in! Add frosting, including over the hole with the stuffing.
Serve and enjoy!
