Take classic tasty cookie and turn it into these Monster Cookie Cupcakes. Filled with peanut butter, oatmeal, chocolate chips and mini M&M's, you cannot go wrong!
Place the oats in a medium-sized heat-proof bowl. Pour the boiling water on top and let it sit until it cools to room temperature, about 90 minutes.
Preheat the oven to 350°F. Line a cupcake tin with liners, and set aside.
In a small bowl, whisk together the flour, baking soda, baking powder, and salt.
Add the chocolate chips to a small bowl. Add 1 tablespoon of the flour mixture and stir to combine so all of the chocolate chips are coated, set aside.
In a large bowl, cream together the brown sugar, butter, and peanut butter until smooth using an electric hand mixer.
Add the egg and vanilla, mix until smooth.
Add the cooled oatmeal and mix it in.
Then, add the flour mixture, and mix it in until there are no dry patches.
Add the chocolate chips and stir them in until just combined.
Divide the batter among the 12 cupcake liners in the tin, about 3 tablespoons each.
Bake for 14-17 minutes until a toothpick inserted into the center comes out clean. Let cool in the tin for 10 minutes, then take them out to cool completely on a wire rack.
Once the cupcakes are cool, make the frosting. Place the peanut butter and butter into the body of a stand mixer with the paddle attachment or into a large bowl with an electric hand mixer, and mix until smooth.
Add the powdered sugar a little at a time until mixed in. Scrape down the sides as needed.
Add the heavy cream and vanilla, and slowly stir it in. Once it is incorporated, turn up the speed to medium-high and whip for 3 minutes until light and fluffy.
Add the chocolate chips and M&M’s, I like to fold these in by hand until incorporated.
Top the cupcakes generously with the frosting. I like to use an ice cream scoop to do this. The chunks from the chocolate chips and M&M’s are too big to pipe the frosting. Serve immediately.
Notes
This recipe can be doubled if you'd like.
They can be frozen, see above on how to do that.
You can use less frosting if you'd like.
Add some mini M&M's or chopped peanuts to the batter for some more texture.
Do not skip soaking your oats, this is important to the texture of the cupcakes.
