Chocolate Guinness Cupcakes with Creamy Bailey's Frosting

Make the Cupcakes
1 Preheat oven to 375°F. Line a cupcake tin with liners, and set aside.
2 Combine the flour, cocoa powder, baking soda, baking powder and salt in a large bowl. Whisk together until incorporated.
3 In another mixing bowl, cream together the eggs, mascarpone, and sugar using a hand mixer or a stand mixer.
4 Pour the Guinness into the wet ingredients, and stir until combined.
5 Pour the wet ingredients into the dry ingredients and whisk until just combined. You don't want to overmix this and don't need to worry about lumps!
6 Pour the batter into cupcake liners using a cookie scoop or a measuring cup.
7 Bake for 15-20 minutes or until a toothpick comes out clean.
8 When the cupcakes are baked through, remove from the oven, and let them cool completely.
Make the Irish Cream Frosting
10 Combine the mascarpone, Irish cream and powdered sugar in a large bowl.
11 Beat the ingredients with a hand mixer until smooth.
12 Once the cupcakes have cooled completely, dollop the frosting on top of them. (You can also use a pastry bag and swirl the frosting onto the cupcakes.)
13 Decorate the cupcakes with sprinkles or any other type of edible decoration before enjoying.
