Preheat oven to 350 F and prepare a muffin tin with 6 liners.
In a large bowl, stir together all the dry ingredients. Add in the wet ingredients and stir until a batter forms.
Divide the batter among the cupcake liners and bake for 18-22 minutes. Once cooled, place all frosting ingredients into a bowl and beat using a handheld mixer until light and fluffy.
