Preheat your oven to 350 degrees and line your cupcake pan with liners and set aside.
In a small bowl mix together the flour, baking powder, baking soda and salt - set aside.
In the medium bowl mix the melted butter and sugar together, the mixture will be gritty.
Add the egg whites, greek yogurt, milk and vanilla bean extract and mix until well combined.
Slowly fold in the dry ingredients to the wet ingredients and mix until no lumps remain - the batter will be thick.
Fill all 12 cupcake liners evenly and bake for 18-19 minutes - do not bake longer than 20 minutes - mine were ready right at 18 minutes.
Allow to cool on a wire rack before frosting
Cookie Dough Frosting
Beat your butter and sugar together until well combined.
Mix in the vanilla and flour and mix until everything is well combined,
Beat in milk until you've reached your desired consistency.
Fold in the chocolate chips.
This frosting is a bit thick, I scooped mine on with a cookie scoop. You can frost with a knife, I wouldn't suggest piping this frosting as its very thick.
