If you make these without using a muffin top pan, line your baking sheet with parchment paper or a Silpat. Space the cookies out 2" apart and drop by rounded tablespoons onto baking sheet. Bake 8-9 minutes until edges are golden.
Prepare your muffin pan by first spraying with cooking spray, next lining each tin with a parchment round. (Cut the parchment to fit in the bottom of the pan) and then spraying the parchment again lightly. Set aside
Cream butter and sugars together in mixer. Turn speed to low and add eggs and vanilla. Turn up to medium for approximately 20 seconds until batter in combined.
Turn mixer to low and add in flour, baking soda and sea salt. When just mixed together fold in your chopped Milky Way.
Press 1/4 cup batter into each muffin top and bake for 13-15 minutes until the edges are golden and the center is JUST set.
Remove from oven and let cool in pan for 5 minutes. Loosen edges with a knife and flip the cookies onto a wire cooling rack.
