In a large bowl, whisk together the flour, sea salt, baking powder, baking soda, and cinnamon.
3 cup flour, 1 tsp fine sea salt, ½ tsp baking powder, ½ tsp baking soda, ½ tsp cinnamon
In a separate mixing bowl cream together the softened butter, light brown sugar, and granulated sugar. Mix in the eggs and vanilla extract.
1 cup butter, ½ cup light brown sugar, ½ cup sugar, 2 large egg, 2 tsp vanilla extract
Add the wet mixture to the flour mixture and mix just until combined. Fold in the milk chocolate M&M candies and peanut butter M&M candies.
½ cup M&M candies, ¾ cup peanut butter M&M candies
Place scoops of cookie dough onto the prepared sheets leaving about 1 inch in between each cookie. Use the palm of your hand or the bottom of a glass to flatten the cookies into circles.
Bake for 8-10 minutes or until just beginning to brown. Allow to cool on the baking sheet for 10 minutes before removing to cool completely.
