Instructions

1. In a large bowl or the bowl of a stand mixer, cream together the butter and sugars until light and fluffy. Add the egg and vanilla then whisk again until incorported.
2. Switching to a wooden spoon or spatual, add flour, baking powder, baking soda and salt then mix until well combined.
3. Finally fold in the chocolate chips and the m&m's until they are well distributed throughout the cookie dough. Cover with cling and chill forat least 30 minutes.
4. When you are ready to bake, preheat oven to 350°F and line two baking sheets with parchment paper.
5. Using a small ice cream scoop or spoon, scoop the cookie dough into balls and lay them on the prepared baking sheet about 2 inches apart. We usually place 6 cookies per sheet. at this stage you can press some more M&M's and chocoalte chips onto the top of the cookies before baking so that they are visble after baking.
6. Bake cookies for 20 - 25 minutes tunring half way through, until the edges are slightly golden and the cookies are cooked. The bakign time will also depend on how big your cookies are.
7. Once the cookies are done, remove from oven, let cool slightly on baking tray before transfering to a cooling rack to cool completely.
