Preheat oven to 350F. Prepare and 8×8-inch square pan with parchment paper and cooking spray. Set aside.

In a medium saucepan, let butter and chocolate over low heat. Remove the pan from the heat.

Stir in sugar, vanilla extract and eggs. Using a wooden spoon beat lightly until just combined.

Fold in the flour and the chocolate chips until just a few streaks of flour remain. Do not over-beat the batter.

Spread the brownie batter into the prepared baking pan then scatter the M&M candies over the top. Bake at 350 for 30 minutes. Do not over bake.

Remove the pan from the oven and let cool on wire rack. Cut and enjoy.
