Preheat oven to 350 degrees. Line a 9×13 pan with tin foil; coat lightly with cooking spray. In a large bowl, whisk melted butter and brown sugar. Stir in peanut butter until smooth.
In a separate bowl, combine flour, baking powder, baking soda, and salt.
Add the vanilla; stir until combined. Add the eggs one at a time, stirring until fully incorporated. Gently add the flour mixture; use a rubber spatula to fold in. Fold in 1 cup M&Ms.
Spread batter into prepared pan; smooth it out with a spatula (or your hands) until evenly distributed. Top with remaining 1/2 cup of M&Ms and lightly press them into the batter. Bake for 25 minutes or until edges are just golden brown.
Allow blondies to cool for at least 45 minutes. Melt semisweet chocolate chips and shortening in a small bowl in the microwave. Stir until completely smooth. Drizzle over cooled blondies. Cut into squares and serve!
