These fudgy m&m brownies are perfect for M&M candy lovers! You only need simple ingredients and one bowl to make them. They have perfect crinkle tops and delicious chocolate flavor in every single bite!
Line a square metal 8x8 baking pan (see notes below) with parchment paper to cover all four sides. Then preheat the oven to 350 F/180 C.
Melt the butter and chocolate chips together until smooth. Then whisk in the cocoa powder. Set aside.
Whisk the sugars, eggs, egg yolk, and vanilla extract. Then whisk in the melted butter and chocolate mixture until just combined.
Fold in the flour, espresso powder, and salt until almost combined. Then fold in the M&M's and chocolate until just combined.
Pour the brownie batter into the prepared pan and top with more M&M's. Bake for 33-40 minutes, or until a toothpick inserted into the center comes out covered in a few moist crumbs.
Let the pan cool completely on a wire rack before removing, then cut into 16 brownies and enjoy!
Store leftover M&M brownies in an airtight container at room temperature for 2-3 days.

Notes
*Measure your flour properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*** Use a square pan. You must use a square metal 8x8 baking pan with square edges as shown. Glass or ceramic pans retain heat differently. A pan with rounded edges will need to bake longer than the bake time!M&M candies: Regular milk chocolate M&M's are used in this recipe. You can also add mini M&M's or different m&m flavors.
