Step-by-Step Cooking Instructions
Pre-Cooking Prep
In a large bowl, whisk together the melted butter and sugar until smooth and glossy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet ingredients just until combined. Do not overmix.
Cooking Method (Times & Temps)
Pour the brownie batter into the prepared pan and spread evenly.
Sprinkle M&M’s evenly over the top, gently pressing them into the batter so they stick.
Bake at 350°F for 30–35 minutes, or until the edges are set and a toothpick inserted near the center comes out with moist crumbs.
Doneness or Texture Check
The brownies should be:
-
Set around the edges
-
Slightly soft in the center
-
Glossy on top with light cracking
Avoid baking until completely firm, which can dry them out.
Resting or Final Touches
Let the brownies cool completely in the pan. Lift out using parchment paper and slice into squares once fully cooled for clean edges.
