Let’s Make it Together

Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan with non-stick spray or line it with parchment paper for easy removal later.

Create Your Base Batter: In a large mixing bowl, melt the unsalted butter in the microwave or over low heat on the stove until just melted. Stir in granulated sugar and brown sugar until combined and smooth—this step is crucial for that crusty exterior!

Add Eggs and Vanilla: Incorporate the eggs one at a time into your buttery mixture, mixing well after each addition. Add vanilla extract next—your kitchen will smell heavenly!

Sift Dry Ingredients: In another bowl, whisk together cocoa powder, flour, baking powder, and a pinch of salt. Gradually fold this dry mix into your wet ingredients until just combined—don’t overmix or you’ll lose that lovely fudginess.

Toss in Oats and Chocolate Chips: Gently fold rolled oats along with chocolate chips (and optional M&Ms or nuts) into the brownie batter. The mixture should be thick but manageable—the kind that makes you want to dive right in!

Bake to Perfection: Pour your batter into the prepared baking pan, spreading evenly. Bake for 25-30 minutes until edges look firm but center is slightly soft—this ensures those fudgy vibes! Allow cooling before cutting into squares.
