Cooking Instructions

Follow these simple steps to prepare this delicious Reese’s Peanut Butter Cup Brownies:

Step 1: Preheat Your Oven

Begin by preheating your oven to 350°F (175°C). Grease a baking pan (9×13 inches works great) with non-stick cooking spray or line it with parchment paper for easy removal later.

Step 2: Melt the Butter

In a medium saucepan over low heat, melt the unsalted butter gently—stir continuously so it doesn’t burn. Once melted, remove from heat and let cool slightly while you prepare other ingredients.

Step 3: Mix Sugars

Add granulated sugar and brown sugar to the melted butter. Stir until combined well; this helps dissolve the sugars before adding eggs.

Step 4: Add Eggs

Mix in two large eggs one at a time until fully incorporated. The mixture should look glossy and smooth—it’s starting to come together beautifully!

Step 5: Incorporate Dry Ingredients

In another bowl, whisk together flour and cocoa powder until combined. Gradually add this dry mixture into the wet ingredients while stirring gently until just combined. Avoid overmixing; we want tender brownies here!

Step 6: Add Peanut Butter Cups

Fold in those chopped Reese’s Peanut Butter Cups! You’re creating little pockets of heaven within each bite—yum!

Transfer your brownie batter into the prepared pan evenly and bake for about 25–30 minutes or until a toothpick inserted comes out clean or with just a few moist crumbs clinging.

End with a serving suggestion: Once cooled slightly, cut into squares and serve warm topped with more chopped Reese’s if you’re feeling extra indulgent! Enjoy every gooey bite of these delightful brownies!
