Rich Reeses Pieces Peanut Butter Brownies

It was one of those quiet Austin afternoons when the rain tapped softly against the window, and the whole world seemed to move slower. The air smelled faintly of coffee from the café downstairs, and I found myself restless, looking for something to bake.

Reaching into the cupboard, a bag of Reese’s Pieces slipped from the shelf and scattered across the counter, bright and playful against the dim kitchen light. That little burst of color sparked a thought, if peanut butter brownies were comfort, maybe this version could be pure joy.

I’ve baked plenty of brownies before, but peanut butter ones always have a way of feeling like home. They blend the richness of chocolate with that familiar, nutty warmth that pulls you back to childhood. As the butter melted and mixed with sugar, the kitchen filled with that sweet, roasted scent of peanut butter. No fancy layers, no frosting, just a simple batter swirled with peanut butter and dotted with colorful Reese’s crunch.

By the time they baked to a golden crust, the apartment had transformed. The windows steamed gently, the playlist hummed low, and the cat had claimed a front-row seat to watch the oven. When I finally pulled the pan out, the brownies gleamed, soft centers, crisp edges, and flecks of color shining through. It wasn’t a grand dessert, but it carried the warmth of an afternoon well spent, the kind that turns an ordinary day into something quietly special.

Short Description

Rich Reeses Pieces Peanut Butter Brownies are soft, dense, and irresistibly nutty, filled with rich peanut butter flavor and dotted with colorful candy crunch, perfect for bake sales, family desserts, or indulgent weekend baking.

Key Ingredients

• ⅔ cup butter, melted
• 1⅓ cups granulated sugar
• 1 cup light brown sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1 cup creamy or chunky peanut butter
• 2 cups all-purpose flour
• 2 teaspoons baking powder
• ¼ teaspoon salt
• ½ cup Reese’s Pieces (plus extra for topping, optional)

Tools Needed

• 11 x 13-inch baking pan
• Parchment paper
• Mixing bowls (large and medium)
• Whisk and rubber spatula
• Measuring cups and spoons

Cooking Instructions

Step 1: Preheat and Prepare
Preheat oven to 350°F (175°C). Line an 11 x 13-inch pan with parchment, leaving overhang for easy lifting.

Step 2: Mix Wet Ingredients
In a large bowl, combine melted butter, granulated sugar, brown sugar, and peanut butter. Whisk until smooth. Add eggs one at a time, followed by vanilla and salt. Mix gently until fully combined.

Step 3: Combine Dry Ingredients
In a separate bowl, whisk flour and baking powder. Slowly add to the wet mixture, folding until just incorporated. Avoid overmixing to maintain a dense, fudgy texture.

Step 4: Add Candy and Bake
Pour batter into the pan, smoothing evenly. Sprinkle Reese’s Pieces over the top. Bake 30–35 minutes, until the surface is set and a toothpick comes out with moist crumbs.

Step 5: Cool and Slice
Let cool in the pan for at least 30 minutes. Lift using parchment and slice into squares.
