Introduction

These Chocolate Butter Brownies combine rich, fudgy chocolate with creamy peanut butter swirls for a decadent treat. Easy to make and perfect for peanut butter lovers, they offer the perfect balance of sweet and nutty flavors.

The image shows a stack of three thick brownies with visible layers of dark chocolate and creamy peanut butter swirled together. Each brownie has a rich, glossy dark brown chocolate layer mixed unevenly with a smooth, light golden peanut butter layer, creating a marbled effect. The brownies look moist and dense with a slightly crumbly texture on the edges. The stack is placed on a white marbled surface with a few scattered dark chocolate chips nearby. The background is softly blurred white, keeping the focus on the brownies. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 ½ cups creamy all natural peanut butter
⅔ cup powdered sugar
½ cup melted butter
1 ¼ cup chocolate chips
1 cup granulated sugar
2 eggs
3 tbsp cocoa powder
1 tsp vanilla extract
¼ cup flour (all purpose or gluten free flour)
⅓ cup creamy all natural peanut butter (to swirl)

Instructions

Step 1: Preheat the oven to 350 degrees Fahrenheit. Line an 8 inch by 8 inch square pan with parchment paper.
Step 2: Make the peanut butter filling by combining 1 ½ cups creamy peanut butter and powdered sugar in a bowl. Stir until thick and well combined, then set aside.
Step 3: In another bowl, mix melted butter and chocolate chips. Stir until the chocolate is fully melted and creamy. Use a quick microwave burst if needed to melt completely.
Step 4: In a clean mixing bowl, whisk granulated sugar and eggs vigorously for 2 minutes until smooth and slightly fluffy.
Step 5: Pour the melted chocolate mixture into the sugar and egg mixture. Stir to combine evenly.
Step 6: Add cocoa powder, vanilla extract, and flour. Stir gently until all ingredients are incorporated and the batter is smooth.
Step 7: Pour half of the brownie batter into the prepared pan and spread evenly.
Step 8: Drop dollops of the peanut butter filling over the brownie batter. Use your hands to spread and flatten the peanut butter layer; it doesn’t need to be perfect.
Step 9: Pour the remaining brownie batter on top, covering the peanut butter layer.
Step 10: Drizzle ⅓ cup creamy peanut butter over the top of the batter. Use a knife or toothpick to swirl it through.
Step 11: Bake for 28 to 30 minutes until the middle is set and the brownies no longer jiggle when you gently shake the pan.
Step 12: Remove from oven and allow the brownies to cool completely before slicing and serving.

Tips & Variations

Use natural peanut butter with no added sugar for a less sweet filling and more pronounced peanut flavor.
For extra texture, sprinkle chopped peanuts or walnuts on top before swirling the peanut butter.
If you prefer a gluten-free option, substitute the all-purpose flour with an equal amount of gluten-free flour blend.
To intensify the chocolate flavor, add a pinch of espresso powder to the batter.

Storage

Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week or freeze for up to 2 months. To reheat, warm individual pieces in the microwave for 10-15 seconds for a soft, gooey texture.

How to Serve

A tall stack of three thick brownies shows clear layers of dark chocolate and creamy peanut butter swirled together. Each layer is uneven, with rough edges and a glossy, slightly melted texture that looks soft and gooey. The top of the stack has a marbled pattern where the dark chocolate meets the light peanut butter, adding a rich contrast. The brownies sit on a white marbled surface with a few chocolate chips scattered in front, giving a sense of the ingredients used. The background is softly blurred in white, making the dessert the main focus. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use crunchy peanut butter instead of creamy?

Yes, crunchy peanut butter can be used but it will change the texture of the filling with added crunch. It’s a delicious variation if you enjoy a bit of extra texture.

How do I know when the brownies are done baking?

The brownies are ready when the middle looks set and doesn’t jiggle when you shake the pan gently. Insert a toothpick near the center; it should come out with just a few moist crumbs but no wet batter.
