Fudgy Peanut Butter Brownies You’ll Dream About

Hey friends!
Today, I’m excited to share a baking recipe that’s pure comfort in every bite—rich, fudgy Peanut Butter Brownies that melt in your mouth and satisfy every craving for chocolate, peanut butter, and that chewy brownie bliss.

Picture this: a deep, chocolatey base with crackly tops, swirling ribbons of creamy peanut butter throughout, and just the right amount of chew. These brownies strike the perfect balance between decadence and nostalgia, like a warm hug in dessert form.

Growing up, peanut butter was a pantry staple and brownies were a birthday staple. One day, I swirled in a spoonful of peanut butter “just to see” and never looked back. Chocolate and peanut butter were meant to be, and this recipe proves it in every gooey square.

And yes—this is a baked recipe, because the heat brings out the deep cocoa flavor and gives us that irresistible texture. Think soft centers, chewy edges, and those peanut butter ribbons that toast up golden and fragrant.

Let’s dive in and make magic in your kitchen!

Ingredients

Brownie Batter

Ingredient	Substitutions/Notes
1/2 cup (1 stick) unsalted butter	Can use salted; just reduce added salt by half
1 cup granulated sugar	Swap 1/4 cup with brown sugar for a moister crumb
2 large eggs	Room temp = better texture
1 tsp vanilla extract	Optional but recommended
1/3 cup unsweetened cocoa powder	Dutch-processed gives a richer color, but natural cocoa works
1/2 cup all-purpose flour	Don’t overpack—spoon and level!
1/4 tsp salt	Enhances chocolate flavor

Peanut Butter Swirl

Ingredient	Substitutions/Notes
1/3 cup creamy peanut butter	Natural PB works, but stir well and avoid runny kinds
1 tbsp powdered sugar	Helps firm the swirl slightly; skip if you like it softer

Step-by-Step Instructions

Step 1: Preheat & Prepare the Pan

• Preheat oven to 350°F (175°C).
• Line your pan with parchment or lightly grease it. Parchment makes cleanup (and lifting) easier.

Step 2: Melt Butter & Mix Base

• In a medium bowl, melt the butter (microwave 30–45 seconds).
• Whisk in sugar until glossy and smooth.
• Add eggs and vanilla. Whisk until pale and slightly thickened—this gives that shiny top.

Pro Tip: Whipping the eggs into the sugar helps create that iconic brownie crust!

Step 3: Stir in Dry Ingredients

• Sift in cocoa powder, flour, and salt.
• Gently fold with a spatula just until combined. Don’t overmix! Batter should be thick and glossy.

Step 4: Swirl in the Peanut Butter

• In a small bowl, stir together peanut butter and powdered sugar.
• Pour brownie batter into the pan and smooth the top.
• Drop spoonfuls of peanut butter over the batter. Use a knife or toothpick to gently swirl—don’t overdo it or you’ll lose the beautiful marbled look.

Step 5: Bake to Perfection

• Bake for 30–35 minutes, until a toothpick comes out with a few moist crumbs.
• Let cool in the pan for 20 minutes before slicing.

Checkpoints:

• Edges should look set and slightly pulled from the pan.
• Center should still be a little soft when pressed, but not jiggly.

Troubleshooting & FAQ

Problem	Solution
