There’s something universally comforting about the swirl of peanut butter and chocolate.

I remember my grandmother pulling out her worn, cocoa-stained recipe card, the one she had scribbled on years ago in her elegant cursive. As she stirred, the scent of melted chocolate would fill the air, signaling that something delicious was on the way.
These brownies aren’t just dessert—they’re a ritual. Whether you’re baking them for a celebration, a cozy fall afternoon, or a quiet evening with tea, they represent the simple joys in life.

These brownies aren’t just dessert—they’re a ritual. Whether you’re baking them for a celebration, a cozy fall afternoon, or a quiet evening with tea, they represent the simple joys in life. Chocolate and peanut butter, two pantry staples, come together in perfect harmony to make something that feels indulgent but requires minimal effort.

Ingredients
1 cup (227 g) unsalted butter
1¼ cups (175 g) semisweet chocolate chips
1¼ cups (150 g) all-purpose flour
½ cup (50 g) unsweetened cocoa powder
1 tsp salt
1 cup (200 g) granulated sugar
1 cup (220 g) packed light brown sugar
3 large eggs
1 Tbsp vanilla extract
½ cup creamy peanut butter
Instructions
1. Melt the base:
In a saucepan over low heat, melt the butter and ¾ cup of the chocolate chips, stirring until glossy. Let cool for 5 minutes before proceeding.
2. Sift dry ingredients:
In a medium bowl, sift the flour, cocoa powder, and salt. This prevents clumps and ensures even texture.
3. Whisk wet ingredients:
In a large bowl, whisk the slightly cooled chocolate mixture with granulated sugar and brown sugar until thick and creamy. Add eggs one at a time, mixing well after each. Stir in the vanilla.
4. Combine wet and dry:
Gradually stir the dry ingredients into the wet mix until just combined. Fold in the remaining chocolate chips.
5. Swirl with peanut butter:
Pour the batter into a parchment-lined 8×8-inch pan. Drop spoonfuls of peanut butter across the top and use a knife or toothpick to create elegant swirls—don’t overdo it or you’ll lose the marble effect.
6. Bake:
Bake at 350°F for 40–45 minutes or until a toothpick inserted comes out with moist crumbs. For gooier brownies, pull them out at around 35 minutes.
7. Cool completely:
Let the brownies cool in the pan. This step helps them set properly for clean slicing.
Notes
You can double the recipe for a 9×13-inch pan—adjust baking time to 45–50 minutes. For a deeper chocolate flavor, use dark chocolate chips.

HELPFUL TIPS:
- Peanut Butter Swirls: If your peanut butter is too stiff, microwave it for 10–15 seconds to make swirling easier.
- Cooling Time Matters: Don’t rush the cooling process—it ensures perfect fudgy texture.
- Mix Smart: Use a wooden spoon or silicone spatula instead of a hand mixer to avoid overmixing.
- Grease the Pan Well: Even with parchment, a little butter under the paper makes removal easier.

FREQUENTLY ASKED QUESTIONS:
Can I use natural peanut butter?
Yes, but be sure it’s well-stirred. Natural peanut butter tends to be runnier and may change the swirl consistency.
What’s the best way to store peanut butter brownies?
Store in an airtight container at room temperature for up to 4 days. For longer storage, freeze them individually and thaw before serving.
How do I know when they’re done baking?
The edges will look set, but the center may jiggle slightly. Insert a toothpick—it should come out with moist crumbs, not raw batter.
Can I make these gluten-free?
Yes, substitute all-purpose flour with a gluten-free 1:1 baking blend.
STORAGE INSTRUCTIONS:
Keep the brownies at room temperature for short-term snacking. Wrap tightly in plastic or foil to preserve moisture. To freeze, wrap each piece individually in parchment and place in a zip-top bag—perfect for portioning out later.
