Ingredients

Scale

Brownie Base

¾ cup semisweet chocolate, coarsely chopped
¾ cup unsalted butter
¾ cup white sugar
¾ cup packed brown sugar (light or dark)
3 eggs (at room temperature)
2 teaspoons vanilla extract
Few drops almond extract (optional but recommended)
1 ½ tablespoons unsweetened cocoa powder
1 cup all-purpose flour

Peanut Butter Swirl

⅔ cup creamy peanut butter
5 tablespoons powdered sugar
½ teaspoon vanilla extract (optional)
2 tablespoons heavy cream (double cream also works)

Instructions

Prepare the Pan: Preheat your oven to 350ºF (180ºC). Grease or spray an 8-inch square metal baking pan, then line the bottom and two sides with parchment paper, leaving the other two sides unlined.
Melt Chocolate and Butter: In a large glass bowl, melt ¾ cup chopped semisweet chocolate and ¾ cup unsalted butter together. You can do this in the microwave, stirring every 10 seconds until smooth, or using a double boiler, stirring constantly.
Add Sugars: Stir in ¾ cup white sugar and ¾ cup packed brown sugar into the melted chocolate mixture until fully incorporated. This lets the mixture cool slightly before adding eggs.
Combine Wet Ingredients: Add 3 room temperature eggs, 2 teaspoons vanilla extract, a few drops of almond extract (if using), and 1 ½ tablespoons unsweetened cocoa powder to the chocolate mixture. Mix until smooth and well combined.
Add Flour: Gradually add 1 cup all-purpose flour in two portions, folding gently until just combined. Avoid overmixing to maintain brownie tenderness.
Transfer Batter: Spread the brownie batter evenly into the prepared baking pan.
Make Peanut Butter Swirl: In a medium bowl, blend ⅔ cup creamy peanut butter, 5 tablespoons powdered sugar, ½ teaspoon vanilla extract (if using), and 2 tablespoons heavy cream until smooth with no lumps.
Apply Swirl: Drop spoonfuls of the peanut butter mixture over the brownie batter in the pan. Using a knife, swirl lightly to create marbled patterns but leave some peanut butter chunks intact for texture.
Bake: Bake in the preheated oven for 25-30 minutes. The brownies are done when a toothpick inserted in the center comes out with fudgy crumbs and the surface looks dry, while the center still jiggles slightly. Avoid overbaking for the best fudgy texture.
Cool: Remove from oven and cool completely on a wire rack before slicing.
Store and Serve: For best flavor and texture, let the brownies rest overnight wrapped in plastic wrap. They can be frozen well-wrapped for up to one month.

Notes

Use a metal pan rather than glass for even baking and better crust formation.
Room temperature eggs help to blend the batter evenly.
Do not overmix the batter to keep brownies tender and fudgy.
The almond extract is optional but highly recommended for enhancing flavor.
Baking times may vary depending on your oven and pan thickness; check closely starting at 25 minutes.
Peanut butter swirl is key for texture contrast – swirl gently to retain chunks.
Brownies taste better the next day after resting.
Store wrapped at room temperature or refrigerate for longer freshness.
Freeze well-wrapped for up to one month and thaw before serving.
