Strawberry Brownies Fudgy Chocolate Swirl (Printable)

Rich fudgy chocolate meets sweet strawberry swirls in these indulgent marbled squares

# What You Need:

→ Strawberry Swirl

01 - 1 cup fresh strawberries, hulled and halved
02 - 2 tablespoons granulated sugar
03 - 1 teaspoon lemon juice

→ Brownie Batter

04 - 1/2 cup unsalted butter
05 - 4 ounces bittersweet chocolate, chopped
06 - 3/4 cup granulated sugar
07 - 2 large eggs
08 - 1 teaspoon vanilla extract
09 - 1/4 teaspoon salt
10 - 2/3 cup all-purpose flour
11 - 1/4 cup unsweetened cocoa powder

# Steps:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, allowing overhang for easy removal.
02 - Combine strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat for 5–7 minutes, stirring occasionally, until strawberries break down and mixture thickens. Mash or blend until smooth, then set aside to cool.
03 - Place butter and chocolate in a microwave-safe bowl. Microwave in 30-second intervals, stirring until smooth. Let cool slightly.
04 - Whisk sugar, eggs, vanilla, and salt into the melted chocolate mixture until glossy and well combined.
05 - Sift flour and cocoa powder over the batter. Fold gently until just incorporated, being careful not to overmix.
06 - Spread batter evenly in prepared pan. Drop spoonfuls of cooled strawberry puree over surface. Use a skewer or knife to gently swirl puree into batter, creating a marbled pattern.
07 - Bake for 28–32 minutes, or until a toothpick inserted in center comes out with a few moist crumbs. Avoid overbaking for fudgy texture.
08 - Cool completely in pan before lifting out using parchment overhang. Cut into squares for serving.

# Expert Hints:

01 -
  • The marbled pattern makes these look like they came from a bakery window
  • Fudgy chocolate meets bright strawberry in every single bite
  • Ready in under an hour but impressive enough for special occasions
02 -
  • Room temperature ingredients prevent the chocolate from seizing when you mix everything together
  • Overbaking makes them dry, so pull them out when they still have a slight wobble in the center
  • Cold strawberry puree keeps the swirl distinct instead of blending completely into the batter
03 -
  • Gently run your knife through the batter in one continuous motion for the cleanest marble pattern
  • If your strawberries aren't very sweet, add an extra teaspoon of sugar to the puree before cooking
