Fudgy chocolate brownies marbled with homemade strawberry swirl for a delightful fruity twist on a classic favorite.

# 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 oz 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

# How To Make It:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an 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 with fork or blend until smooth. Set aside to cool.
03 - In microwave-safe bowl, melt butter and chocolate in 30-second intervals, stirring until smooth. Let cool slightly.
04 - Whisk sugar, eggs, vanilla, and salt into chocolate mixture until glossy and well combined.
05 - Sift flour and cocoa powder into batter. Fold gently until just incorporated.
06 - Spread brownie batter evenly in prepared pan.
07 - Drop spoonfuls of strawberry puree over batter. Use skewer or knife to gently swirl puree into brownie mixture for marbled effect.
08 - Bake for 28-32 minutes until toothpick inserted in center comes out with a few moist crumbs.
09 - Cool completely in pan, then lift out and cut into squares.

# Expert Suggestions:

01 -
  • The strawberry swirl keeps these brownies incredibly moist without making them soggy
  • They look stunning with that marble pattern but require almost zero decorating skills
02 -
  • The strawberry puree must cool completely before swirling or it will sink to the bottom during baking
  • Underbaking slightly is better than overbaking, as these continue to firm up while cooling
03 -
  • If the strawberry mixture seems too thick, add a teaspoon of water to help it swirl more easily
  • For extra chocolate chunks, fold in a half cup of chocolate chips before adding the strawberry swirl
