This decadent raspberry swirl brownies recipe brings a luscious twist to classic chocolate brownies. It’s perfect when you want something rich and fruity all at once, and surprisingly simple to whip up in your own kitchen.

This recipe became my go-to when I wanted a special dessert without fuss. The first time I made it, the swirl really wowed my friends and they kept asking for the recipe.

Gather Your Ingredients

  • Butter with a creamy texture: using unsalted gives you better control over saltiness
  • Semi-sweet chocolate chips: 225 grams creates a rich chocolate base, quality brands melt smoothly
  • Eggs: provide structure and moisture for fudgy brownies
  • Granulated sugar: balances bitterness from chocolate and adds sweetness
  • Vanilla extract: enhances the overall flavor depth
  • All-purpose flour: the foundation for structure; choose unbleached if possible
  • Salt: balances sweetness and intensifies chocolate
  • Baking soda and baking powder: light leavening agents to keep brownies slightly tender
  • Raspberries fresh or frozen: fresh are ideal but frozen work well if thawed gently
  • Sugar for raspberry sauce: sweetens and helps create a syrup with the berries
  • A small amount of water: to help the raspberry mix turn syrupy and swirl beautifully

How to Make It

Sauté the Chocolate Base:
Melt butter and semi-sweet chocolate chips together in a heatproof bowl over simmering water, stirring frequently until smooth. This creates a rich fudgy foundation for brownies.
Whisk Eggs and Sugar:
In a separate bowl, vigorously whisk eggs, granulated sugar, and vanilla extract until pale and slightly thickened. This aerates the mixture for a tender crumb.
Combine Dry Ingredients:
Sift together all-purpose flour, salt, baking soda, and baking powder to ensure even mixing and avoid clumps, then gradually fold into the egg mixture followed by the melted chocolate mixture.
Prepare Raspberry Swirl:
In a small saucepan, combine raspberries, sugar, and a splash of water over medium heat. Stir gently until the berries break down and the mixture becomes syrupy. Cool slightly.
Swirl and Bake:
Pour the brownie batter into a greased or parchment-lined baking dish. Dollop spoonfuls of the raspberry syrup across the top and use a knife or skewer to gently swirl the sauce into the batter, creating ribbons of raspberry.
Bake:
Bake at 350 degrees Fahrenheit for about 25 minutes or until a toothpick inserted near the center comes out with moist crumbs but no raw batter.
Cool and Serve:
Allow the brownies to cool completely before slicing. This helps the texture set perfectly and makes it easier to see the beautiful raspberry swirl in each piece.

The raspberry sauce is my favorite part, with its fresh tartness complementing the rich chocolate. I remember making these brownies for a friend’s birthday and watching her eyes light up when she saw the vibrant swirl on top.

Flavor Boosters

Store brownies in an airtight container at room temperature for up to three days to keep them moist and tender. For longer storage, wrap tightly and freeze for up to two months. Thaw overnight in the refrigerator before serving. Avoid refrigerating unless wrapped properly as cold temperatures can dry out the edges and dull flavors.

Serving Suggestions

Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent dessert experience. Pair with a cup of freshly brewed coffee or tea to balance the sweetness and highlight the raspberry notes. Cut into small squares for party platters or gift boxes.

Creative Twists

Use dairy-free butter and dairy-free chocolate chips for a vegan option. If you don’t have fresh raspberries, frozen berries work after thawing, or try swirl made with strawberry preserves for a similar effect. Brown sugar instead of granulated sugar yields a deeper caramel note but will alter texture slightly.

How to Make It

Step 01

Preheat oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, ensuring an overhang for easy removal.

Step 02

In a medium saucepan, melt butter and semi-sweet chocolate chips over low heat, stirring until smooth. Remove from heat and allow to cool slightly.

Slowly pour the cooled chocolate mixture into the egg mixture, whisking until fully incorporated.

Step 06

Gently fold the sifted dry ingredients into the chocolate mixture, mixing just until combined. Do not overmix.

Step 07

In a small saucepan over medium heat, combine raspberries, granulated sugar, and 2 teaspoons water. Stir and simmer for 5-7 minutes until berries have broken down and the mixture is syrupy. Remove from heat and strain to remove seeds, if desired.

Step 08

Pour brownie batter into prepared pan and spread evenly. Drop spoonfuls of raspberry sauce over the surface and use a knife or skewer to gently swirl the sauce through the batter.

Step 09

Bake in preheated oven for 25 minutes, or until the center is just set and a toothpick inserted comes out with a few moist crumbs.
