Decadent Raspberry Swirl Brownies Recipe
Introduction
These Decadent Raspberry Swirl Brownies combine rich chocolate with a tangy raspberry twist, creating a perfect balance of flavors. They’re fudgy, fruity, and make an impressive treat for any occasion.

Ingredients
- 1/2 cup butter
- 1 1/2 cups semi-sweet chocolate chips (225 grams)
- 3 eggs
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/2 teaspoon salt
- 1/8 teaspoon baking soda
- 1/8 teaspoon baking powder
- 1/2 cup raspberries, fresh or frozen
- 1/2 cup sugar
- A small amount of water
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease or line an 8×8 inch baking pan with parchment paper.
- Step 2: Melt the butter and chocolate chips together in a heatproof bowl over simmering water or in short bursts in the microwave, stirring until smooth.
- Step 3: In a separate bowl, whisk the eggs, 1 cup sugar, and vanilla extract until well combined and slightly thickened.
- Step 4: Slowly pour the melted chocolate mixture into the egg mixture, stirring gently to combine.
- Step 5: Sift together the flour, salt, baking soda, and baking powder, then fold into the chocolate batter carefully without overmixing.
- Step 6: Transfer the batter into the prepared pan and spread evenly.
- Step 7: In a small saucepan, combine raspberries, 1/2 cup sugar, and a splash of water. Cook over medium heat until berries release juice and sugar dissolves, forming a syrup (about 5 minutes). Let it cool slightly.
- Step 8: Drop spoonfuls of the raspberry syrup over the brownie batter and use a skewer or knife to gently swirl the raspberry through the batter, creating a marbled effect.
- Step 9: Bake for 25–30 minutes, or until a toothpick inserted near the center comes out with moist crumbs but not wet batter.
- Step 10: Allow brownies to cool completely in the pan before slicing and serving.
Tips & Variations
- Use fresh raspberries for a brighter flavor or frozen raspberries if fresh aren’t available; just thaw and drain excess liquid before cooking.
- For a richer taste, add a tablespoon of espresso powder to the chocolate mixture.
- Try swirling in other fruit compotes like blackberry or cherry for a different fruity twist.
- If you prefer less sweetness, reduce the sugar in the raspberry syrup by a quarter cup.
Storage
Store brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. Warm briefly in the microwave before serving to restore softness.

FAQs
Can I use freeze-dried raspberries instead of fresh or frozen?
Freeze-dried raspberries won’t provide the same juicy syrup texture but can be sprinkled on top after baking for a concentrated raspberry flavor and crunch.
How do I know when the brownies are perfectly baked?
Check by inserting a toothpick near the center; it should come out with moist crumbs but no wet batter. Overbaking can dry them out, so start checking around 25 minutes.

Ingredients
Brownie Batter
- 1/2 cup butter
- 1 1/2 cups semi-sweet chocolate chips (225 grams)
- 3 eggs
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/2 teaspoon salt
- 1/8 teaspoon baking soda
- 1/8 teaspoon baking powder
Raspberry Swirl
- 1/2 cup raspberries, fresh or frozen
- 1/2 cup sugar
- A small amount of water
Instructions
- Prepare Raspberry Sauce: In a small saucepan, combine the raspberries, 1/2 cup sugar, and a small amount of water over medium heat. Cook while stirring occasionally until the raspberries break down and the mixture thickens slightly, about 5-7 minutes. Remove from heat and strain through a fine sieve to remove seeds. Set aside to cool.
- Melt Butter and Chocolate: In a heatproof bowl, melt the butter and semi-sweet chocolate chips together over a double boiler or in short bursts in the microwave, stirring frequently until smooth. Allow the mixture to cool slightly.
- Mix Wet Ingredients: In a large bowl, whisk together the eggs, granulated sugar, and vanilla extract until the mixture is light and fluffy.
- Combine Chocolate Mixture and Eggs: Slowly add the melted butter and chocolate mixture to the egg mixture, stirring constantly to combine thoroughly.
- Add Dry Ingredients: Sift together the flour, salt, baking soda, and baking powder. Gradually fold these dry ingredients into the wet mixture until just combined, ensuring not to overmix.
- Assemble Brownies: Pour half of the brownie batter into a greased or parchment-lined baking pan. Drizzle half of the raspberry sauce over the batter. Pour the remaining brownie batter on top, then swirl the remaining raspberry sauce over the top using a knife or skewer to create a marbled effect.
- Bake: Preheat the oven to 350°F (175°C). Bake the brownies for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Cool and Serve: Remove the brownies from the oven and let them cool completely in the pan on a wire rack before cutting into squares. This allows the raspberry swirl to set and makes cutting easier.
Notes
- You can use fresh or frozen raspberries interchangeably for the swirl.
- Allow the raspberry sauce to cool before swirling to prevent it from blending too much with the batter.
- For a more intense chocolate flavor, use dark chocolate chips instead of semi-sweet.
- Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- These brownies can be frozen for up to 2 months; thaw completely before serving.
