Decadent Raspberry Swirl Brownies Recipe
Introduction
These Decadent Raspberry Swirl Brownies combine rich, silky chocolate with a bright, fruity raspberry ribbon. The luscious swirl adds a refreshing twist to classic fudgy brownies, perfect for any chocolate lover looking for a special treat.

Ingredients
- 1 1/2 cups semi-sweet chocolate chips
- 1 tsp vanilla extract
- 1/2 cup unsalted butter
- 1/8 tsp baking soda
- 1/8 tsp baking powder
- 1/2 cup all-purpose flour
- 3 eggs (room temperature)
- 1/2 tsp salt
- 1 cup granulated sugar
- 1/2 cup granulated sugar (for raspberry swirl)
- A small amount of water (for raspberry swirl)
- 1/2 cup raspberries
Instructions
- Step 1: Line an 8-inch baking pan with parchment paper or foil, leaving some overhang for easy removal. Lightly coat the lining with cooking spray.
- Step 2: In a saucepan, combine raspberries, 1/2 cup sugar, and a small splash of water. Stir over medium heat until sugar dissolves and mixture turns saucy. Mash raspberries or blend for smoothness. Boil briefly, then remove from heat and strain to remove seeds. Set aside.
- Step 3: Preheat your oven to 350°F (175°C).
- Step 4: Melt butter and chocolate chips together over low heat until smooth. Remove from heat and let cool; refrigerate if needed to speed cooling.
- Step 5: In a separate bowl, whisk eggs with 1 cup sugar and vanilla extract until combined. Slowly add this mixture to the cooled chocolate blend, stirring constantly to prevent scrambling.
- Step 6: Add flour, salt, baking powder, and baking soda to the chocolate-egg mixture. Stir until smooth. Pour batter evenly into the prepared pan.
- Step 7: Spoon raspberry sauce in small dollops over the batter. Use a knife to gently swirl the sauce into the batter, creating a marbled effect.
- Step 8: Bake for 30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Cool completely in the pan before lifting out and slicing.
Tips & Variations
- Use fresh or frozen raspberries for the swirl; frozen can be thawed slightly before cooking.
- For extra fudginess, replace half the all-purpose flour with almond flour.
- Swirl in white chocolate or cream cheese along with raspberry sauce for added richness.
Storage
Store brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. To reheat, warm briefly in the microwave for 10-15 seconds or until soft but not melted.

FAQs
Can I use frozen raspberries for the swirl?
Yes, frozen raspberries work well. Just thaw them slightly and drain any excess liquid before cooking to avoid a runny swirl.
What if I don’t have parchment paper or foil to line the pan?
You can grease the baking pan thoroughly with butter or cooking spray, but lining helps in easy removal and cleaner slices.

- Preheat the Oven: Set your oven to 350°F (175°C) so it’s ready when batter preparation is complete.

Notes
- Ensure eggs are at room temperature for better emulsion and texture.
- Use high-quality semi-sweet chocolate chips for richer flavor and smoother melting.
- Swirling the raspberry sauce gently avoids mixing it completely into the batter, maintaining a beautiful marbled appearance.
- Cooling the brownies fully before slicing helps them set and makes cutting cleaner.
- Straining the raspberry sauce removes seeds for a smoother swirl texture.
