Introduction

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 (for raspberry sauce)
- A small amount of water
Instructions
- Step 1: Line an 8-inch baking pan with parchment paper or foil, leaving overhang for easy removal. Lightly coat with cooking spray to prevent sticking.
- 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 becomes saucy. Mash the raspberries with a spoon or blend for a smoother sauce. Boil for a few minutes, then turn off the heat. Strain to remove seeds and set aside.
- Step 3: Preheat the oven to 350°F (175°C).
- Step 4: In a larger saucepan, melt butter and chocolate chips over low heat until smooth. Remove from heat and let cool. Refrigerate briefly to speed cooling if desired.
- Step 5: In a separate bowl, whisk eggs with 1 cup sugar and vanilla extract until well combined. Gradually add this egg mixture to the cooled chocolate mixture, stirring continuously to temper the eggs and avoid scrambling.
- Step 6: Add flour, salt, baking powder, and baking soda to the chocolate-egg mixture. Stir until smooth. Pour batter into the prepared pan and spread evenly. Spoon raspberry sauce over the top and gently swirl with a knife to create a marbled effect.
- Step 7: Bake for 30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Tips & Variations
- Use frozen raspberries if fresh aren’t available; just thaw before making the sauce.
- For extra texture, fold in chopped nuts like pecans or walnuts before baking.
- Try substituting semi-sweet chocolate chips with dark chocolate for a richer flavor.
- Let the brownies cool completely before slicing to keep the swirls defined.
Storage
Store brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate up to one week or freeze for up to 2 months. Reheat gently in the microwave or let come to room temperature before serving.

FAQs
Can I use frozen raspberries for the sauce?
Yes, frozen raspberries work well. Thaw them before cooking and proceed with the sauce as usual.
How do I know when the brownies are done?
Insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter. This ensures fudgy, not dry, brownies.

- 1/2 cup sugar

Instructions
- Prepare the Baking Pan: Line an 8-inch baking pan with parchment paper or foil, leaving an overhang for easy removal. Lightly coat the lining with cooking spray to prevent sticking.

Notes
- Use fresh or frozen raspberries for the sauce; if using frozen, thaw before cooking.
