Step‑by‑Step Instructions for Raspberry Swirl Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms, prepare a 9x13 inch baking pan by greasing it lightly and lining it with parchment paper. This will ensure your raspberry swirl brownies release easily after baking and allow for easy cleanup.
Step 2: Melt the Butter
In a medium saucepan over low heat, melt 1 cup of unsalted butter. Once fully melted, remove the saucepan from the heat and stir in 2 cups of granulated sugar until well combined. This mixture will create the rich foundation for your brownies, so be sure it's nicely blended before moving on.
Step 3: Add Eggs and Vanilla
Now it’s time to enrich the butter mixture! Add 4 large eggs to the saucepan, one at a time, stirring well after each addition. This ensures that each egg is fully incorporated. Next, mix in 1 teaspoon of vanilla extract for that warm, aromatic flavor that complements the chocolate.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, 1 cup of unsweetened cocoa powder, ½ teaspoon of salt, and ½ teaspoon of baking powder. This dry mix adds structure and the deep chocolate flavor that defines your raspberry swirl brownies. Make sure there are no lumps for a smooth batter.
Step 5: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the butter mixture, stirring gently until just combined. Be cautious not to overmix; you want the brownies to stay fudgy. The batter will be thick and luscious, ready to transform into mouthwatering raspberry swirl brownies.
Step 6: Prepare the Raspberry Puree
For the raspberry swirl, blend 6 oz of fresh raspberries with 2 tablespoons of granulated sugar and 1 tablespoon of lemon juice in a blender until smooth. This vibrant puree will add a burst of tangy flavor and stunning color. Strain the mixture through a fine-mesh sieve to remove any seeds for a silky texture.
Step 7: Assemble the Brownie Batter
Pour the brownie batter into your prepared baking pan, spreading it out evenly using a spatula. This will serve as the base for your raspberry swirl brownies. Ensure the layer is smooth and even to promote consistent baking throughout.
Step 8: Swirl in Raspberry Puree
Using a spoon, drop dollops of the raspberry puree onto the top of the brownie batter. Carefully use a knife or toothpick to swirl the puree into the batter, creating a beautiful marbled effect. This step adds both visual appeal and delicious flavor to your raspberry swirl brownies.
Step 9: Bake the Brownies
Place the baking pan in the preheated oven and bake for 30–35 minutes. The edges should look set, and a toothpick inserted into the center should come out with a few moist crumbs, indicating the brownies are perfectly fudgy and ready to cool.
Step 10: Cool and Slice
Once baked, remove the brownies from the oven and let them cool in the pan on a wire rack for at least 10 minutes. After they’ve cooled, slice into squares and serve. These raspberry swirl brownies are sure to impress with their delicious blend of flavors and beautiful presentation!

How to Store and Freeze Raspberry Swirl Brownies
