Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 cup (170g) semi-sweet chocolate chips
1/2 cup (115g) unsalted butter
1 cup (200g) granulated sugar
2 large eggs
1 teaspoon vanilla extract
2/3 cup (85g) all-purpose flour
1/4 teaspoon salt
1/4 cup (25g) unsweetened cocoa powder
1/2 cup (150g) raspberry jam
1/4 cup (30g) fresh raspberries (optional, for added texture and flavor)

Directions

I start by preheating the oven to 350°F (175°C) and lining an 8×8-inch baking pan with parchment paper.
In a medium saucepan over low heat, I melt the butter and chocolate chips together, stirring until smooth.
I remove the pan from heat and whisk in the sugar until fully combined.
Then, I add the eggs one at a time, followed by the vanilla extract, mixing well after each addition.
I sift in the flour, cocoa powder, and salt, and stir until just combined—being careful not to overmix.
I pour the brownie batter into the prepared pan and smooth the top.
I warm the raspberry jam slightly (just a few seconds in the microwave), then drop spoonfuls over the batter. Using a knife or skewer, I gently swirl the jam through the batter.
If I’m using fresh raspberries, I scatter them over the top.
I bake the brownies for 30–35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
I let them cool completely in the pan before slicing.

Servings and timing

This recipe makes 9 large brownies or 16 smaller squares. I usually bake them for about 30–35 minutes. Prep time is around 15 minutes, and cooling takes about 1 hour.

Variations

I sometimes swap the raspberry jam for strawberry or cherry for a different fruity twist.
For extra indulgence, I stir in white chocolate chips or chopped nuts into the batter.
I’ve also made these with a gluten-free flour blend, and they turn out beautifully with just a slight texture difference.

Storage/Reheating

I store these brownies in an airtight container at room temperature for up to 3 days. For longer storage, I keep them in the fridge for up to a week. They also freeze well—I wrap them individually and freeze for up to 2 months. To enjoy, I let them thaw at room temperature or microwave for about 10–15 seconds for a warm treat.

FAQs

How do I get the perfect swirl on top?

I warm the jam slightly and use a toothpick or knife to gently swirl it through the batter. I try not to overdo it so the pattern stays defined.

Can I use frozen raspberries?

Yes, but I always thaw and drain them first to avoid excess moisture in the batter.

Can I double the recipe?

Absolutely. I double all ingredients and bake in a 9×13-inch pan. The baking time increases slightly—around 40–45 minutes.

What kind of cocoa powder works best?

I prefer unsweetened natural cocoa powder for its strong chocolate flavor, but Dutch-processed can be used for a richer taste.

How do I know when the brownies are done?

I look for a slightly firm top and a toothpick that comes out with a few moist crumbs—not wet batter.

Conclusion

These decadent raspberry swirl brownies bring together rich chocolate and bright berry flavor in the most satisfying way. I find them perfect for when I want to bake something a little special without a ton of effort. The balance of flavors, gorgeous appearance, and satisfying texture make them a go-to favorite in my kitchen.
