Raspberry brownies bring together rich chocolate and bright berry flavor in the most delightful way. I remember the first time I swirled raspberry jam into brownie batter – it was a happy accident when I had leftover jam from Sunday breakfast, and my grandchildren declared it the best batch I’d ever made.
There’s something magical about watching those ruby-red raspberries sink into dark chocolate batter, their tartness cutting through all that fudgy richness. Growing up in my grandmother’s farmhouse kitchen, we’d pick wild raspberries from the bushes behind the barn, our fingers stained purple by the end of summer afternoons. She’d fold them into everything – pies, cobblers, and yes, even her chocolate squares. These raspberry brownies capture that same spirit of making the most of fresh fruit season, though I’ve simplified the recipe so you can have them on the table in about an hour. The jam swirls create the prettiest marbled effect, making them perfect for potlucks or when you want to impress without spending all day in the kitchen. Time to get our hands floury!
What Makes These Raspberry Brownies So Special
These raspberry brownies have become my go-to dessert when I need something impressive but don’t have hours to spare. Using a quality brownie mix as the base means you’re getting consistent results every time, while the fresh raspberries and jam add that homemade touch that makes people think you’ve been baking all day.

Ingredient Spotlight
Brownie Mix: I always choose a fudgy-style brownie mix rather than cake-style for these raspberry brownies, as the denser texture holds up better with the added moisture from the berries and creates that decadent, rich bite we’re looking for.
Fresh Raspberries: These delicate berries provide bursts of tart sweetness throughout the brownies and a beautiful visual contrast against the dark chocolate. I prefer fresh when they’re in season, but frozen raspberries work wonderfully too – just don’t thaw them before stirring into the batter.
Raspberry Jam: The jam creates those gorgeous marbled swirls and adds concentrated berry flavor that complements the fresh fruit. In my kitchen, I prefer a good-quality seedless jam for the smoothest texture, though seeded varieties work just fine if that’s what you have.
Eggs, Oil, and Water: These standard brownie mix ingredients create the structure and moisture needed for that perfect fudgy texture. I’ve learned that following the box directions exactly gives you the most reliable results.
How to Make Raspberry Brownies
Step 1: Betty always starts by preheating the oven according to the brownie box directions for an 8×8-inch pan (usually 325-350°F) and generously spraying the pan with non-stick spray. This ensures your beautiful raspberry brownies lift out cleanly after baking.
Step 2: Prepare your boxed brownie mix following the package directions exactly, mixing until the batter is smooth and well-combined. I’ve found that over-mixing can make brownies tough, so stop as soon as you no longer see dry ingredients.
Step 3: Gently fold one cup of raspberries into the brownie batter using a spatula, being careful not to crush them too much. A few broken berries are fine and actually help distribute that raspberry flavor throughout.
Step 4: Pour the raspberry-studded batter into your prepared pan and use a spatula to spread it evenly into the corners. The batter should be fairly thick and hold those berries suspended beautifully.
Step 5: Drop the two tablespoons of raspberry jam in small dollops across the top of the batter, spacing them evenly. I like to use about 5-6 dollops rather than just two big globs for better distribution.
Step 6: Take the tip of a butter knife and gently swirl the jam through the top layer of batter in a figure-eight or zigzag pattern. After years of making these, I learned that you don’t want to swirl too deeply or too much, just enough to create those pretty marbled streaks.
Step 7: Press additional whole raspberries gently into the top of the batter for that bakery-worthy presentation. These berries will create beautiful jammy spots as they bake and make your raspberry brownies look stunning.
Step 8: Bake according to the box directions, usually 28-33 minutes for an 8×8 pan, checking with a toothpick inserted about 2 inches from the edge. It should come out with a few moist crumbs but not wet batter. Remember that these raspberry brownies will continue to set as they cool.
Keeping These Raspberry Brownies Fresh
I typically store leftover raspberry brownies in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. The fridge storage is actually my preference with these because the fresh raspberries stay fresher longer, though you’ll want to bring them closer to room temperature before serving for the best fudgy texture.
Betty’s freezing method works wonderfully for these raspberry brownies. Cut them into squares, wrap each piece individually in plastic wrap, then place them all in a freezer-safe container or bag. They’ll keep beautifully for up to 3 months this way. My grandchildren love finding individually wrapped brownies in the freezer for quick after-school treats.
For the best texture when enjoying refrigerated brownies, I let them sit at room temperature for about 15-20 minutes before serving. If you’re reheating frozen brownies, thaw them overnight in the refrigerator, then warm individual pieces in the microwave for about 10-15 seconds – just enough to bring back that fresh-from-the-oven softness without melting the chocolate completely.
Perfect Partners for Raspberry Brownies
- Vanilla Ice Cream: The cold, creamy sweetness creates a magnificent contrast with warm, fudgy raspberry brownies, and watching that ice cream melt into the chocolate is pure dessert heaven.
- Fresh Whipped Cream: A simple dollop of lightly sweetened whipped cream adds elegance without overwhelming the berry-chocolate flavor combination, making these suitable for fancier gatherings.
- Hot Coffee or Cold Milk: Betty always served her chocolate desserts with strong coffee for adults and cold milk for the kids. Both drinks cut through the richness perfectly and make this feel like a complete dessert experience.
- Blueberry Cream Cheese Croissant Casserole: For a berry-themed brunch spread, pair these chocolate raspberry brownies with this fruity breakfast casserole to offer both sweet morning and dessert options.
- Cranberry Brie Bites: When entertaining, serve these elegant appetizers alongside raspberry brownies for a complete sweet-and-savory party spread.
- Banana Cream Pie Overnight Oats: Balance a decadent brownie dessert with a lighter breakfast option that still satisfies your sweet tooth.
FAQs
I recommend using frozen raspberries straight from the freezer without thawing. They work beautifully and won’t make the batter too wet, though you might need to add an extra minute or two to the baking time.
To prevent this issue, make sure you’re using an 8×8-inch pan as specified and testing for doneness about 2 inches from the edge rather than the very center. The residual heat will finish cooking the middle as they cool, and overbaking creates dry, cakey brownies.
Betty’s solution is to bake them the day before your event, let them cool completely, then cover tightly and store at room temperature. They actually taste even better the next day once the flavors have melded together.
