Why Should You Make This Recipe

If you enjoy rich, fudgy brownies with a twist, these raspberry brownies are worth trying. They combine classic chocolate depth with the bright acidity of raspberries for a multi-layered dessert experience. Highlights of this recipe:

  • Deep, fudgy texture. The brownies are dense and chocolate-forward, with a moist center and slightly crisp edges.
  • Simple to prepare. The method follows basic brownie steps: melt butter and chocolate, mix wet and dry ingredients, fold in raspberries, bake, and chill.
  • Fresh fruity contrast. Raspberries add a tart, juicy balance to the sweet chocolate, creating a lively flavor contrast.

Ingredients

Before you start, gather the following ingredients:

Gather butter, chocolate chips, espresso powder, eggs, sugar, light brown sugar, vanilla extract, salt, cocoa powder, flour and raspberries.

Unsalted butter, chocolate chips, espresso powder, eggs, granulated sugar, light brown sugar, vanilla extract, salt, Dutch-process cocoa powder, all-purpose flour, and fresh or frozen raspberries.

Substitutions

These swaps work well if you need them:

  • Chocolate chips: Any semi-sweet or dark chocolate works fine.
  • Butter: Unsalted sweet cream butter is recommended; use salted and reduce added salt if preferred.
  • Sugars: Granulated and light brown sugar give the best texture; for refined-sugar-free options, consider natural alternatives but expect slight texture differences.
  • Eggs: Eggs are essential for the fudgy structure; the recipe hasn’t been tested without them.
  • Cocoa powder: Unsweetened or Dutch-process cocoa both work, with Dutch offering a rounder chocolate flavor.
  • Flour: For gluten-free brownies, use a reliable 1:1 gluten-free flour by weight (about 90 g for this recipe).
  • Raspberries: Fresh raspberries are best. If using frozen, toss them in 1 tablespoon of flour and add them straight from frozen to the batter.

Variations

  • Box mix shortcut: For a 9 x 9 pan, use one family-size box mix and fold in 1 cup raspberries before baking.
  • Almond flour version: Use an almond flour brownie base and fold in raspberries for a grain-free option.
  • Raspberry jam swirl: Dollop warmed raspberry jam on top of the batter and swirl before baking for a glossy jam ribbon.

How To Make

Follow these straightforward steps to make raspberry brownies.

Melt butter and chocolate, whisk the wet ingredients, combine dry ingredients, fold in raspberries and bake.
  1. Preheat and prepare: Heat the oven to 350°F (177°C). Line a 9 x 9-inch pan with parchment, leaving an overhang for easy removal.
  2. Melt chocolate and butter: In a microwave-safe bowl, combine cubed butter and 1 cup of chocolate chips. Heat in 30-second bursts, stirring between each, until fully melted. Stir in the espresso powder and set aside.
  3. Mix wet ingredients: In a separate bowl whisk together eggs, granulated sugar, light brown sugar, vanilla, and salt until smooth. Whisk in the melted chocolate mixture until uniform.
  4. Add dry ingredients: Whisk in cocoa powder, flour, and the remaining chocolate chips until the batter is glossy and even. Gently fold in the raspberries until just incorporated.
  5. Bake: Spread the batter evenly into the prepared pan. Bake 25–30 minutes if using fresh raspberries, or up to 35 minutes if using frozen. Look for set edges that pull slightly from the pan and a few moist crumbs on a toothpick inserted in the center.
  6. Cool and chill: Let the brownies cool at room temperature for 1 hour, then cover and chill in the refrigerator for 1–2 hours to fully set. Use the parchment overhang to lift the brownies from the pan, slice, and serve.

How To Serve, Store, Freeze and Thaw

  • Store: Keep cooled brownies in an airtight container in the refrigerator for up to 5 days.
  • Freeze: Cut into portions and wrap individually in plastic wrap, then place in a freezer-safe bag for up to 2 months. To freeze a whole pan, wrap tightly and place in a freezer-safe container.
  • Thaw: Thaw overnight in the refrigerator for the best texture and flavor.

M’s Expert Tips

  • Bring ingredients to room temperature: This helps them combine smoothly and reduces mixing, keeping the brownies fudgy. Frozen raspberries can be added straight from the freezer (toss in a little flour first).
  • Prefer metal pans: The recipe was developed for a 9 x 9-inch aluminum pan. If using glass, reduce oven temperature to 325°F (163°C) and monitor baking time closely.
  • Use parchment: Lining the pan with parchment makes removal effortless; alternatively, lightly grease the pan.
  • Don’t overbake: The center should have moist crumbs on a toothpick, not wet batter. Edges will look set and may pull away slightly.
  • Chill for clean slices: Cooling and chilling fully helps with neat cutting. Wipe your knife between slices for the best presentation.

FAQs

What are raspberry brownies?

Raspberry brownies are fudgy chocolate brownies with raspberries folded into the batter, giving each bite a burst of tart fruitiness alongside rich chocolate.

Can I make this in a different pan size?

Yes. To bake in a 9 x 13-inch pan, increase the recipe by about 1.5 times and adjust baking time as needed.

Can raspberry brownies be left out?

Because these brownies contain fruit, it’s best to store them refrigerated rather than at room temperature to maintain freshness.
