Can I use frozen raspberries instead of fresh?

Absolutely. Thaw them first and simmer as directed; just know they may release a bit more juice, so simmer longer if needed to get a thick, jammy consistency.

What’s the best way to slice the fudge cleanly?

For neat squares, use a sharp knife dipped in hot water and wiped clean between cuts. This helps glide through the chilled fudge without cracking.

Can I make this recipe vegan?

Yes! Use vegan chocolate chips or bars and make sure your nut or seed butter doesn’t contain any added dairy.

Can I double the recipe for a crowd?

Definitely. Double all the ingredients and use an 8x8-inch baking pan for more pieces. The method stays exactly the same.

Ingredients You’ll Need

Fresh Raspberries: For the bright, punchy fruit swirl. Frozen berries work in a pinch, but fresh give the best flavor and texture.
Dark Chocolate Chips or Bar: The heart and soul of the fudge. Use a good-quality bar for the most luxurious melt.
Unrefined Organic Coconut Oil: Helps the chocolate melt silky-smooth and keeps the finished fudge firm but sliceable.
All-Natural Peanut Butter (or Any Nut/Seed Butter): Adds creaminess and richness. Almond butter, cashew butter, or sunflower seed butter are all great choices.
Flaky Sea Salt (optional): For a finishing touch that makes all the flavors sing. Highly recommended for a gourmet feel!

Note: Not a fan of dark chocolate? Milk or even white chocolate can work, just be aware the fudge will be sweeter.

Variations

Nut-Free: Swap peanut butter for sunflower seed or tahini for a nut-free treat.
Berries: Try blackberries, strawberries, or a mix of berries for new flavor twists.
Chocolate Choices: Go for extra-dark (70%+), smooth milk chocolate, or even half-and-half for layers of flavor.
Toppings: Add chopped roasted nuts, shredded coconut, or a sprinkle of freeze-dried raspberries on top before chilling.

How to Make Raspberry Swirl Fudge

Step 1: Prep Your Pan

Line a loaf pan with parchment paper so you can lift out the fudge easily for slicing.

Step 2: Make the Raspberry Swirl

Place fresh raspberries in a small saucepan over medium heat. Crush lightly with a fork and simmer for about five minutes until jammy, stirring occasionally. Set aside to cool a bit.

Step 3: Melt the Chocolate

Create a double boiler by bringing water to a low simmer in a medium saucepan. Reduce to LOW heat, then set a heatproof bowl over (not touching) the water. Add dark chocolate and coconut oil, whisking until just melted and smooth.

Step 4: Stir in Nut Butter

Add your peanut butter (or nut/seed butter of choice) to the melted chocolate. Stir or whisk until the mixture is creamy and totally blended.

Step 5: Assemble and Swirl

Pour the chocolate mixture into your prepared pan and smooth the top. Dollop spoonfuls of the raspberry mixture over the surface, then gently swirl with a toothpick for a pretty marbled effect.

Step 6: Add Toppings (Optional)

Sprinkle a little flaky sea salt on top for contrast and extra flavor.

Step 7: Chill and Slice

Refrigerate the fudge for at least two hours to set. Lift out, slice into bite-size squares, and enjoy!

Pro Tips for Making the Recipe

Don’t Rush the Swirl: Swirl gently so you get beautiful streaks—not blended pink fudge.
Chill Thoroughly: Resist slicing too soon—the fudge needs time to firm up for perfect pieces.
Use Good Chocolate: Since chocolate is front and center, splurge for a bar or chips you’d happily eat on their own.
Customize the Nut Butter: Don’t hesitate to try cashew or almond butter if peanut isn’t your favorite.

How to Serve

This fudge is decadent enough to stand alone, but here are some serving ideas:

Simple Slices: Serve cold, straight from the fridge, for the creamiest bite.
Dessert Platter: Add fruit, other chocolates, or cheese for an elegant dessert board.
Paired with Coffee or Tea: The tart raspberry and rich chocolate taste incredible alongside a dark roast or your favorite afternoon tea.
Gift Giving: Wrap individual squares in wax paper or a small box for a homemade edible gift.

Make Ahead and Storage

Storing Leftovers

Wrap leftover fudge pieces tightly and store in an airtight container in the fridge. They stay fresh and perfect for up to one week.

Freezing

Freeze extra pieces for up to two months. Place parchment between layers to prevent sticking. Thaw in the fridge before enjoying.

Reheating

No reheating is needed! This fudge is meant to be served chilled—just let it sit at room temperature for a few minutes if you prefer a softer bite.
