Ingredients You’ll Need

The beauty of these bars is in their simplicity; each ingredient is carefully chosen to contribute something distinct, whether that’s richness, texture, or gorgeous color. Don’t skip any step—every element plays its part in these unforgettable Chocolate Raspberry Crumb Bars.

• Unsalted Butter (16 tablespoons, 2 sticks): Brings richness and that classic, buttery crumb essential for the crust and topping.
• Light Brown Sugar (½ cup): Lends a hint of molasses sweetness that deepens the flavor of every bite.
• All-Purpose Flour (2 cups): The structural backbone for a tender, crumbly texture that holds everything together.
• Salt (½ teaspoon): Accentuates all the other flavors and cuts the sweetness just enough.
• Chopped Pecans or Walnuts (½ cup): Adds the perfect nutty crunch; toasting them first elevates their flavor even more.
• Sweetened Condensed Milk (14 ounces, 1 can): Makes the chocolate layer extra smooth, gooey, and rich.
• Bittersweet Chocolate Chips (1 cup): Forms the base chocolate layer, adding deep cocoa flavor that contrasts beautifully with raspberries.
• Raspberry Preserves (½ to ⅔ cup, seedless optional): Delivers that zingy, fruity tang—use seedless for a smoother finish or with seeds for extra texture.
• Semi-Sweet Chocolate Chips (1 cup): Scattered on top for melty, sweet surprises in every mouthful.

How to Make Chocolate Raspberry Crumb Bars

Step 1: Prep Your Pan

Preheat your oven to 350°F. Grab a 9×13-inch baking dish, lightly coat it with nonstick spray, and line it with parchment paper. This small prep step makes cleanup a breeze and ensures the bars lift out perfectly every time.

Step 2: Make the Buttery Crust

In a large mixing bowl—or the bowl of your stand mixer—cream together the softened butter and brown sugar for about 2 to 3 minutes until it’s fluffy, pale, and irresistible. Then add the flour and salt, mixing until you’ve got a crumbly dough. Set aside roughly ⅔ cup of this mixture; you’ll use it later for the crumb topping. Press the rest of the dough firmly and evenly into the bottom of your prepared pan for a nice even crust. This layer will be on the thinner side, just right for supporting everything else.

Step 3: Bake the Crust

Slide the pan into the oven and bake for about 10 minutes, until you spot just a touch of golden brown on the edges. This partial bake gives the base enough structure so it stays crisp under all the luscious layers to come.

Step 4: Mix Up the Crumb Topping

Take the reserved ⅔ cup of crust mixture and stir in the chopped pecans or walnuts. If you’ve toasted them first, you’ll be rewarded with a deeper nutty aroma and flavor that truly shines through as the crumb topping bakes.

Step 5: Make the Fudgy Chocolate Layer

In a microwave-safe bowl, combine the sweetened condensed milk with the bittersweet chocolate chips. Microwave in 30-second bursts, stirring each time until everything has just melted together into a smooth, glossy chocolate sauce. The condensed milk creates an unbelievably rich and creamy filling you’ll want to eat by the spoonful.

Step 6: Assemble the Chocolate Raspberry Crumb Bars

Pour the melted chocolate mixture evenly over your still-warm crust. Use an offset spatula or the back of a spoon to gently smooth the chocolate all the way to the edges, ensuring every single bite gets a bit of fudge. Sprinkle the nutty crumb topping right over the chocolate layer. Then, dollop teaspoonfuls of the raspberry preserves on top—if your preserves are a bit too thick, thin them out with a splash of water for easier spreading. Finish with a shower of semi-sweet chocolate chips scattered over everything.

Step 7: Bake and Cool

Bake the assembled bars for about 25 minutes, or until the top is just set and starting to turn golden. Don’t overbake; you want the middle to stay chewy and fudgy. Cool completely in the pan before slicing them into satisfyingly generous squares.

How to Serve Chocolate Raspberry Crumb Bars

Garnishes

There’s so much flavor here that these bars hardly need any extra adornment, but if you want to go the extra mile, a dusting of powdered sugar or a few fresh raspberries scattered across the top will make your Chocolate Raspberry Crumb Bars look as irresistible as they taste. For an ultra-decadent touch, add a light drizzle of melted white chocolate—or a dollop of freshly whipped cream for contrast.

Side Dishes

Pairing these bars with a scoop of vanilla or raspberry ice cream is the ultimate move if you want to dial up the indulgence. A cup of strong, hot coffee or a glass of cold milk also pairs beautifully, helping to balance the richness of the bars and cleanse your palate between bites.

Creative Ways to Present

These Chocolate Raspberry Crumb Bars make a stunning gift when cut into squares and packaged in a pretty box or tin—perfect for holidays or special occasions. Arrange them in a single layer on a platter with fresh berries and mint leaves tucked along the edges for a display that will get everyone talking. You can also cut them into smaller, bite-sized pieces and serve them as part of a dessert buffet.

Make Ahead and Storage

Storing Leftovers

Once completely cooled, the bars stay moist and chewy when stored in an airtight container at room temperature for up to four days. Make sure to place parchment or wax paper between layers if stacking, so they don’t stick together and each bar retains its crumbly top.

Freezing

To freeze, wrap each Chocolate Raspberry Crumb Bar individually in plastic wrap, then place them in a freezer-safe airtight container or zippered bag. They’ll keep well for up to two months. Thaw bars at room temperature for an hour or so before serving—this helps preserve both flavor and texture.

Reheating

If you’d like that melty chocolate magic all over again, try popping individual bars in the microwave for 10 to 15 seconds. This gentle warming revives their gooey center without baking them further—just be careful not to overheat, or the chocolate could seize. Warming also brings out the aroma of the nuts and raspberries in the most delightful way!

FAQs

Can I use a different type of berry preserve instead of raspberry?

Absolutely! While raspberry provides a fantastic contrast to the chocolate, you can swap in apricot, cherry, or blackberry preserves if you have a favorite. Just choose a good-quality preserve, and adjust the sweetness if necessary.

What’s the best way to cut the bars without making a mess?

For the cleanest slices, wait until the bars are fully cool (or even slightly chilled); then use a sharp knife wiped clean between each cut. Lining your pan with parchment helps to lift the entire slab out for neat, straight edges.

Can I make these Chocolate Raspberry Crumb Bars gluten-free?

Yes! Simply substitute a measure-for-measure gluten-free flour blend for the all-purpose flour. The recipe stays just as delicious and textured—no one will know the difference.

What if I don’t have bittersweet chocolate chips?

No worries—use semi-sweet chips instead, or even a chopped chocolate bar in a pinch. The flavor will be a little sweeter, but the bars will still impress. Try to use a chocolate labeled at least 60% cacao for that rich taste.

Do I need to toast the nuts first?

It’s optional but highly recommended! Toasted pecans or walnuts give a deeper flavor and crunch to the crumb topping, making each bite just that much more special. A quick 5 minutes in a 350°F oven is all it takes.

Final Thoughts

I hope you give these Chocolate Raspberry Crumb Bars a try soon—they’re one of those treats that make any ordinary day feel like a celebration.
