Decadent Chocolate Raspberry Crumb Bars

Hello lovely bakers! I’m Meriem, your pastry-loving recipe developer and baking cheerleader-and today, I’m thrilled to share one of my all-time favorites: ๐Ÿ‡๐Ÿซ Decadent Chocolate Raspberry Crumb Bars!

These bars are a dreamy blend of textures: crisp and buttery on the outside, soft and jammy on the inside, with melty dark chocolate in every bite. They remind me of the first time I brought these to a brunch gathering and every guest asked for the recipe (yes, even the ones who โ€œdon’t eat sweetsโ€!).

If you’ve adored my Berry Oat Breakfast Bars or my Chocolate Chip Cookie Bars, this one will fit right into your dessert-loving soul.


Why You’ll Love This Recipe

  • ๐Ÿซ Decadent but easy – Made with pantry staples and ready in under an hour.
  • ๐Ÿงˆ Buttery crumb base & topping – Golden and crisp with just the right chew.
  • ๐Ÿ‡ Sweet & tart combo – Raspberry and chocolate = ultimate pairing.
  • ๐Ÿช Perfect for sharing – Cut into 12 bars, ideal for gifting or parties.
  • ๐Ÿ’ก Customizable – Easily swap preserves or chocolate types.

What You’ll Need

  • ๐ŸŒพ 1ยฝ cups all-purpose flour (180g) – The base of the crumb, creating structure. Sub with gluten-free 1:1 blend if needed or half whole wheat flour (may be denser).
  • ๐Ÿฅฃ ยฝ cup rolled oats (45g) – Adds texture and nuttiness. Use quick oats for a finer crumb.
  • ๐Ÿฌ ยฝ cup granulated sugar (100g) – Sweetens the base and topping. Coconut sugar works as a natural substitute.
  • ๐Ÿงˆ ยพ cup unsalted butter (170g), chilled and cubed – Key for that melt-in-your-mouth crumb. Vegan butter or coconut oil works in a pinch.
  • ๐Ÿง‚ ยผ tsp salt – Balances the sweetness and enhances flavor.
  • ๐Ÿซ 1 cup dark chocolate chips (175g) – Use semi-sweet or milk chocolate if preferred. For dairy-free, choose vegan chocolate chips.
  • ๐Ÿ‡ 1 cup raspberry preserves (300g) – The gooey, fruity center. Can be swapped with strawberry, blackberry, or apricot jam.
  • ๐Ÿฅ„ ยฝ tsp vanilla extract – Adds aromatic depth. Optional but lovely.

Equipment Needed

  • โœ… Mixing bowls (1 large, 1 small)
  • โœ… Pastry cutter or fork (for cutting butter)
  • โœ… 8×8-inch baking pan
  • โœ… Parchment paper
  • โœ… Spatula or offset knife
  • ๐Ÿง Optional: Cooling rack for faster setting

Step-by-Step Instructions

Preheat & Line

Preheat your oven to 350ยฐF (175ยฐC). Line an 8×8-inch baking pan with parchment paper, leaving a little overhang for easy removal.

๐Ÿ’ก Meriem’s tip: Lightly butter the pan before adding parchment to help it stick flat.

Make the Crumb Mixture

In a large bowl, combine 1ยฝ cups flour, ยฝ cup oats, ยฝ cup sugar, and ยผ tsp salt. Cut in ยพ cup chilled butter and ยฝ tsp vanilla extract using a pastry cutter or fork until coarse crumbs form.

๐Ÿ’ก Pro tip: Don’t overwork the butter-chunks mean flakier texture!


Create the Base

Press two-thirds of the crumb mixture firmly into the bottom of your pan to create a solid crust.

Add Filling

Spread 1 cup raspberry preserves evenly across the base. Sprinkle 1 cup chocolate chips over the preserves.

๐Ÿซ Optional upgrade: Add chopped toasted almonds or hazelnuts with the chocolate!

Top & Bake

Crumble the remaining oat mixture evenly over the top. Bake for 30-35 minutes, or until the topping is golden brown and the center is bubbling slightly.

Cool & Slice

Let cool in the pan for at least 1 hour. Remove using parchment overhang and slice into 12 even bars.

๐Ÿ’ก Chill in fridge for cleaner cuts if gifting or packing.

    These are so good! Very easy and delicious. I accidentally forgot the vanilla and they were still amazing. Absolutely making these again. Definitely a keeper! Kind of reminds me of butter cookie from the bakeryโ€ฆthe sandwich kind with raspberry filling dipped in chocolate. Yum!!!
