About this recipe

This recipe makes soft oat crumb bars with dark chocolate and fresh raspberries. You will get a mix of sweet chocolate and bright fruit in each bite. If you like rich treats, you may also enjoy a dark chocolate ganache tart for a change.

why make this recipe

Make these bars when you want a quick sweet that feels special. You can make them in one pan and share with friends. This treat works well for snack time, dessert, or a small party. For other easy fruit bars, see the apple crumble coffee cake for more ideas.

how to make Dark Chocolate Raspberry Oatmeal Crumb Bars

Make the crust and the top from the same oat mix. Press half the mix into the pan for the base. Add fresh raspberries and dark chips on top. Then add the rest of the crumbs and bake. These steps keep the bars crumbly and full of flavor. If you like very rich chocolate, think of a double chocolate cake as another bake to try.

Ingredients :

1 cup rolled oats
1 cup all-purpose flour
1/2 cup brown sugar
1/2 cup unsalted butter, melted
1/2 teaspoon salt
1 cup fresh raspberries
1/2 cup dark chocolate chips
1 tablespoon lemon juice

You might use some browned butter for a nutty note, as in this brown butter banana bread idea.

Directions :

Preheat oven to 350°F (175°C). Grease an 8×8 inch baking dish.
In a bowl, mix oats, flour, brown sugar, melted butter, and salt until crumbly.
Press half of the mixture into the bottom of the prepared baking dish.
Spread raspberries and dark chocolate chips evenly over the crust. Drizzle with lemon juice.
Sprinkle the remaining crumb mixture on top.
Bake for 25-30 minutes or until golden brown.
Allow to cool before cutting into bars.

FAQs

Q: Can I use frozen raspberries?
A: Yes. Thaw and drain them a bit so they do not make the bars too wet.

Q: Can I cut the sugar?
A: You can use a little less brown sugar, but the bars will be less sweet and less brown.

Q: Can I make this in a larger pan?
A: Yes. Use a larger pan and bake a few minutes less. Watch the top for color.

Q: How do I stop the chocolate from melting into the fruit?
A: Add the fruit first and the chips on top. This helps the chips keep their shape.
