My son has an affinity for all things lemon. From lemonade to cream cheese lemon bars, and every lemon thing in between, he’ll gladly devour it. What does this have to do with these raspberry crumb bars? Well, not all of us love lemon as much as he does and we needed a break. 

I felt like it was my turn to choose dessert and the raspberries looked so good at the farmers market I couldn’t resist! And sometimes that’s just how a dessert is born.

How This Recipe Works

The reasons why this raspberry dessert works are simple, and so is the recipe! 

Whole raspberries — The combination of whole raspberries and raspberry preserves makes for the perfect sweet/tart flavor and texture. 

Crumb topping — Let’s face it, crumb bars aren’t complete without the crumb part right? This one is a winner with part butter, part sugar, plus flour and oats for crunch and texture. 

Simple instructions — In less than an hour you can put together the crust, filling, topped, and glazed and have it baked and cooled and in your belly. 

Customizable — No raspberries? No problem! You can substitute just about any berry you have on hand.

Here’s How You Make It

Go ahead and preheat your oven to 350 degrees, then line an 8×8-inch square baking pan with foil or parchment paper. 

Preparing the crust

  1. First, combine melted butter, sugar, and extract in a large bowl and stir. 
  2. Add the salt and flour to the butter mixture and stir again. 
  3. Finally, press the dough into your baking pan and put it in the oven for 10 minutes.

Preparing the filling

  1. For the filling, you’ll stir and gently mash half of the fresh raspberries into the raspberry preserves. 
  2. Take the crust out of the oven after 10 minutes. 
  3. Then, take the raspberry spread and put it on top of the prepared crust. Add to the top of the filling the rest of the fresh raspberries.ingredients for crumb topping in food processor

Preparing the crumb topping

  1. Now move on to topping by first dicing the chilled butter into small cubes.
  2. Next, in a medium bowl, stir together brown sugar, oats, flour, and salt. Add the butter and mash with a fork (or pulse in a food processor) until coarse crumbs form. Sprinkle the topping over filling.unbaked crumb topping in food processor

Bake and cool

  1. Put the whole dessert back into the oven for 25 minutes. Take the pan out of the oven and allow the raspberry crumb bars to cool before cutting them into squares. (You can pop it into the fridge to speed this up.)
  2. While the dessert is cooling, prepare the glaze by stirring together the powdered sugar, vanilla or almond extract, and enough milk to make the glaze easily pourable. Drizzle over cooled bars and serve.

Are You Supposed to Wash Raspberries?

There are two camps of thought on berry washing: wash and don’t wash. I am camp rinse (which I guess is halfway between the two?). I don’t use any special soap or fruit wash, but I do rinse them under cold water for a minute or so to get off surface dirt. I also always pat them dry because you won’t want that excess water in your dessert.

You can also soak them in a vinegar solution (¾ water and ¼ vinegar) before rinsing if you prefer. Still pat dry though after rinsing.

Expert Tips

I learned all the tricks of making this raspberry dessert the best it can be so you don’t have to!

  • If you are using a food processor to pulse together the crumb topping, be sure you don’t process it too much. You’ll still want to see (and taste) bits of whole oatmeal in the topping
  • If you think you’re going to want more than the 12-16 bars that this recipe will yield, you can easily double it and put it in a 9×13 pan. Just be sure to cook them an additional 5-10 minutes in the oven
  • Need to eat the berry bars ASAP? Put a towel under the hot baking dish and place it in the fridge to cool off faster. No need to reheat — they are amazing at room temperature or chilled.
  • While you don’t have to make the glaze, I think it adds a lot to the bars. Other glaze options include: a maple glaze, lemon glaze, or cream cheese icing.

Prep Time: 15 minutes
Cook Time: 35 minutes
Servings: 16 bars

Ingredients

Crust

  • 1 cup butter, melted
  • 1/2 cup sugar
  • 2 teaspoons almond or vanilla extract or 1 teaspoon of each
  • 1/2 teaspoon salt
  • 2 cup flour

Filling

  • 1 cup raspberry preserves
  • 1 cup fresh raspberries divided

Crumb topping

  • 8 tablespoons butter, chilled
  • 1/2 cup brown sugar
  • 1/2 cup old fashioned rolled oats
  • 3/4 cup flour
  • 1/4 teaspoon salt

Glaze

  • 1 cup powdered sugar
  • 1/2 teaspoon vanilla or almond extract
  • 3-6 tablespoons milk, as needed

Instructions

  • Preheat oven to 350 degrees and line an 8x8 inch square baking pan with foil or parchment paper.

Prepare the crust

  • In a large bowl combine melted butter, sugar, and extract. Stir together.
  • Add salt and flour and stir.
  • Press dough into prepared pan and bake for 10 minutes.

Prepare the filling

  • Stir and gently mash half of the fresh raspberries into the raspberry preserves.
  • Spread filling onto prepared crust. Top with remaining fresh raspberries.

Prepare the crumb topping

  • Dice the chilled butter into small cubes.
  • In a medium bowl stir together brown sugar, oats, flour, and salt. Add butter and mash with a fork (or pulse in a food processor!) til coarse crumbs form. Sprinkle over filling.

Finish it up

  • Bake for 25 minutes. Remove from oven and allow to cool before cutting into bars. (You can pop it into the fridge to speed this up).
  • While cooling, prepare the glaze by stirring together the powdered sugar, extract, and enough milk to make the glaze easily pourable. Drizzle over bars and serve.

Notes

  1. When made as written, this recipe makes 12-16 bars just depending on how large you cut the bars at the end. It can easily be doubled in a 9x13 pan for more bars (they'll be thicker and need 5-10 minutes longer in the oven). 
  2. If you're impatient, like me, you can pop the pan into the oven (place a dish towel underneath if the pan is still hot) to speed up the cooling process. Bonus: these taste AMAZING chilled! 
  3. The glaze is optional but definitely recommended - it just takes the whole dessert to the next level and looks super pretty!
  4. These bars would work great with blackberries or even a combination of both raspberries and blackberries.
