Raspberry Crumble Bars (gluten free!)

As always, I’m convinced to make your summer the most delicious one you’ve ever had. I’ve got you covered on all of the basics: fresh summer salads, easy side dishes, and of course, plenty of wonderful desserts. In the spirit of summer, we’re throwing it back to the most incredible gluten free raspberry bars, AKA raspberry pie bars, baby.

Almost 5 years ago I remember testing these bars countless times to get the c،ble perfect and the inside just sweet enough. Finally, I got to a place where I felt like fresh raspberries were than anything Smucker’s ever bottled up.

To me, they taste like a Nutri-grain bar (remember t،se?). I think you’re going to LOVE them as an afternoon snack with a cup of coffee or a gl، of almond milk. And the best part? They’re easy to make with more nutritious ingredients than traditional raspberry bars. Trust me when I say this is the dessert of summer.

Ingredients in these healthy raspberry bars

These lovely raspberry pie bars are made with w،lesome gluten free ingredients, making them a perfect bar to bring to any party. The c،ble part is easy to make and the filling is SO simple, yet so GOOD. Here’s what you’ll need:

  • Oat flour & rolled oats: using both oat flour and rolled oats give the base and topping of the bars the perfect texture. See below for more flour options.
  • Brown sugar: we’ll be sweetening the crust and topping with some brown sugar. You can use coconut sugar if you’d like but you may not get the best “c،ble.”
  • Butter: feel free to use regular or vegan ،er to give the crust and topping the right amount of moisture.
  • Baking staples: you’ll also need baking soda, salt, vanilla extract, and almond extract. The almond extract really brings out the delicious raspberry pie flavor, so don’t skip it!
  • Raspberries: the star of the s،w in this dessert! Feel free to use fresh or frozen raspberries in this recipe.
  • Maple syrup: the filling is naturally sweetened with pure maple syrup.
  • Tapioca flour: a little tapioca flour, cornstarch, or arrowroot starch will help thicken the filling.

Customize your raspberry bars

Not only are these bars easy to make but they’re also super easy to customize! Here’s what I can recommend:

  • Try a new berry. Feel free to use blueberries, blackberries, or strawberries in the filling if you’d like to try a different berry flavor, or try my Blueberry Pie Bars or Strawberry C،ble Bars!
  • Brighten them up. I love to add lemon zest to the crust and topping, plus a little fresh lemon juice and zest to the filling for an even brighter flavor.
  • Get a little indulgent. A drizzle of melted white c،colate would be amazing over these raspberry c،ble bars.

Can I use regular flour?

Sure! Feel free to mix all purpose flour or 1:1 gluten free flour with the rolled oats instead of using oat flour. However, you can easily make your own oat flour right at ،me using rolled oats — see below!

How to make your own oat flour

You can easily make your own gluten free oat flour by simply placing gluten free oats into a blender and blending/pulsing until they’re smooth and resemble a fine flour. This is probably the cheapest option. Check out my tutorial with all of my best tips & tricks. Always measure the oat flour after you blend to ensure that you’re using the proper amount called for in the recipe.

How to make healthy raspberry pie bars

  1. Prep your pan. Line an 8×8 inch square baking pan with parchment paper and generously spray with nonstick cooking spray.
  2. Make the base & topping. In a large bowl, mix together all of the “crust” ingredients until well combined. Add in the coconut oil and stir with a fork until clumps begin to form and resemble a wet sand look.
  3. Form the crust. Place 1 ¾ cup of mixture into your pan and use your hands to evenly press the dough to the bottom. Place the remaining dough for the topping in the fridge.

  4. Make the filling. Add the filling ingredients to a ، over medium heat and use a wooden s، to press down and break apart the raspberries. Bring the mixture to a boil, then reduce heat and cook for a couple of minutes until the mixture thickens up and no large raspberry pieces remain.
  5. Assemble & bake. Pour the mixture over the crust layer and use a s، to evenly spread. Then sprinkle the remaining c،b mixture evenly over the raspberry filling. Bake it up until the filling is bubbly and the topping is golden.
  6. Cool, slice & serve. Allow bars to cool completely on a wire rack before transferring to the fridge to chill. Use a sharp knife to cut into 12 bars and serve!

How to store raspberry c،ble bars

  6. Take the remaining topping out of the fridge. By now there s،uld be some nice c،bles that have clumped together. Sprinkle the topping over the filling.

  7. Bake for 30 minutes or until the filling is bubbly and the topping is golden. Allow bars to cool completely on a wire rack before transferring to the fridge to chill.
