What do you need to make Blueberry Crumb Bars?

Nonstick Cooking Spray – Of course, this is so you can get the blueberry bars out in one piece instead of a broken mess. So don’t skip this ingredient!

Rolled Oats – For best results, use minute-oats instead of old-fashioned oats. The texture will be much more pleasant.

Flour – We use a combination of wheat flour and all-purpose flour in these yummy blueberry bars.

Brown Sugar – The sweetness comes from the packed brown sugar in this recipe.

Apple Pie Spice – Using apple pie spice takes this recipe to an entirely new level of amazing. It’s the perfect amount too.

Butter – The butter is essential to bring the ingredients together correctly.

Slivered Almonds – I love having a little bit of a crunch in my blueberry muffin bars, and almonds give me the right amount of crispy goodness.

Blueberry Preserves – The preserves are where you get all the sweet blueberry flavor from.

Almond Extract – I may be addicted to using almond extract! It gives you a light almond flavor that’s not overwhelming or strong.

How To Make Blueberry Crumb Bars

  • Warm up the oven to 350 degrees, and line a baking pan with foil.
  • Make sure you let the foil extend up over the edges. This will make it easier to get the blueberry bars out.
  • Lightly spray the aluminum foil with cooking spray.
  • Mix the oats, both kinds of flour, brown sugar, and apple pie spice in a large bowl.
  • Take a pastry blender and add in the butter.
  • Mix until the mixture becomes crumbly.
  • Add ¾ cup of the crumb mixture to a bowl and fold in the almonds.

Take the rest of the blueberry crumb mixture and press it into the bottom of the pan. Bake the crumb crust for 10 minutes.

  • Combine the blueberry preserves and almond extract in a bowl. Then spread the mixture on top of the crumb crust. Add the reserved almond crumb crust on top and slightly press it down.

  • Bake the blueberry bars for 20 – 25 minutes. The top will be golden brown when done. Let it cool on a wire rack. After the bars are cool, lift up the foil pieces and cut them into evenly shaped bars.

What is the Best Way to Store Blueberry Crumb Bars?

Wrap up each of the blueberry crumb bars in pieces of aluminum foil. You can add them to another container or ziplock bag if you want, but it’s not required. Keep them in the pantry or in the fridge, depending on your preference.
