Understanding the Key Ingredients

Let’s break down the essential components that make these bars both tasty and nutritious!

Blueberry Filling Ingredients

  • 2 cups frozen blueberries (defrosted)
  • 2 teaspoons corn starch
  • 1 tablespoon lemon juice
  • ¼ cup Splenda or white granulated sugar/sweetener

Bottom Layer and Crumble Topping Ingredients

  • 1 ¼ cup flour
  • ½ cup Splenda or white granulated sugar/sweetener
  • ¼ teaspoon baking powder
  • ½ cup plain Greek yogurt
  • 1 large egg
  • 1 tablespoon brown sugar
  • ½ cup quick oats

Step-by-Step Baking Instructions

  1. Preheat your oven to 375°F. Grease an 8×8 square baking dish and line it with parchment paper, leaving a 3-inch overhang.
  2. In a medium bowl, combine sweetener, flour, and baking powder. Mix with a fork until well combined.
  3. Add Greek yogurt and egg to the dry mixture. Mix until crumbly and well incorporated.
  4. Press about ¾ of the crumbly mixture into the bottom of the prepared dish to form an even layer. Set aside the remainder.
  5. In another bowl, mix the defrosted blueberries with corn starch, lemon juice, and sweetener. Pour this mixture evenly over the base layer.
  6. Stir in brown sugar and quick oats into the reserved crumbly mixture. Mix until crumbly.
  7. Sprinkle the oat mixture generously over the blueberry layer.
  8. Bake for 45 minutes or until golden brown.
  9. Allow the bars to cool completely in the refrigerator for about 2-3 hours before cutting into portions.
  10. Use the parchment paper overhang to lift the bars from the dish and cut them into squares.

Tips for Perfect Crumble Bars

For the best results, ensure your blueberries are well-drained after defrosting. You can also experiment with different sweeteners to suit your taste! Remember, patience is key; allowing the bars to cool fully helps them set and enhances their texture.

Enjoy these blueberry oat crumble bars chilled or at room temperature. They store wonderfully in an airtight container in the refrigerator for up to a week, making them a great option for meal prep!
