Ingredients

Scale

For the Crumb Layers:

  • 2 cup gluten free oats
  • 2 cups gluten free flour
  • 2 cups brown sugar
  • 1 cup butter (melted)
  • 1 tsp baking powder
  • 1 tsp salt

For the Blackberry Layer:

  • 4 cups blackberries (rinsed and drained) 
  • 1 lemon juiced
  • 1/4 cup white sugar
  • 2 tbsp corn starch 


Instructions

  1. Preheat your oven to 350. In a large mixing bowl, combine all ingredients for the crumb layers. Press 1/2 of the mixture into your baking dish (I used a 9×11). Pack it down to form the crust. 
  2. In a medium sized mixing saucepan, combine all ingredients for the berry layer. Mix well and simmer on low for 10 minutes until a smooth syrup begins to form around the berries. Pour this mixture over the oat crust and top with remaining oat mixture. 
  3. Bake for 45 minutes. Allow the bars to fully cool and harden before cutting into 12 bars and serving. Serving with vanilla ice cream optional but highly encouraged!
