Ingredients

  • 1 ½ c quick oats
  • 1 ½ c flour
  • 1 c brown sugar, lightly packed
  • 1 c butter, melted
  • 1 ½ tsp cinnamon
  • 1 tsp vanilla extract
  • ½ tsp baking powder
  • ½ tsp sea salt
  • 2 ½ c mixed berries, fresh or frozen (thawed if frozen)
  • Juice of 1/2 lemon
  • 1 tsp corn starch
  • 3 T sugar (more if berries are super tart)

Instructions

  • Preheat oven to 350°F.
  • In a bowl, mix together sugar, lemon juice, berries and corn starch and mix to combine. Set aside.
  • In a separate bowl, combine oats, flour, brown sugar, cinnamon, sea salt, and baking powder and whisk together.
  • Add in melted butter and vanilla and stir to combine. Mixture will be somewhat crumbly, and that is ok.
  • In an 8x8 in. pan, lined with parchment, press 2/3 of the oat mixture firmly into the pan. Add the berry mixture on top to cover evenly.
  • Sprinkle over the rest of the oat mixture to cover the berries.
  • Place in the oven and bake for 25 - 30 minutes or until berries are bubbling and oats on the top are browned.
  • Allow to cool completely before cutting.
  • Enjoy!

Notes

  • If your berries are a bit tart or sour, I suggest using a touch more sugar.
  • For easier and cleaner cut bars, refrigerate these berry oat bars for several hours before cutting. This makes for much less of a mess!
  • Eat chilled or warm them up before serving. Topped with vanilla ice cream is always a win!
  • For gluten free bars, use gluten free oats and an all purpose gluten free 1:1 flour.
