Four Berry Pie Bars

  • Author: Lexi

  • Yield: 12-16 servings 1x
  • Diet: Vegan


We transformed grandma's tried-and-true pie recipe into these vegan, gluten-free Four Berry Pie Bars. Because everything tastes better when you eat it with your hands!




  • 3 cups old fashioned rolled oats
  • 1 cup white rice flour
  • 3/4 cup sugar
  • 1/4 cup hemp seeds
  • 2 tbsp shredded coconut
  • 2 tsp baking powder
  • 1 tsp cinnamon
  • 1/4 tsp salt
  • 1 cup vegan butter, chilled and cut into pieces
  • 3 tbsp creamy almond butter
  • 2 1/2 tbsp maple syrup
  • 1 tsp vanilla extract
  • 1/2 tsp almond extract
  • 1/2 cup raw, unsalted almonds 


  • 5 cups mixed berries (strawberries, blueberries, raspberries, cherries)
  • 1/2 cup peeled apple (grated or finely diced)
  • 3 tbsp sugar
  • 2 tbsp maple syrup
  • 2 tsp freshly squeezed lime juice
  • 1 tsp lime zest
  • 3/4 tsp cinnamon
  • 6 tbsp chia seeds



  1. Wash berries and pat dry with a clean towel to remove excess moisture. 
  2. In a small saucepan over medium heat, bring all ingredients except chia seeds to a boil. Reduce heat and simmer for 10 minutes, stirring often. Softly mash the mixture with the back of a wooden spoon to achieve a jam-like consistency. 
  3. Remove from heat and stir in chia seeds. Let sit 30 minutes to cool and thicken.


  1. Preheat oven to 350 F and line an 8x8 inch pan with parchment paper.
  2. In a food processor, pulse all dry ingredients until a crumbly mixture forms. Add wet ingredients and continue to pulse until well incorporated. You may need to transfer to a large mixing bowl and knead lightly by hand before pressing into pan.
  3. Press 1/2-2/3 of mixture into pan. Spread berry mixture over top to form an even layer.
  4. Generously sprinkle remaining crumble over the top.
  5. Bake for 33-37 minutes, until golden brown on top.
  6. Let cool in pan at room temperature for several hours - until completely cooled. Carefully remove from pan and slice into bars. 


It's important to let the bars cool completely so they have time to set. Otherwise, they're pretty messy - kind of like an actual slice of pie!
