Serve these Blackberry Crumble Bars for a healthy dessert everyone will love! Make them with fresh or frozen blackberries and serve them for a party or a kid-friendly evening treat.


  • 3 cups fresh (or frozen) blackberries
  • 2 Tbsp maple syrup, optional
  • 3 Tbsp chia seeds
  • 8 Tbsp butter, melted
  • 1/2 cup brown sugar
  • 1 egg
  • 1 tsp vanilla
  • 1 cup white whole wheat flour
  • 1/2 tsp baking soda
  • 2 cups rolled oats, divided
  • 1.5 cups blackberry jam


Place blackberries (and maple syrup if using) in a saucepan over medium heat.
Smash blackberries and bring mixture to a boil. 
Add chia seeds, reduce heat and simmer for 5-10 minutes. 
Transfer jam to a bowl and refrigerate at least 2 hours. 

When ready to make the bars, combine melted butter, sugar, egg and vanilla in a large bowl and mix well.
Add flour, baking soda and 1.5 cups oats and stir to combine. 
Press 2/3 of the mixture into a 9x9 pan (greased or lined with parchment paper). 
Add remaining 1/2 cup oats to remaining 1/3 of the mixture and mix well. 
Spread 1.5 cups of the chia jam you made earlier over the mixture in the pan. 
Crumble the remaining oat mixture over the top. 
Bake at 350 degrees for 30 minutes. 
Let cool before cutting. 


Recipe Notes

I store these in the fridge!
If your blackberries are on the sweeter side, you don't need to add the maple syrup. I only added it because mine were pretty tart.
