Preheat oven to 350. Layer parchment into a 8x8 pan.

Mix crust and topping ingredients in a medium sized bowl. Add butter and stir until crust holds together when pinched.

Add 3/4 of the mixture into the pan. Firmly press the crust down using a rubber spatula or flat bottomed ramekin.

Add fruit into a medium sized pot over medium heat. Once fruit starts to soften add lemon juice, maple syrup and vanilla. Continue to cook until fruit has completely broken down. Reduce heat to low and add cornstarch. Cook for 2 more minutes. Remove from the heat and add chia seeds. Stir well and allow mixture to cool slightly.

Spread fruit mixture over crust in an even layer.

Scatter remaining crust over the top of the fruit and place in the oven.

Bake for 40-45 minutes or until the crust starts to turn brown.

Wait for the bars to cool completely before slicing.

Serve with ice cream, yogurt or whipped cream.
