Ingredients

For the jam:

  • 1 c. blueberries
  • 1 c. strawberries sliced
  • 2 c. rhubarb cut in 1/2 inch slices
  • 1/2 c. sugar
  • 1 Tablespoon lemon juice
  • 1 Tablespoon cornstarch
  • 1 teaspoon vanilla

For the cookie base:

  • 1 3/4 c. flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 c. butter softened
  • 1 c. brown sugar
  • 1 c. granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • 2 c. oats

Instructions

  • Combine all jam ingredients in a medium saucepan over medium heat.
  • Stir frequently until the fruits begin to break down, about 8-10 minutes. Remove from heat.
  • Preheat the oven to 350 degrees. Place foil in the bottom of a 13 x 9 inch pan.
  • In a medium bowl combine the flour, baking powder, salt, and cinnamon.
  • In a large mixing bowl cream together the butter, brown sugar, and granulated sugar. Mix in the eggs and vanilla.
  • Add the flour mixture to the butter mixture and mix well. Stir in the oats to combine.
  • Press 3/4 of the cookie dough into the foil lined pan. Put the remaining cookie dough in the freezer.
  • Pour the berry rhubarb jam on top of the cookie dough and spread it out evenly.
  • Crumble the remaining cookie dough over top of the jam layer. Some of the jam should be peaking through.
  • Bake for 50-60 minutes or until the crumble on top is golden brown. Remove from oven and cool completely on a wire rack.
  • Once cooled use the foil to remove the bars from the pan. Cut into 24 pieces and enjoy.
