Ingredients

  • 1 cup all purpose flour
  • ¾ cup old fashioned oats
  • cup granulated sugar
  • ¼ cup brown sugar
  • 8 tablespoon unsalted butter
  • 1 teaspoon vanilla extract
  • ¼ tsp salt
  • 10 oz blackberry preserves

Instructions

  • Preheat the oven to 350. Line an 8x8 baking dish with parchment paper.
  • In one bowl combine flour, oats and salt. In a second bowl, melt butter and whisk in granulated sugar, brown sugar and vanilla. Combine wet and dry ingredients together.
  • Press ¾ of the crumble mixture into the prepared pan. Spread the blackberry preserves on top and then press the remaining ¼ of the crumble on top.
  • Bake for 30 minutes, then let cool completely. (Once slightly cooled, refrigerate for 1 hour to speed up cooling time)
  • Cut into 16 evenly sized bars.

Notes

Substitutions:
  • Replace unsalted butter with salted and remove the ¼ teaspoon of salt. 
  • Replace blackberry preserves with any other fruit spread of choice. Or to use fresh berries, toss them with 1 tablespoon each cornstarch and sugar and layer on top the crumble. Baking time may need to increase by 5 minutes. 
  • Substitute half of the all purpose flour with wheat flour for a healthier take. 
  • Use gluten free flour and oats for a gluten free variety! 
  • Add in ¼ to ½ cup chopped nuts of your choice to the crumble (walnuts, almonds or pecans)
