  • Blondie Layer
  • 1 stick butter
  • 1 cup light brown sugar
  • 1 egg
  • 1/2 teaspoon vanilla
  • 1 teaspoon salt
  • 1 cup flour
  • Apple Layer
  • 2 large apples peeled and cut in 1/4" slices
  • 1/3 cup light brown sugar
  • 1 teaspoon cinnamon
  • 1/2 teaspoon nutmeg
  • 1 teaspoon salt
  • 1 tablespoon cornstarch
  • Crumble Layer
  • 1/2 stick butter cut into 1/4" cubes
  • 1/2 cup light brown sugar
  • 1 cup rolled oats
  • 2/3 cup flour
  • 1 teaspoon salt
  • *You can always add caramel nuts, or other fun things to the crumble too! Or as a fun sauce!


  • Preheat oven to 350 degrees
  • Grease 9x9" pan and set aside
  • Melt the butter on low/medium heat and blend with the sugar in your stand mixer, or using a large bowl. Pour into the bottom of your greased pan and bake in the oven for 15 minutes.
  • While the blondie is baking, using the same bowl your batter was just in, add the apple slices, and the rest of the dry ingredients in the bowl, folding in everything (and even scrap down the blondie batter). Once the blondie base is baked, immediately spread the apples on top of the blondie.
  • For the crumble topping, in a medium sized bowl, sift in the dry ingredients. Add the butter cubes and begin to mix everything together until it's the right crumble consistency, (or using a food processor to do the same step). Put the crumble topping on top of the apples and pat it down so it flattens as much as possible. Bake the crumble for another 15 minutes and let cool for another 20 minutes before serving.
