  • 1/2 cup granulated sugar
  • 1 egg
  • 1/4 cup sour cream
  • 1 tsp vanilla extract
  • 1/2 cup butter (1 stick), softened
  • 2.5 cups flour
  • 2/3 tsp baking soda
  • 1/2 tsp sea salt
  • 3 apples (Granny Smith, large in size)

Crumb Topping

  • 1/2 cup flour
  • 1/4 cup granulated sugar
  • 2 tbsps butter


  • Preheat oven to 350 degrees. Line a baking sheet with parchment paper.
    In a large bowl, whisk together sugar, egg, sour cream, and vanilla extract until completely combined. Add softened butter.
    In a separate bowl, whisk together flour, baking soda and salt.
    Add dry ingredients to wet and stir to combine. Knead until it just comes together, then mold into a ball. Wrap in plastic wrap and refrigerate for 30 minutes.
  • While the dough is chilling, make the crumb topping and slice your apples as instructed below.

Crumb Topping

  • Add flour, sugar to the bowl. Cut butter into small pieces and use your fingers to rub in the butter. Use just your finger-tips (not your warm hands) and quick motions, pinching your fingers to mash the small pieces of butter into the dry ingredients until moist crumbs form.
  • Slice apples thinly and set aside.
  • Remove the dough from the fridge. Halve the dough equally an shape into a ball. Roll out each ball into large flat ovals using a rolling pin. Place one of the ovals onto a parchment paper.
  • Add sliced apples on top of the first oval. Cover the apples with the second oval and pinch together to seal. Using a fork, pierce the top layer in multiple places and make a hole in the middle of the top layer.
  • Add crumb topping on top.
  • Bake for 35 to 45 minutes, or until a toothpick inserted in the center comes out clean.
    Let cool.
