Ingredients

  • 10 Tbs unsalted butter, room temperature
  • 2 ½ cups all-purpose flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 cup granulated sugar
  • 3 large eggs
  • 1 ¼ cups sour cream
  • 1 tsp vanilla
  • Crumb topping (recipe below)
  • Confectioners' sugar, for dusting

Crumb Topping

  • 3 cups all-purpose flour
  • 1 cup packed light brown sugar
  • 1 Tbsp ground cinnamon
  • 1 ½ tsp salt
  • 1 ¾ cups cups (3 ½ sticks) unsalted butter, room temperature

Instructions

  • Pre-heat oven to 350 degrees and lightly butter a 9″x13″ pan.
  • In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  • In the bowl of an electric mixer or in a large bowl with a hand mixer, beat butter and sugar on medium speed until light and fluffy, 2-3 minutes.
  • Add eggs, one at a time, mixing well after adding each. Add vanilla, flour mixture, and sour cream, mixing until just blended, taking care not to over-mix.
  • Spread batter evenly into prepared pan. Spread the crumb topping over the batter in the pan.
  • Bake for 45 to 50 minutes until golden brown, turning the pan once during baking. Cool on a wire rack.

Crumb Topping

  • In a large bowl, mix together flour, brown sugar, cinnamon, and salt.
  • Using a pastry blender, a fork, or your fingers, cut in the butter. When well-mixed, the mixture should form large, moist clumps.
