Half cake, half crumb topping, this yeasted sour cream coffee cake is everything a coffee cake should be.
Ingredients
  • CAKE:
  • ½ cup melted butter
  • ½ cup granulated sugar
  • ¼ cup milk
  • 1½ cups sour cream
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 tsp instant yeast (not regular active dry yeast)
  • 2⅔ cups all purpose flour
  • 1 tsp salt
  • CRUMB LAYER:
  • 1 cup melted butter
  • ⅔ cup granulated sugar
  • 1 cup brown sugar
  • 1 tsp ground cinnamon
  • ½ tsp salt
  • 3 cups all purpose flour
  • 2 tsp baking powder
  • GARNISH:
  • ⅛ cup icing sugar (powdered sugar)
Instructions
  1. Combine all cake ingredients in a large mixing bowl and stir until fully combined, then stir for another two minutes. Cover with plastic wrap and let rise in a draft-free place for 1 hour, until slightly puffy.
  2. Meanwhile, make the crumb layer: Mix the melted butter, both sugars, cinnamon, and salt in a large bowl. Add two cups of flour and the baking powder and stir until combined, then add the last cup of flour and stir until it is fully incorporated - it will be thick and stiff! Press the mixture down into the bottom of the bowl and set aside until needed.
  3. After the cake batter has risen, lightly grease a 9x13" pan and line the bottom with parchment paper. Use your hands to sprinkle the crumb mixture evenly over the bottom of the pan. Press it down lightly and then pour the batter evenly over top. Gently smooth it out with a spatula, cover again with plastic wrap (not letting it touch the batter) and let rise another 30 minutes.
  4. Toward the end of the 30 minutes, preheat your oven to 350 degrees. Bake the cake in the preheated oven for 42-45 minutes, until a tester comes out clean. Let cool in the pan for 5 minutes, then run a knife around the edge and invert onto a cooling rack or serving platter. Dust thoroughly with the icing sugar.
Notes
