Skillet Sour Cream Coffee Cake with Walnut Crumble


For the Cake
¾ cup unsalted butter, softened
¾ cup granulated sugar
¾ cup light brown sugar
¾ cup full fat sour cream
2 large eggs
1 tsp pure vanilla extract
1 ¾ cups unbleached all-purpose flour
1 tsp baking powder
¼ tsp baking soda
½ tsp salt
For the crumble
½ cup unbleached all-purpose flour
½ cup light brown sugar
2 tsp ground cinnamon
4 tbsp cold unsalted butter, cut into small pieces
1 cup finely chopped walnuts
1 pinch salt


For the coffee cake

Pre heat oven to 350˚ Fahrenheit. Grease a 10 inch cast iron skillet with butter or vegetable oil.

Using a stand mixer and the paddle attachment, beat the butter, granulated and brown sugar until light and fluffy. Beat in the sour cream, eggs one at a time and vanilla.

In a large bowl, whisk together the flour, baking powder, baking soda and the salt. Add the flour mixture to the butter mixture in 3 additions. Combine well but don’t over-mix.

Spread 1/2 of the batter into the prepared pan, smooth with a knife or offset spatula. Sprinkle 1/2 of the crumble onto the batter. Spread and smooth the rest of the batter over the crumble. Top with the rest of the crumble, pressing in very gently.

Bake for 40-45 minutes or until a wooden skewer comes out virtually crumb free.

For the crumble

Whisk together the flour, brown sugar and cinnamon in a bowl. Add in the butter and mix with clean hands or a pastry cutter. The crumble should stick together and the pieces of butter should be no larger than peas.
