Christina Tosi’s Crockpot Cake

Step 1

Put all but 1 tablespoon of the butter and the sugars in the bowl of a stand mixer and cream with the paddle attachment at medium-high speed, until the mixture is smooth and pale, approximately 3 to 4 minutes. Mix in the eggs and vanilla, then continue to mix for another 3 minutes, until fluffy. Add the buttermilk and oil and mix briefly to combine.

Step 2

Set the mixer to a very low speed and add the cake flour, baking powder and salt, mixing for a minute or so and scraping down the sides of the bowl once or twice, until the batter has just come together, with no lumps.

Step 3

Use the remaining tablespoon of butter to grease the interior of a 4- to 6-quart slow cooker, then pour the batter into the pot. Cover and cook on low for somewhere in the neighborhood of 4 to 6 hours, until the cake has set and is cooked through at the center. To serve, run a knife around the edge of the slow cooker to loosen the cake and then carefully invert onto a platter, or simply spoon the cake out of the slow cooker.
