This post may contain affiliate links. Read my full disclosure policy. From Zingerman’s Bakehouse, a rich and buttery sour cream coffee cake with a sublime cinnamon-nut swirl. A classic breakfast cake is one of the handiest things to have in your baking repertoire, and this sour cream coffee cake from the famous Zingerman’s Bakehouse in Ann Arbor, MI is one of the very best. Featured on the cover of the Zingerman’s Bakehouse Cookbook by Amy Emberling and‎ Frank Carollo (Chronicle Books, 2017), the recipe is a treasure that’s worth the cost of the book alone. The authors write, “This is our most popular coffee cake and possibly our most popular sweet item…As you can see, it is full of tasty fat—half a pound of butter, half a pound of sour cream, and three whole eggs – which yields a mellow and moist cake crumb.” But what makes it truly special is the contrasting flavor and crunch of the cinnamon-nut swirl that runs throughout. And the cake lasts: you can store it in a covered container on the countertop for up to two weeks (but good luck keeping it that long!). “This is ‘make-over’ coffee cake for me…..I will make it over and over and over again!” What You’ll Need To Make Sour Cream Coffee Cake Walnuts: Provide a nutty crunch and texture in the cinnamon-walnut swirl, adding a rich flavor contrast to the cake’s tender crumb. Brown Sugar: Adds sweetness and caramel-like depth to the swirl, helping balance the cinnamon’s spice and making the swirl moist. Cinnamon: Delivers warm spice that’s essential to the swirl, bringing a cozy and fragrant flavor. All-Purpose Flour: Provides the structure for the cake. To ensure accuracy, measure the flour by spooning it into the measuring cup and leveling it off. Baking Soda: Acts as a leavening agent, helping the cake rise and become fluffy. Granulated Sugar: Sweetens the cake while contributing to its soft, moist texture when combined with butter. Butter: Adds richness and moisture, making the cake tender and buttery, while also helping the sugar to cream properly. Eggs: Bind the ingredients together and add structure and moisture. Sour Cream: Adds moisture and richness to the cake, while the slight tang balances the sweetness and keeps the cake soft. Vanilla Extract: Enhances the overall flavor, providing a warm, sweet aroma that complements the other ingredients.

Toast the walnuts on a rimmed baking sheet until they’re fragrant and golden brown, 10 to 15 minutes. Let cool, and reduce the oven temperature to 300°F. In a small bowl, combine the walnuts, brown sugar, and cinnamon. Mix until combined, then set aside. In another bowl, whisk together the flour, baking soda, and salt. Set aside. In the bowl of an electric mixer fitted with the paddle attachment or beaters, combine the sugar and butter. Beat on medium speed until pale and fluffy, about 3 minutes. Add the eggs, one at a time, beating well after each addition until the mixture is homogenous. On low speed, mix in the sour cream and vanilla. The batter will look a little curdled at this point; that’s okay. Scrape down the sides and bottom of the bowl to make sure all of the ingredients are evenly incorporated. Gradually add the flour mixture. And mix on low speed until the batter is smooth and homogeneous. Scoop 1/3 of the batter into the prepared pan. (It won’t seem like enough, especially if you’re using a 12-cup Bundt — that’s okay. Just do your best to smooth it into an even layer with a spatula or back of a spoon.) Sprinkle half of the cinnamon-walnut mixture evenly over the batter. Cover with another 1/3 of the remaining batter, using a spoon or spatula to spread the batter evenly over the pan and to the edges. Sprinkle the remaining nut mixture evenly over the batter. Cover with the remaining batter, spreading it evenly over the nut mixture. Bake for 65 to 75 minutes, or until a cake tester comes out clean. Cool the cake in the pan for 15 minutes. Do not let the cake cool in the pan for much longer than this or the brown sugar in the streusel might stick to the sides of the pan and make it difficult to release the cake. Place a wire rack on top of the Bundt pan and then invert the pan to release the cake. Let the cake cool completely before serving. The cake will keep well in an airtight container at room temperature for up to a week. Enjoy!

In a small bowl, mix together the walnuts, brown sugar, and cinnamon. Set aside. Reduce the oven temperature to 300°F. Spray a 9- or 10-in Bundt pan with nonstick cooking spray and dust with flour. Tap out any excess flour. Alternatively, spray the pan with a nonstick spray with flour in it, such as Baker's Joy or Pam with Flour. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside. In the bowl of an electric mixer fitted with the paddle attachment or beaters, combine the sugar and butter.
