Sour Cream Coffee Cake with Brown Sugar-Pecan Streusel

I can still picture my grandmother’s kitchen, bathed in the warm glow of the morning sun. The air, thick with the aroma of cinnamon and toasted nuts, always meant one thing: her legendary coffee cake. It wasn’t just a cake; it was a hug in every bite. The tender crumb, the tangy sour cream, the sweet and nutty streusel – it was a symphony of flavors and textures that transported me back to childhood, a time when worries were few and life was sweet. This recipe, adapted from America’s Test Kitchen, captures that same magic, bringing a slice of nostalgia to every occasion.

• Prep Time: 30 minutes
• Cook Time: 60 minutes
• Total Time: 1 hour 30 minutes
• Servings: 12-16
• Yield: 1 cake
• Dietary Type: Not Gluten-Free

Ingredients

For the Streusel:

• ¾ cup unbleached all-purpose flour (3 ¾ ounces)
• ¾ cup granulated sugar (5 ¼ ounces)
• ½ cup dark brown sugar, packed (3 ½ ounces), divided
• 2 tablespoons ground cinnamon
• 2 tablespoons cold unsalted butter
• 1 cup pecans, chopped

For the Cake:

• 4 large eggs
• 1 ½ cups sour cream, divided
• 1 tablespoon vanilla extract
• 2 ¼ cups unbleached all-purpose flour (11 ½ ounces)
• 1 ¼ cups granulated sugar (8 ¾ ounces)
• 1 tablespoon baking powder
• ¾ teaspoon baking soda
• ¾ teaspoon salt
• 12 tablespoons unsalted butter, softened but still cool, cut into 1-inch cubes (1 ½ sticks)

Equipment Needed

• Fixed-bottom, 10-inch tube pan (with 10-cup capacity)
• Food processor (optional, pastry cutter can be substituted)
• Small bowl
• Standing mixer
• Rubber spatula
• Offset metal spatula (or additional rubber spatula)
• Toothpick
• Cooling rack

Instructions

1. Preheat and Prepare: Adjust the oven rack to the lowest position and preheat the oven to 350 degrees Fahrenheit. Thoroughly grease the inside of a 10-inch tube pan.

2. Make the Streusel – First Part: Place the ¾ cup flour, ¾ cup granulated sugar, ¼ cup dark brown sugar, and 2 tablespoons cinnamon in a food processor. Pulse a few times to combine the ingredients.

3. Divide the Streusel: Transfer 1 ¼ cups of the streusel mixture to a small bowl. Stir in the remaining ¼ cup brown sugar; set aside. This will be the streusel for the inside of the cake.

4. Make the Streusel – Second Part: Add the 2 tablespoons cold butter and 1 cup chopped pecans to the remaining dry ingredients in the food processor bowl. Pulse the mixture about 3-4 times until the nuts and butter have been broken down into small pebbly pieces. Set aside. This streusel, with the butter and nuts, will be for the top of the cake.
   Note: If you do not have a food processor, you can use a pastry cutter, but it will take more time.

5. Prepare the Wet Ingredients: In a small bowl, combine the 4 eggs, 1 cup of the sour cream, and 1 tablespoon vanilla extract. Set aside.

6. Combine Dry Ingredients: In the bowl of a standing mixer, combine the 2 ¼ cups flour, 1 ¼ cups granulated sugar, 1 tablespoon baking powder, ¾ teaspoon baking soda, and ¾ teaspoon salt at low speed, about 30 seconds.

7. Incorporate Butter and Sour Cream: Add the 12 tablespoons butter and the remaining ½ cup sour cream to the dry ingredients. Mix at low speed until the dry ingredients are moistened. Increase the speed to medium and beat for 30 seconds.

8. Add Egg Mixture: Scrape down the sides of the bowl with a rubber spatula. Decrease the mixer speed to low and slowly incorporate the egg mixture in 3 additions, beating for 20 seconds after each and scraping the sides of the bowl as necessary.

9. Aerate the Batter: Increase the speed to medium-high and beat for 1 minute. The batter should increase in volume and become aerated and pale in color.

10. Layer the Cake: Add 2 cups of the batter to the prepared tube pan. With an offset metal spatula or rubber spatula, smooth the surface of the batter.

11. Add First Streusel Layer: Sprinkle with ¾ cup of the streusel filling (without butter or nuts).

12. Add Second Batter Layer: Drop 2 more cups of the batter over the streusel and spread evenly.

13. Add Second Streusel Layer: Add the remaining streusel filling (without butter or nuts).

14. Top with Remaining Batter: Top with the remaining batter and spread evenly.

15. Add Streusel Topping: Sprinkle the streusel topping (with the butter and nuts) evenly over the top of the cake.

16. Bake: Bake until the cake feels firm to the touch and a toothpick inserted into the center comes out clean, about 60 minutes. Note: Baking times can vary depending on the oven. Start checking for doneness around 50 minutes.

17. Cool: Cool the cake in the pan for 30 minutes.

18. Release and Cool Completely: Then, release the clasps of the springform pan and cool completely on a wire rack before serving.

Expert Tips & Tricks

• Soft Butter is Key: While the recipe calls for softened butter, make sure it’s still relatively cool. Butter that’s too soft will result in a greasy cake.
• Don’t Overmix: Overmixing the batter develops the gluten in the flour, which leads to a tough cake. Mix until just combined.
• Test for Doneness: If the top is browning too quickly, tent the cake with aluminum foil during the last 15-20 minutes of baking. Always test for doneness with a toothpick.
• Even Streusel Distribution: For even streusel coverage, sprinkle it from a height and avoid dumping it in clumps.
• Make Ahead: The streusel can be made a day or two in advance and stored in an airtight container at room temperature.
• Room Temperature Ingredients: Using room temperature eggs allows them to emulsify more easily into the batter, resulting in a smoother, more even texture.

FAQs (Frequently Asked Questions)

Q: Why is a tube pan recommended for this recipe?
A: The tube pan allows for even heat distribution, ensuring that the cake bakes evenly and rises properly. The center tube helps the cake cook from the inside out.

Q: Can I use a springform pan instead of a tube pan?
A: Yes, you can use a 10-inch springform pan, but keep in mind that the baking time may need to be adjusted slightly.

Q: What if I don’t have a food processor?
A: You can use a pastry cutter to cut the butter into the dry ingredients for the streusel. It will take a bit more time and effort.

Q: How do I prevent the streusel from sinking to the bottom of the cake?
A: Layering the streusel between layers of batter helps to keep it evenly distributed throughout the cake.

Q: Can I freeze the coffee cake?
A: Yes, you can freeze the coffee cake for up to 2 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn.
