This sour cream coffee cake recipe is a new and improved version of my classic coffee cake. I originally shared this recipe back in 2020, but after some reader feedback I made a few adjustments to the original recipe to make it even better.

This cinnamon streusel-topped version is incredibly simple to make and it would be perfect for brunch or Mother’s Day. It’s made in a 9-inch pan so it feeds a hungry family or small crowd comfortably, plus it’s easy to transport.

If you’ve been searching for an old-fashioned coffee cake recipe that isn’t too difficult, this is it! I guarantee everyone will be begging you for this recipe!

Here’s How We’re Making This Recipe Even Better

  • Using a different size pan. The original recipe I posted used a 9×13 pan, but I received some feedback that the batter was difficult to spread out into such a thin layer. I adjusted the recipe for a 9-inch square pan, which makes for easier spreading and yields thicker slices of coffee cake (win-win!).
  • Adding a cinnamon sugar swirl in the middle instead of streusel. My original recipe used the same streusel in the middle and the top, which was delicious but didn’t pack in enough cinnamon flavor. After multiple rounds of recipe testing, I settled on adding a swirl of cinnamon sugar to the middle which really took this cake up a notch!
  • Reduced the flour and increased the sugar slightly. This makes the cake even more moist! I found that just ¼ cup less flour in the cake batter also made it MUCH easier to spread.

The Temperature Of Your Ingredients Matters

Make sure you’re using cold butter to make the cinnamon streusel, which will help it hold its shape and become nice and crunchy as the cake bakes. If you use warm butter in the streusel, it won’t hold up as well in the oven.

However, the butter, eggs, and sour cream used in the cake batter must be at room temperature to ensure that everything mixes together thoroughly. Your butter should also be at a cool room temperature. In other words, it’s cool to the touch, but your finger leaves an indent if you press into it.

If you need to bring your ingredients for the cake batter to room temperature quickly, here’s what you can do:

  • Slice butter into small pieces and arrange them in a single layer on a plate.
  • Place the eggs in a bowl of warm tap water for 5 to 10 minutes.
  • Microwave the sour cream for 15 to 20 seconds. Make sure to keep a close eye on it though!

Tips For Making This Coffee Cake

  • Don’t over mix the streusel. I suggest using a pastry cutter to cut the cold butter into the dry ingredients. The streusel mixture is meant to feel sandy and crumbly. Once it looks like the picture above, it’s ready!
  • Cream the butter and sugar together long enough. You need to cream together the butter and sugar for a good 3 to 4 minutes. This incorporates air into the batter and will prevent your coffee cake from being too dense.
  • Measure your flour correctly. You never want to scoop your flour from the container. Instead, stir it around, spoon the flour out of the bag into your measuring cup, then level off the flour with the back of a butter knife. I have a full blog post on how to measure flour correctly, if you’re newer to baking.
  • Use a light metal pan! Dark metal pans retain more heat and often cook faster, which results in burnt edges and uneven baking. I highly recommend sticking with a light-colored pan for best results. This 9-inch USA pan is my personal favorite!

Can I Add Nuts Or Chocolate?

Absolutely! You can add up to 1 cup of chopped nuts or chocolate chips to the batter.

Can I Make This Into Muffins?

Yes, but you will need to reduce the baking time. I recommend filling each liner almost all the way to the top, then sprinkling the streusel on top. Keep in mind that you may not need all of the streusel; if that’s the case, you can freeze any extra and use it for another recipe.

This sour cream coffee cake has a ribbon of cinnamon sugar running through it and big, buttery pieces of streusel on top.

Ingredients

Servings: 16 slices

Streusel Topping

  • ¾ cup all-purpose flour spooned & leveled (95 grams)
  • ½ cup packed light brown sugar (100 grams)
  • 2 teaspoons ground cinnamon
  • Tiny pinch of salt
  • 6 tablespoons cold unsalted butter cubed into small pieces (85 grams)

Cinnamon Sugar Filling

  • cup granulated sugar (70 grams)
  • 2 teaspoons ground cinnamon

Cake

  • 1 ¾ cups all-purpose flour spooned and leveled (220 grams)
  • 1 teaspoon baking powder
  • ¼ teaspoon baking soda
  • ½ teaspoon salt
  • ½ teaspoon ground cinnamon
  • ½ cup unsalted butter softened (113 grams; 1 stick)
  • 1 ¼ cups granulated sugar (250 grams)
  • 2 large eggs at room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup sour cream at room temperature (240 grams)

Instructions
 

  • Preheat the oven to 350°F (177°C). Spray a light 9-inch square metal pan with non-stick cooking spray and set aside.
  • To make the streusel topping: Add the flour, brown sugar, cinnamon, and salt to a large mixing bowl and mix until well combined. Add the cubed butter and cut it into the dry ingredients with a pastry cutter until the mixture starts to come together and is crumbly. Cover and transfer to the refrigerator.
    ¾ cup all-purpose flour,½ cup packed light brown sugar,2 teaspoons ground cinnamon,Tiny pinch of salt,6 tablespoons cold unsalted butter
  • To make the cinnamon sugar filling: Add the granulated sugar and cinnamon to a small mixing bowl and stir until well combined. Set aside.
    ⅓ cup granulated sugar,2 teaspoons ground cinnamon
  • To make the cake: In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Set aside.
    1 ¾ cups all-purpose flour,1 teaspoon baking powder,¼ teaspoon baking soda,½ teaspoon salt,½ teaspoon ground cinnamon
  • In the bowl of a stand mixer fitted with the paddle attachment, or in a large mixing bowl using a handheld mixer, beat the butter and granulated sugar together until light and fluffy (about 3 to 4 minutes).
    ½ cup unsalted butter,1 ¼ cups granulated sugar
  • Mix in the eggs one at a time. Stop and scrape around the sides of the bowl, then mix in the vanilla extract.
    2 large eggs,2 teaspoons pure vanilla extract
  • Add half of the dry ingredients and mix on low speed until just combined. Add the sour cream and mix until just combined, then mix in the last half of the dry ingredients until just combined.
    1 cup sour cream
  • To assemble the coffee cake: Scoop half of the cake batter into the prepared pan and smooth it out into an even layer (I like to use an angled spatula for this step). Sprinkle the cinnamon sugar mixture evenly all over the top of the cake batter. Drop large spoonfuls of the remaining half of the cake batter all over the top and very gently spread it out into one even layer.
  • Remove the streusel from the refrigerator and sprinkle it evenly all over the top of the cake.
  • Bake for 40 to 50 minutes or until a toothpick inserted into the center of the cake comes out clean. If using a darker pan, the baking time will be closer to 40 minutes for a lighter pan it will take closer to 50 minutes.
  • Remove the cake from the oven and cool on a wire rack in the pan for at least 45 minutes to 1 hour, then slice and enjoy!
