Ingredients You’ll Need

Before we get started, let’s gather all the ingredients. Most of these are pantry staples, so you might already have them on hand!

For the Cake:

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1 cup sour cream
  • 2 large eggs
  • 1 tsp vanilla extract

For the Oatmeal Streusel Topping:

  • 1/2 cup rolled oats
  • 1/4 cup all-purpose flour
  • 1/4 cup brown sugar
  • 1/4 cup unsalted butter, cold and cubed
  • 1 tsp ground cinnamon

Step-by-Step Instructions

1. Preheat and Prep

Start by preheating your oven to 350°F (175°C). Grease a 9-inch round cake pan or line it with parchment paper for easy removal. This step ensures your cake won’t stick and will come out perfectly every time.

2. Make the Streusel Topping

In a small bowl, combine the rolled oats, flour, brown sugar, and cinnamon. Add the cold, cubed butter and use your fingers to mix until the mixture resembles coarse crumbs. The key here is to keep the butter cold—this ensures the streusel stays crumbly and doesn’t melt into the cake during baking. Set the streusel aside while you prepare the batter.

3. Prepare the Cake Batter

In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. Add the softened butter, sour cream, eggs, and vanilla extract. Mix until just combined—be careful not to overmix! Overmixing can lead to a dense cake, so stop as soon as the ingredients are incorporated.

4. Assemble and Bake

Pour the batter into the prepared pan and spread it evenly with a spatula. Sprinkle the oatmeal streusel topping over the batter, covering it completely. The streusel will form a delicious, crunchy layer as it bakes.

Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and spring back lightly when touched.

5. Cool and Serve

Let the cake cool in the pan for 10 minutes before transferring it to a wire rack. This allows the cake to set and makes it easier to slice. Serve warm with a cup of coffee or tea for the ultimate cozy experience.


Tips for the Perfect Coffee Cake with oatmeal streusel

  • Use Cold Butter for Streusel: This ensures the topping stays crumbly and doesn’t melt into the cake.
  • Don’t Overmix the Batter: Overmixing can make the cake dense. Mix until just combined.
  • Add a Glaze: For extra sweetness, drizzle a simple glaze made of powdered sugar and milk over the cooled cake.
  • Experiment with Add-Ins: Fold in fresh blueberries, diced apples, or chopped nuts for a personalized twist.

Why This Recipe Works

The combination of sour cream and butter keeps the cake moist and tender, while the oatmeal streusel adds a satisfying crunch. It’s a balanced treat that’s not overly sweet, making it perfect for any time of day. Plus, the recipe is flexible, so you can easily adapt it to suit your preferences.

To make this recipe even easier, here are some kitchen tools I recommend:
