Classic Coffee Cake

Let’s clear something up right away: coffee cake doesn’t actually have coffee in it. It’s called coffee cake because it’s meant to be enjoyed alongside a hot cup of coffee—and honestly, is there a better pairing in the world?

This classic coffee cake is everything you want it to be. A tender, buttery sour cream cake forms the base, with a ribbon of cinnamon sugar running through the middle and an absolutely generous layer of buttery streusel crumb on top.

It’s not too sweet, perfectly moist, and that crumb topping? It’s the kind you’ll find yourself picking off piece by piece. Whether it’s for breakfast, brunch, or a midday treat, this cake will make your coffee taste better.

Ingredients

Makes one 9-inch square or round cake (9-12 servings).

For the Streusel Topping & Filling:

• 1 cup (125g) all-purpose flour
• ¾ cup (150g) light brown sugar, packed
• 2 teaspoons ground cinnamon
• ¼ teaspoon salt
• ½ cup (115g) unsalted butter, melted
• 1 teaspoon vanilla extract
• ¾ cup chopped walnuts or pecans (optional)

For the Coffee Cake:

• 1 ½ cups (190g) all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon salt
• ½ cup (115g) unsalted butter, softened
• ¾ cup (150g) granulated sugar
• 2 large eggs, at room temperature
• 1 ½ teaspoons vanilla extract
• 1 cup (240g) sour cream, at room temperature

Step-by-Step Instructions

1. Preheat and Prepare:

1. Preheat your oven to 350°F (175°C). Grease a 9-inch square baking pan or 9-inch round springform pan. If using a square pan, line with parchment paper leaving overhang for easy removal.

2. Make the Streusel:

1. In a medium bowl, whisk together the flour, brown sugar, cinnamon, and salt.
2. Pour in the melted butter and vanilla extract. Stir with a fork until the mixture forms clumps and resembles wet sand. If using nuts, stir them in now.
3. Set aside. This will serve as both your filling and your topping.

3. Make the Cake Batter:

1. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
2. In a large bowl, beat the softened butter and granulated sugar together with an electric mixer until light and fluffy, about 2-3 minutes. Scrape down the sides as needed.
3. Add the eggs one at a time, beating well after each addition. Scrape down the bowl again.
4. Beat in the vanilla extract.
5. With the mixer on low speed, add half of the flour mixture, mixing until just combined. Add all of the sour cream, then the remaining flour mixture. Mix until just combined and no streaks of flour remain. Do not overmix.

4. Assemble the Cake:

1. Spread half of the cake batter evenly into the prepared pan. It will be a thick layer—use an offset spatula to spread it to the edges.
2. Sprinkle about half of the streusel mixture evenly over the batter. This will be the cinnamon swirl layer.
3. Carefully spread the remaining batter over the streusel layer. This takes a little patience—drop spoonfuls of batter over the streusel and gently spread to cover as best you can. It doesn’t have to be perfect.
4. Sprinkle the remaining streusel evenly over the top, pressing it gently so it adheres.

5. Bake:

1. Bake for 35-45 minutes, until a toothpick inserted into the center comes out clean or with a few moist crumbs.
2. If the top is browning too quickly, tent loosely with foil for the last 10-15 minutes.
3. Let the cake cool in the pan on a wire rack for at least 30 minutes before serving. It can be served warm or at room temperature.

6. Serve:

1. Slice and serve with a hot cup of coffee. The cake is delicious on its own, but a dusting of powdered sugar or a drizzle of simple glaze is always welcome.

Storage and Make-Ahead Tips

How to Store:

Store coffee cake tightly covered at room temperature for up to 4 days. The streusel will soften slightly over time, which is part of its charm. You can also store in the refrigerator, but bring to room temperature before serving.

Can You Freeze Coffee Cake?

Absolutely! Coffee cake freezes beautifully. Wrap the cooled cake (whole or in slices) tightly in plastic wrap, then in foil, and place in a freezer bag. Freeze for up to 3 months. Thaw at room temperature.

Make-Ahead for Brunch:

Coffee cake is perfect for making ahead. Bake it a day before, store at room temperature, and it’ll be ready to serve. The flavors actually meld and deepen overnight.

Freezing Unbaked:

You can assemble the entire cake in the pan, cover tightly, and freeze for up to 3 months. Bake from frozen, adding 10-15 minutes to the baking time.

Reviving Day-Old Coffee Cake:

If your coffee cake is a day or two old, warm individual slices in the microwave for 10-15 seconds. It’ll taste almost freshly baked!
