Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened to room temperature
- 1 cup granulated sugar
- 2 large eggs, at room temperature
- 1 cup full-fat sour cream, at room temperature
- 1 teaspoon pure vanilla extract
- 1/2 cup light brown sugar, packed
- 2 teaspoons ground cinnamon
- 1/2 cup chopped walnuts or pecans (optional)
Equipment Needed
- 9-inch square or round baking pan
- Parchment paper
- Mixing bowls (2 medium, 1 small)
- Electric mixer or whisk
- Spatula
- Measuring cups and spoons
- Wire cooling rack
Instructions
Step 1: Prepare the Pan and Preheat Oven
Preheat your oven to 350°F. Line a 9-inch square or round baking pan with parchment paper, leaving an overhang on two opposite sides for easy removal. Lightly grease any exposed pan surfaces. This preparation ensures your cake releases cleanly without sticking. While the oven heats, measure all your ingredients. Having everything ready before mixing creates a smoother baking process. Room temperature ingredients incorporate more evenly, so take your butter, eggs, and sour cream out about 30 minutes before starting. Tip: For easy parchment placement, cut a square slightly larger than your pan, then make diagonal cuts from each corner toward the center to create flaps that fit neatly.
Step 2: Mix Dry Ingredients and Make Cinnamon Swirl
Step 3: Cream Butter and Sugar, Then Add Wet Ingredients
In a separate medium bowl, use an electric mixer on medium speed to beat 1/2 cup softened unsalted butter with 1 cup granulated sugar until light and fluffy, about 2-3 minutes. The mixture should pale in color and increase slightly in volume. Add 2 large eggs one at a time, beating well after each addition until fully incorporated. Then mix in 1 teaspoon pure vanilla extract. Scrape down the bowl sides with a spatula to ensure even mixing. Tip: If your butter isn’t properly softened, cut it into tablespoon-sized pieces and let sit for 10-15 minutes. Do not microwave, as melted butter changes the texture.
Step 4: Combine Wet and Dry Mixtures Alternately with Sour Cream
With mixer on low speed, add one-third of the flour mixture to the butter mixture, mixing just until combined. Follow with half of the 1 cup sour cream, mixing until incorporated. Repeat with another third of flour, the remaining sour cream, and finally the last third of flour. Mix only until no dry streaks remain; overmixing develops gluten and makes cake tough. The batter will be thick but spreadable. This alternating method helps maintain the cake’s tender texture by preventing overworking the flour. Room temperature sour cream blends more smoothly than cold.
Step 5: Layer Batter and Cinnamon Swirl, Then Bake
Spread half the batter evenly in your prepared pan. Sprinkle all the cinnamon-sugar mixture (with nuts if using) evenly over the batter. Carefully spread the remaining batter over the cinnamon layer, using a spatula to cover completely. Bake at 350°F for 40-45 minutes. The cake is done when a toothpick inserted into the center comes out clean or with a few moist crumbs, and the top springs back when lightly pressed. The edges will pull slightly from the pan sides. Tip: Rotate the pan halfway through baking for even browning if your oven has hot spots.
Step 6: Cool and Serve
Place the pan on a wire cooling rack and let cool for 20 minutes. Using the parchment overhang, lift the cake from the pan and transfer directly to the rack. Cool completely before slicing, about 1-2 hours. This cooling period allows the structure to set, making cleaner slices. Serve at room temperature. The cake keeps well covered at room temperature for 3 days or frozen for up to 3 months. For clean slices, use a sharp knife and wipe between cuts. No glaze is needed, but a simple powdered sugar dusting adds visual appeal.
Tips and Tricks
For optimal texture, use full-fat sour cream rather than light versions. The higher fat content contributes to moisture and tenderness. If you only have Greek yogurt, use an equal amount but expect a slightly tangier flavor. To test baking powder freshness, mix 1 teaspoon with 1/3 cup hot water—it should bubble immediately. For even easier removal, grease the parchment paper lightly after placing it in the pan. If your cake browns too quickly, tent loosely with aluminum foil after 30 minutes of baking. For high-altitude baking (above 3,000 feet), reduce baking powder to 3/4 teaspoon and sugar to 7/8 cup, and add 2 tablespoons extra flour. Measure flour correctly by spooning into cups and leveling—scooping packs too much flour. Room temperature ingredients blend more smoothly; if short on time, place eggs in warm water for 5 minutes and cut butter into small pieces.
Recipe Variations
- Fruit Addition: Fold 1 cup fresh or frozen blueberries into the batter with the final flour addition. If using frozen, do not thaw to prevent color bleeding.
- Nut-Free Option: Replace walnuts with an equal amount of rolled oats or omit entirely. The cinnamon swirl provides sufficient texture contrast.
- Different Pan: Use a 9×13-inch pan for a thinner cake, reducing bake time to 30-35 minutes. Or try a Bundt pan, greasing thoroughly and baking 45-50 minutes.
- Flavor Twist: Add 1 teaspoon orange zest to the batter and replace vanilla with almond extract for a citrus-almond version.
- Topping Variation: Before baking, sprinkle the top with a streusel made from 1/4 cup each flour, brown sugar, and cold butter pieces rubbed together.
Frequently Asked Questions
Can I make this coffee cake ahead of time?
Yes, bake the cake completely, cool it, and wrap tightly in plastic wrap. Store at room temperature for up to 2 days or freeze for 3 months. The flavor often improves after resting overnight as the cinnamon distributes more evenly.
What if I don’t have sour cream?
Plain full-fat Greek yogurt works as a direct substitute. For a dairy-free version, use an equal amount of coconut cream mixed with 1 teaspoon lemon juice. The texture may vary slightly with substitutions.
How do I know when the cake is fully baked?
Insert a toothpick into the center—it should come out clean or with a few moist crumbs, not wet batter. The cake top should spring back when lightly pressed, and edges will pull slightly from the pan.
Can I double this recipe?
Yes, double all ingredients and use a 9×13-inch pan. Increase baking time to 45-55 minutes, checking for doneness from 45 minutes onward. Ensure your mixer bowl is large enough to handle the increased volume.
Why did my cake sink in the middle?
This usually indicates underbaking or opening the oven door too early. Bake until the center tests done, and avoid opening the oven during the first 30 minutes. Also check that your baking powder and soda are fresh.
Summary
This sour cream coffee cake delivers moist texture with minimal effort. The cinnamon swirl adds flavor interest, while simple ingredients ensure accessibility. Perfect for breakfast or dessert.
