This recipe delivers what every coffee cake should: a pillowy soft crumb, balanced sweetness, and generous layers of that irresistible cinnamon streusel both nestled inside and crowning the top. The secret lies in the careful layering technique and using sour cream for that tender, bakery-quality texture that keeps people coming back for seconds (and thirds).

Ingredients
For the Cinnamon Streusel
- 1¼ cups (157g) all-purpose flour
- ¾ cup + 2 tbsp (130g) light brown sugar (packed)
- 2 tsp ground cinnamon (adjust to taste preference)
- ¼ tsp salt
- A pinch of baking powder
- ½ cup (113g) unsalted butter (room temperature)
For the Coffee Cake
- ¾ cup (170g) unsalted butter (room temperature)
- 1½ cups (315g) granulated white sugar
- 1¼ cups (300g) sour cream or Greek yogurt (room temperature)
- 1½ tbsp pure vanilla extract
- 3 large eggs (room temperature)
- 2½ cups (315g) cake flour (sifted)
- 2 tsp baking powder
- ½ tsp baking soda
- ¾ tsp salt
Detailed Instructions
Preparing the Streusel
- Combine dry streusel ingredients in a medium bowl: whisk together the all-purpose flour, brown sugar, cinnamon, salt, and baking powder until evenly distributed. The mixture should have a consistent color with no lumps of brown sugar.
- Create the streusel crumble by adding the room temperature butter to the dry mixture. Using clean fingers, pinch and rub the ingredients together until they form coarse crumbs that hold together when squeezed. The texture should resemble wet sand with some larger clumps - this creates the perfect streusel texture after baking.
Making the Cake Batter
- Cream butter and sugar in the bowl of a stand mixer (or large bowl if using hand mixer). Beat on medium-low speed initially, gradually increasing to high over 6-8 minutes. Scrape down bowl sides every 2 minutes. The mixture should become pale, fluffy, and significantly increased in volume - this aeration is crucial for a light cake texture.
- Add wet ingredients by reducing mixer speed to medium-low and incorporating the sour cream and vanilla extract. Mix until just combined, about 1 minute. The mixture may look slightly curdled at this stage, which is normal.
- Incorporate eggs individually on medium-low speed, adding one egg at a time and mixing until just incorporated before adding the next. Don't overmix - you want to maintain the airiness created during the creaming process.
- Prepare dry ingredients by whisking together cake flour, baking powder, baking soda, and salt in a separate bowl. This ensures even distribution and prevents pockets of leavening agents.
- Combine wet and dry ingredients with mixer on lowest speed, adding the flour mixture in three equal additions. Mix until just barely combined after each addition. Finish by hand using a rubber spatula and the cut-and-fold method to ensure no flour pockets remain while preserving the batter's light texture.
Assembly and Baking
- Prepare your pan by preheating oven to 350°F (180°C) and lining a 9x9-inch cake pan with parchment paper, leaving 2-inch overhangs on all sides for easy removal.
- Layer the cake by spooning half the batter into the prepared pan, spreading evenly with an offset spatula. Sprinkle ¾ of the streusel mixture evenly over this layer, then carefully spoon the remaining batter on top, spreading gently to avoid disturbing the streusel layer. Finish by sprinkling the remaining streusel over the top.
- Bake for 50-60 minutes until the top is golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs. The internal temperature should reach 205°F (96°C).
- Cool completely on a wire rack for at least 2 hours before removing from pan using parchment overhangs. This prevents the cake from falling apart and allows the flavors to meld perfectly.
Chef's Tips for Success
- Temperature matters: Ensure all ingredients are truly at room temperature (about 68-70°F) for optimal mixing and texture. Cold ingredients can cause the batter to curdle or mix unevenly.
- Don't overmix the batter: Once flour is added, mix only until just combined. Overmixing develops gluten, resulting in a tough, dense cake instead of the tender crumb you're after.
- Streusel consistency is key: The butter should be soft enough to blend easily but not melted. If it's too hard, the streusel won't form proper clumps; too soft and it'll disappear into the cake.
- Layer with confidence: When adding the second layer of batter, dollop it gently across the surface rather than pouring in one spot to avoid disturbing the middle streusel layer.
- Storage extends flavor: This cake actually improves after the first day as the flavors meld and the texture becomes even more tender. Store covered at room temperature for up to 4 days.
Nutritional Benefits
Compared to many commercial coffee cakes loaded with artificial additives and excessive sugar, this homemade version offers several advantages. Sour cream provides probiotics for digestive health and creates moisture without excessive butter. Real vanilla extract delivers antioxidants and authentic flavor without artificial compounds. Cinnamon contains anti-inflammatory compounds that may help regulate blood sugar levels. Eggs contribute high-quality protein for sustained energy, while cake flour creates a lighter texture that feels less heavy than dense, overly rich alternatives. The controlled sugar content allows you to enjoy a sweet treat without the sugar crash of overly processed options.
Storage and Serving
Store this coffee cake covered at room temperature for up to 4 days, or refrigerate for up to one week. The cake actually improves in flavor and moisture after the first day as the ingredients meld together. Serve at room temperature for the best texture and flavor experience. This cake is perfect for make-ahead entertaining - bake it the day before your event for optimal taste and convenience. Individual squares can be wrapped and frozen for up to 3 months; thaw at room temperature for 2 hours before serving.

FAQ Section
A: Absolutely! Greek yogurt works perfectly as a 1:1 substitute for sour cream. Choose full-fat Greek yogurt for the best texture and richness. The cake will have a slightly tangier flavor, which many people prefer.
A: This usually happens when the batter is too thin or the streusel butter is too soft. Make sure your batter has the proper consistency (should hold soft peaks when lifted with a spoon) and that your streusel butter is room temperature but not warm or melted.
A: Yes! This cake actually improves after a day as flavors meld. Bake completely, cool, and store covered at room temperature for up to 4 days. You can also wrap individual pieces and freeze for up to 3 months.
A: Create a substitute by measuring 2½ cups all-purpose flour, removing 5 tablespoons, then adding 5 tablespoons cornstarch. Sift this mixture three times for the best texture approximation.
A: The top should be golden brown and spring back lightly when touched. A toothpick inserted in the center should come out clean or with just a few moist crumbs. Internal temperature should reach 205°F (96°C).
A: Yes! Fold in ½ cup of chopped walnuts, pecans, or fresh blueberries with the last addition of flour. For dried fruit, toss with a tablespoon of flour first to prevent sinking.
A: Dense cake usually results from overmixing after adding flour, using ingredients that are too cold, or not creaming the butter and sugar long enough initially. Follow timing guidelines carefully for best results.
A: A 9x9-inch square pan works perfectly and gives ideal thickness. You can use a 9x13-inch pan for a thinner cake (reduce baking time to 35-45 minutes) or two 8-inch round pans for layer cake presentation.
Glossary of Key Terms
Cake Flour: A finely milled flour with lower protein content than all-purpose flour, creating more tender baked goods with a delicate crumb structure.
Creaming Method: The technique of beating butter and sugar together at high speed to incorporate air, creating light, fluffy texture in the final baked good.
Cut-and-Fold Method: A gentle mixing technique using a rubber spatula to combine ingredients by cutting down through the mixture and folding over, minimizing gluten development.
Crumb: The internal texture of baked goods; a good coffee cake should have fine, even crumb that's tender and moist rather than coarse or dry.
Offset Spatula: A flat, angled spreading tool that makes it easy to evenly distribute batter or frosting without disturbing layers underneath.
Overhangs: Parchment paper extensions beyond the pan edges that create handles for easy removal of baked goods without breaking.
Room Temperature: Ingredients at approximately 68-70°F that mix more easily and create better texture; typically achieved by leaving items out for 1-2 hours before baking.
