What Makes a Coffee Cake Special
Despite the name, coffee cake does not usually contain coffee. Instead, it is designed to be enjoyed alongside a cup of coffee or tea. Coffee cakes are known for their tender crumb, layered or swirled fillings, and often a streusel or nut topping.
This sour cream blueberry version follows that tradition while adding fruit for freshness and color. The Bundt pan presentation elevates the cake visually, making it look impressive with very little extra effort. Once sliced, the layers of blueberries and cinnamon sugar reveal themselves, making each piece both beautiful and flavorful.
Ingredient Breakdown and Their Roles
Understanding the purpose of each ingredient helps ensure success and allows you to adapt the recipe confidently.
Granulated Sugar
Granulated sugar sweetens the cake and helps create a tender crumb by incorporating air when beaten with butter. The relatively generous amount balances the tang of the sour cream and the natural acidity of the blueberries.
Unsalted Butter
Butter provides richness, flavor, and structure. Using unsalted butter allows you to control the overall salt level of the cake. Beating the butter with sugar until light and fluffy is crucial for a soft, well-risen cake.
Eggs
Eggs bind the ingredients together and add moisture. They also contribute to the cake’s structure and stability, especially important in a Bundt pan where even baking matters.
Sour Cream
Sour cream is one of the key ingredients in this recipe. Its fat content and acidity result in a moist, tender crumb. It also enhances flavor, giving the cake a subtle tang that complements the sweetness of the fruit and sugar.
Vanilla Extract
Vanilla adds warmth and depth, enhancing all the other flavors without overpowering them. Pure vanilla extract is recommended for the best aroma.
All-Purpose Flour
Flour provides structure. The quantity used here ensures the cake is sturdy enough to hold blueberries and a sugar swirl while remaining soft and moist.
Baking Powder
Baking powder is the leavening agent that helps the cake rise. It creates a light texture without making the crumb airy or dry.
Salt
A small amount of salt balances sweetness and enhances flavor. It is essential even in sweet baking.
Blueberries
Blueberries add bursts of juiciness and natural sweetness. Fresh blueberries offer the best texture, but frozen ones work well too if used properly. They bring color, moisture, and a fresh fruit flavor that defines this cake.
Light Brown Sugar
Brown sugar is used in the swirl layer. Its molasses content adds depth and a caramel-like flavor that pairs beautifully with cinnamon and pecans.
Pecans
Pecans add crunch and a nutty richness. Finely chopped pecans distribute evenly through the swirl, ensuring texture in every bite without overpowering the cake.
Cinnamon
Cinnamon provides warmth and aroma. It transforms the brown sugar and nuts into a classic coffee cake filling that feels cozy and familiar.
Powdered Sugar
Powdered sugar is used as a final decorative touch. It adds visual appeal without making the cake overly sweet.
Step-by-Step Baking Process Explained
Preparing the Pan
A Bundt pan must be well-greased and floured to prevent sticking. Because of the cake’s moist texture and sugar swirl, this step is especially important. Take time to coat every crevice.
Creaming Butter and Sugar
Beating butter and granulated sugar until light and fluffy incorporates air into the batter. This step sets the foundation for a soft crumb and proper rise.
Adding Eggs and Dairy
Eggs are added one at a time to ensure proper emulsification. Sour cream and vanilla are then mixed in, creating a smooth, rich batter.
Incorporating Dry Ingredients
The flour, baking powder, and salt are mixed separately and added gradually. This prevents overmixing, which can lead to a dense cake. The batter should be smooth but not overworked.
Folding in Blueberries
Blueberries are gently folded in to avoid breaking them and turning the batter purple. This keeps the fruit intact and evenly distributed.
Creating the Swirl
Layering half the batter, then the cinnamon–pecan mixture, followed by the remaining batter creates a beautiful swirl. Gently swirling with a knife ensures the layers blend slightly without losing definition.
Baking
The cake is baked at 175°C (350°F) for about one hour. Baking time may vary depending on your oven, so checking for doneness with a toothpick is important. The cake is done when the toothpick comes out clean or with a few moist crumbs.
Cooling and Serving
Allow the cake to cool briefly before inverting. Cooling helps the structure set and prevents breakage. A final dusting of powdered sugar adds a simple, elegant finish.
