🫐 Sour Cream Blueberry Coffee Cake
🕒 Total Time: ~1 hour
🍽️ Yields: 1 9-inch cake or 9×13 pan
🧾 Ingredients:
For the Cake:
-
1/2 cup (1 stick) unsalted butter, softened
-
1 cup granulated sugar
-
2 large eggs
-
1 teaspoon vanilla extract
-
1 cup full-fat sour cream
-
2 cups all-purpose flour
-
1 teaspoon baking powder
-
1/2 teaspoon baking soda
-
1/4 teaspoon salt
-
1 1/2 cups fresh or frozen blueberries (toss in 1 tsp flour if using frozen)
For the Streusel Topping:
-
1/2 cup brown sugar
-
1/2 cup all-purpose flour
-
1 teaspoon cinnamon
-
1/4 cup cold butter, cubed
👩🍳 Instructions:
1. Preheat Oven & Prep Pan:
-
Preheat oven to 350°F (175°C).
-
Grease a 9-inch round pan, 9×9 square, or 9×13 for a thinner cake.
2. Make Streusel:
-
In a small bowl, mix brown sugar, flour, and cinnamon.
-
Cut in cold butter with a fork or fingers until crumbly. Set aside.
3. Mix Cake Batter:
-
In a large bowl, cream together butter and sugar until light and fluffy (2–3 mins).
-
Beat in eggs one at a time, then add vanilla.
-
Mix in sour cream until smooth.
4. Combine Dry Ingredients:
-
In a separate bowl, whisk flour, baking powder, baking soda, and salt.
-
Gradually add dry ingredients to the wet, mixing just until combined.
5. Add Blueberries:
-
Gently fold in the blueberries. Don’t overmix.
6. Assemble Cake:
-
Pour batter into prepared pan and spread evenly.
-
Sprinkle streusel evenly over the top.
7. Bake:
-
Bake for 40–50 minutes (round pan) or 30–40 minutes (9×13)
-
Check doneness with a toothpick — it should come out clean or with a few moist crumbs.
8. Cool & Serve:
-
Let cool for 15–20 minutes before slicing.
-
Optional: dust with powdered sugar or drizzle with a vanilla glaze.
🍽️ Tips & Variations:
-
Add a lemon zest to the batter for a lemon-blueberry twist.
-
Use a bundt pan for a fancier presentation (adjust bake time to 50–60 minutes).
-
Swap sour cream for plain Greek yogurt if needed.
