Blueberry Coffee Cake (No Streusel, Crisp Sugar Crust)
This blueberry coffee cake skips the streusel and finishes with a crisp turbinado sugar crust after flipping. Made with buttermilk and fresh blueberries, it bakes soft in the center and golden on the outside—simple, reliable, and great for brunch.
In a large bowl, beat the butter and granulated sugar for about 2 minutes until light and fluffy. Add the vanilla, egg, and egg white, and mix until smooth.
¾ cup (150 g) granulated sugar, 6 tbsps. (85 g) unsalted butter, 1 tsp (5 ml) vanilla extract, 1 large egg, 1 large egg white
Add the flour mixture and buttermilk alternately to the wet ingredients, starting and ending with the flour. Mix just until combined—don’t overmix.
1⅓ cups (315 ml) buttermilk
Spoon half the batter into the prepared pan. Top with 140 g (1 cup) of blueberries. Spread the rest of the batter over and finish with the remaining 105 g (¾ cup) blueberries.
1¾ cups (245 g) fresh blueberries
Sprinkle turbinado sugar evenly over the top.
2 tbsps. (24 g) turbinado sugar
Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 20 minutes. Run a knife around the edges and flip the cake onto a plate. The turbinado sugar crust becomes the bottom—do not flip it back over. Let cool completely before serving.

Notes
Blueberries: Do not add extra blueberries to the cake batter, otherwise there will be too much moisture in the cake itself.
Turbinado Sugar: Don’t substitute with granulated sugar. It won’t create the same crust.
Buttermilk Substitute: Add 1 tbsp (15 ml) vinegar or lemon juice to a measuring cup, then fill to 315 ml with milk. Let sit for 5–10 minutes.
Storage: Store at room temperature for 2 days or freeze slices for up to 2 months.
