How To Make This Blueberry Coffee Cake
I start by making the streusel. Roughly chopped pecans are tossed with light brown sugar, ground cinnamon, ground nutmeg, all-purpose flour, unsalted butter, and vanilla bean paste. The streusel is chilled until ready to use.
The oven is preheated to 350 degrees F., and an 8 x 8-inch baking pan is buttered and lined with parchment paper on the bottom and two opposite sides.
All-purpose flour, baking soda, baking powder, and kosher salt are added to a small mixing bowl, whisked to combine and set aside momentarily. Whole milk, sour cream, fresh lemon juice, fresh lemon zest, and vanilla bean paste are added to a small mixing bowl, whisked to combine, and set aside momentarily.
Unsalted butter is beaten on medium speed for 3 minutes in a stand mixer or with a hand mixer. Granulated sugar and brown sugar are added to the butter and beaten on medium for a few more minutes. Two eggs are added one at a time and beaten long enough to incorporate.
The reserved milk mixture is added to the stand mixer and beaten on low long enough to incorporate.
The bowl is removed from the stand mixer and the reserved flour mixture is folded in two batches.
Half the cake batter is transferred to the prepared baking pan. Half the reserved crumble is sprinkled evenly on top of the cake batter. Half the fresh blueberries are sprinkled over the crumble. The remaining cake better is dolloped over the blueberries and spread evenly with an offset spatula. The remaining crumble and blueberries are sprinkled over the top of the cake batter.
The blueberry coffee cake is baked for 50 minutes, or until a toothpick inserted in the center of the cake comes out clean.
The cake is cooled in the pan on a wire rack. The cake can be cut in the pan, or removed using the parchment paper handles.
The cake can be stored in an airtight container in refrigerator for several days.
