Blueberry Brunch Cake

This brunch cake walks the line between coffee cake and dessert. A buttery, sour cream batter laced with poppy seeds and lemon zest gets spread in a springform pan with the batter pushed up the sides to create a well. That well holds a generous layer of blueberries tossed with sugar, flour, and cinnamon.

Sour cream in the batter keeps the crumb impossibly moist and tender. It adds a slight tang that balances the sweetness and plays off the lemon zest beautifully. The poppy seeds scattered throughout give each bite a subtle crunch and nutty flavor you don’t expect.

Building the batter wall up the sides of the pan is the key structural move. It contains the berry filling in the center so you get a distinct layer of fruit sitting on top of cake, not berries sinking to the bottom. The flour tossed with the blueberries thickens their juices during baking so the center sets instead of staying runny.

A simple powdered sugar and milk glaze drizzled over the top once cooled finishes it off with a sweet, glossy touch.

Kitchen Tips

• Spread the batter evenly up the sides. Thin spots will let the filling leak through.
• Use fresh or frozen blueberries. If frozen, don’t thaw them first or they’ll release too much juice.
• The cake is done when the edges pull slightly away from the pan and the filling bubbles in the center.
• Cool in the pan before releasing the springform. The filling needs time to set.

Variations

• Swap blueberries for raspberries or blackberries for a different berry flavor.
• Add almond extract to the batter instead of lemon zest for a nutty twist.
• Top with a streusel crumble instead of the glaze for more texture.
