Polenta Blueberry Cakes

Cornmeal turns these miniature blueberry cakes into something between a muffin and a shortcake. Three tablespoons isn’t enough to make them gritty, but it’s plenty to add a subtle corn sweetness and a rustic crumb that regular flour cakes can’t match.

The key move is tossing the blueberries in a tablespoon of flour before folding them into the batter. That light coating prevents them from sinking to the bottom of each muffin and keeps them suspended right where you want them. Fresh or frozen both work, but don’t thaw frozen berries first or they’ll bleed purple streaks through the batter.

Buttermilk provides the classic tang that pairs with lemon zest and a drizzle of lemon glaze. Alternating buttermilk with dry ingredients (ending with dry) is the traditional cake-mixing method that keeps the batter smooth without overdeveloping gluten.

The glaze goes on while the cakes are still warm so it soaks into the crumb instead of just sitting on top. Two dozen miniature muffins disappear fast at brunch, tea, or alongside afternoon coffee.

Pro Tips

• Tossing berries in flour is non-negotiable for even distribution. Skip the step and you get all berries at the bottom.
• Don’t overbake. 14 minutes is the target. These dry out fast because mini-muffin cups are small.
• Fill each cup two-thirds full, not all the way. They puff up during baking and overflow easily.
• Cool in the pan for 5 minutes before removing, then transfer to a rack so the bottoms don’t steam.

Variations

• Swap blueberries for raspberries, blackberries, or chopped strawberries.
• Add a teaspoon of fresh thyme or rosemary to the batter for an herbal note.
• Glaze with orange juice and orange zest instead of lemon for a citrus variation.
