Ingredients
-
1 ¾ cups unbleached all-purpose flour
-
¼ cup fine cornmeal
-
¾ cup sugar, plus more for sprinkling (optional)
-
2 teaspoons baking powder
-
1 teaspoon kosher salt (we use Diamond Crystal)
-
4 ounces rhubarb, cut into a ½-inch dice (1 cup)
-
4 ounces blueberries (a scant 1 cup)
-
2 large eggs, room temperature
-
¾ cup whole or 2 percent milk, room temperature
-
1 stick unsalted butter, melted and slightly cooled
-
1 teaspoon pure vanilla extract
Directions
-
Preheat oven to 350°F. Line a standard 12-cup muffin tin with baking cups. In a medium bowl, whisk together flour, cornmeal, sugar, baking powder, and salt. Reserve about 3 tablespoons each rhubarb and berries, then stir the rest into mixture. Create a well in center of mixture; add eggs and whisk. Whisk in milk, butter, and vanilla.
-
Divide batter evenly among muffin cups, about 1/3 cup each (they will be very full). Press a few pieces of reserved fruit into top of each, then sprinkle with sugar. Bake until tops spring back when lightly touched, 25 to 30 minutes. Let cool 5 minutes in tin, then remove muffins and transfer to a wire rack; let cool completely, about 30 minutes.
Cook's Notes
The reserved rhubarb and berries are added to the tops before baking so they'll be visible in the finished muffins.
