Preheat the oven to 400F and grease a 24 mini-muffin pan with butter or spray.
In a large bowl, combine the flour, sugar, baking powder, and salt. Make a well in the middle and add the milk, butter, egg, vanilla, and lemon zest. Mix to combine the batter until there are no clumps.
Fill each muffin cup ¾th full and top with 3 blueberries each, pushing them slightly down into the batter.
Bake for 12 to 14 minutes until the tops are golden brown. Remove them from the oven and allow them to cool for 5 minutes prior to serving.
For the glaze, in a small bowl, whisk ¼ cup confectioners’ sugar and 1 ½ teaspoon of milk until smooth. Drizzle over the mini muffins and enjoy.
Notes
If making this recipe gluten-free, I recommend using a 1:1 gluten-free all-purpose flour mix.
Nutrition information is calculated without the glaze.
Use the right baking powder: Since pancake batter naturally has a mild, neutral flavor, it's important to use aluminum-free baking powder. The metallic flavor will ruin the taste, especially in fluffy pancake recipes that call for 2 or more teaspoons. Trust me on this one.
