This recipe is inspired by Madeline's love for organizing events and her lively morning meet-ups with friends where she'd likely serve something as delightful and colorful as these muffins.
Preheat oven to 375°F.
In a large bowl, mix flour, sugar, baking powder, and salt.
In another bowl, whisk milk, melted butter, and egg.
Combine wet and dry ingredients, then fold in blueberries.
Divide batter into muffin tins and bake for 20-25 minutes.
