Preheat the oven to 350℉. Line a muffin tin with cupcake liners and set aside.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined. Set aside.
2 1/2 cups all purpose flour, 1 cup granulated sugar, 2 tsp baking powder, 1/2 tsp baking soda, 1/2 tsp salt
In a separate bowl, whisk the melted butter, eggs, milk, greek yogurt, lemon extract, lemon juice, and lemon zest until well combined.
1/2 cup unsalted butter, 2 large eggs, 1 cup whole milk, ⅓ cup full-fat greek yogurt, 1 tsp lemon extract, 2 tbsp lemon zest, 2 tbsp lemon juice
Pour the wet ingredients into the dry and use a rubber spatula to mix until just combined. Be careful not to overmix, the batter should be thick and lumpy.
Pour the batter evenly into the prepared muffin pan, filling each ¾ of the way full.
Bake the muffins for 15-17 minutes, or until a toothpick inserted in the middle of a muffin comes out clean.
Allow the muffins to cool in the pan for about 5 minutes before removing them. Place them on a wire cooling rack to cool completely.
Make the lemon glaze by mixing together the powdered sugar and lemon juice until smooth. Drizzle over the tops of the cooled muffins & enjoy!
1 cup powdered sugar, 2 tbsp lemon juice
