These gluten free lemon poppy seed muffins are bright, tender, and topped with a sweet lemon glaze. Perfect for brunch or an afternoon treat the whole family will love.
Preheat the oven to 375 degrees F. Line a 12-cup muffin tin with paper liners or grease well with nonstick spray.
In a medium bowl, whisk together the gluten free flour, poppy seeds, baking powder, baking soda, and salt.
In a large bowl, whisk together the melted butter and sugar until combined. Add the eggs one at a time, whisking after each. Stir in the sour cream, lemon juice, lemon zest, and vanilla until smooth.
Add the dry ingredients to the wet ingredients and fold gently with a spatula until just combined. Do not overmix. Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.
Bake for 18 to 22 minutes, until the tops are lightly golden and a toothpick inserted in the center comes out clean. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack.
While the muffins cool, whisk together the powdered sugar, lemon juice, and lemon zest until a smooth, pourable glaze forms. Drizzle generously over the warm muffins and let the glaze set for about 10 minutes before serving.
