In a large bowl, whisk together all the dry ingredients. Set aside.
2 cups gluten free 1-to-1 flour, 2 tsp baking powder, ½ tsp baking soda, ½ tsp kosher salt, 2 tbsp poppyseeds
In another large bowl, whisk together all the wet ingredients for several minutes until smooth and no yogurt chunks remain.
2 large eggs, ½ cup unsalted butter, ¼ cup full-fat plain greek yogurt, ¼ cup milk of choice, ¾ cup maple syrup, 2 tbsp fresh lemon juice, 2 tbsp lemon zest, 2 tsp vanilla extract
Pour the wet ingredients into the dry ingredients and use a spatula to stir until just combined. Don't over-mix!
Cover the bowl with plastic wrap and let it rest at room temperature for 1 hour. The baking powder will activate during this time and help the muffins become fluffier and taller!
When there's about 15 minutes of resting time left, preheat your oven to 425F and place paper liners into your muffin tin cavities.
After the hour of resting time, gently scoop out the muffin batter and place it into the lined muffin tin. This recipe yields 12 small muffins but if you want larger ones, instead spread the batter between 10-11 muffin cavities.
Transfer to the oven to bake for 8 minutes. Then, reduce the oven temperature to 350F and continue cooking for about 8 more minutes or until the tops are lightly golden and a toothpick comes out clean.
Let the muffins cool in the muffin tin for 5 minutes before transferring to a wire rack to cool completely. Enjoy!
