Preheat your oven to a warm 400°F (200°C). Line a 12-cup muffin tin with paper liners and give them a quick spray with cooking oil – this ensures your delicious muffins won't stick!
In a large mixing bowl, combine the dry ingredients for your muffins: the almond flour, baking soda, salt, and granular sweetener. Give them a good whisk to ensure everything is evenly mixed.
Now, add the wet ingredients to your dry mix: the beaten eggs, Greek yogurt, vanilla extract, a splash of lemon juice, and the bright lemon zest. Stir everything together gently until just combined and smooth. Be careful not to overmix!
Carefully divide this lovely batter among your 12 prepared muffin cups.
Bake these beauties in the preheated oven for 15-18 minutes. You'll know they're ready when a toothpick inserted into the center comes out clean. Let them cool completely before you get to the glazing fun.
While your muffins are cooling, whip up the easy lemon glaze: In a small bowl, combine the powdered sweetener and the remaining lemon juice. Whisk until it's wonderfully smooth.
Once the muffins are completely cool, drizzle the delightful lemon glaze over the top of each one with a spoon. Now they're ready to be enjoyed as a healthy and satisfying treat!
