Follow these simple steps to create your delicious Keto Lemon Blueberry Muffins:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large mixing bowl, combine almond flour, erythritol, baking powder, baking soda, and salt. Stir well to eliminate any lumps.
3. Mix Wet Ingredients: In another bowl, whisk together eggs, almond milk, applesauce, lemon juice, lemon zest, and vanilla extract until combined.
4. Combine Mixtures: Add the wet ingredients to the dry ingredients. Stir until just combined. Avoid over-mixing, as this can make the muffins dense.
5. Fold in Blueberries: Gently fold in the blueberries, ensuring they are distributed evenly throughout the batter.
6. Fill Muffin Liners: Use an ice cream scoop to fill each muffin liner about two-thirds full with the batter.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool: Once baked, remove the muffins from the oven and allow them to cool in the tin for about 10 minutes. Transfer to a wire rack to cool completely.

These steps will guide you in creating muffins that are as delightful to eat as they are to make!
