ยผ cup Coconut Flour
ยฝ cup Erythritol/Monk Fruit Blend
2 teaspoons Baking Powder
ยผ teaspoon Salt
4 Large Eggs
ยฝ cup Melted Butter or Coconut Oil
ยผ cup Unsweetened Almond Milk
ยผ cup Fresh Lemon Juice

Instructions
- Preheat your oven to 350ยฐF (175ยฐC). Line a 12-cup muffin tin with paper liners or grease it well

- In a separate medium bowl, whisk the eggs, melted butter (or coconut oil), almond milk, lemon juice, lemon zest, and vanilla extract until smooth

- Remove the muffins from the oven and let them cool in the muffin tin for 5 minutes before transferring them to a wire rack to cool completely
Notes
Ensure all wet ingredients, especially the eggs, are at room temperature for a smoother batter.
Do not overmix the batter; mix just until the ingredients are combined to prevent tough muffins.
For an extra pop of lemon, brush the warm muffins with a simple glaze made from powdered erythritol and a tiny bit of fresh lemon juice immediately after baking.
Avoid opening the oven door too early during baking to prevent the muffins from sinking.
Store cooled muffins in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
For longer freshness, freeze cooled muffins in a freezer-safe bag or container for up to 2-3 months.
To reheat, microwave refrigerated muffins for 15-30 seconds or frozen muffins for 45-60 seconds. Alternatively, warm them gently in a toaster oven for a crispy exterior.
