• 1/2 cup (64g) coconut flour
• 4 tbsp (48g) granulated erythritol or sweetener of choice
• 1 tsp (4g) baking powder

2. In a large bowl, whisk together the melted butter, granulated sweetener, coconut flour, baking powder, vanilla extract, lemon juice, and lemon zest until well combined.
3. Add the eggs one at a time, whisking thoroughly after each addition until the batter is smooth.
4. Gently fold in the fresh blueberries, being careful not to crush them.

Pro Tips

• For the best texture, ensure your eggs are at room temperature before mixing. This helps them combine more evenly with the other .
• Different keto sweeteners have varying levels of sweetness. Taste a tiny bit of the batter (before adding eggs) to adjust the sweetness to your preference.
• If using frozen blueberries, toss them in 1 teaspoon of coconut flour before folding them into the batter. This prevents them from sinking and turning the batter purple.
• Store leftover muffins in an airtight container in the refrigerator for up to 5 days. Gently warm them in the microwave for 10-15 seconds before enjoying.

FAQ

Q: Can I use frozen blueberries for this recipe
A: Yes, you can use frozen blueberries. For best results, toss them in 1 teaspoon of coconut flour before folding them into the batter. This helps prevent them from sinking and turning the batter purple.

Q: What other keto sweeteners can I use instead of erythritol
A: You can use your favorite granulated keto-friendly sweetener. Since sweetness levels vary between brands and types, it’s a good idea to taste the batter before adding the eggs to adjust it to your preference.

Q: How should I store these keto lemon blueberry muffins
A: Store leftover muffins in an airtight container in the refrigerator for up to 5 days. For the best taste and texture, you can gently warm them in the microwave for 10-15 seconds before serving.

Q: Can I substitute the coconut flour with almond flour
A: This recipe is specifically formulated for coconut flour, which is very absorbent. Substituting it with almond flour would require significant changes to the liquid and egg quantities, so it is not recommended without modifying the entire recipe.
