Ingredients

• ¾ cup / 84g almond flour
• ⅓ cup / 67g Erythritol
• ¼ cup / 28g flaxseed meal
• 1 tbsp / 12g baking powder
• 2 tbsp / 18g poppy seeds
• ¼ cup / 57g butter, melted
• 3 large eggs
• ¼ cup / 60ml heavy cream
• 3 tbsp / 45ml fresh lemon juice

• 20 drops liquid stevia or monk fruit sweetener

Instructions

1. Directions
2. Preheat your oven to 345°F (175°C) and line a 12-cup muffin tin with paper liners.
3. In a large bowl, whisk together the almond flour, Erythritol, flaxseed meal, baking powder, and poppy seeds.
4. In a separate medium bowl, whisk the melted butter, eggs, heavy cream, lemon juice, lemon zest, vanilla, and liquid sweetener until well combined.
5. Pour the wet into the dry and stir until just combined. Do not overmix.
6. Divide the batter evenly among the 12 prepared muffin cups.
7. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.

Pro Tips

• For a smoother, more uniform batter, use room temperature eggs and heavy cream. This helps the emulsify better and results in a superior texture.
• Once you combine the wet and dry , mix only until they are just incorporated. Overmixing develops the gluten in the flour, which can lead to dense, tough muffins.
• For an extra burst of lemon flavor, whisk together powdered Erythritol with a little lemon juice to create a simple sugar-free glaze. Drizzle over the completely cooled muffins.

FAQ

Q: How many net carbs are in one muffin
A: Each Keto Lemon Poppy Seed Muffin contains just 1.7g of net carbs, making it an excellent low-carb option for a keto diet.

Q: Can I use coconut flour instead of almond flour in this recipe
A: This recipe is specifically formulated for almond flour. Coconut flour is much more absorbent and cannot be substituted on a 1:1 basis without altering the other liquid ingredients. For the best, moist texture, we recommend sticking with almond flour.

Q: How should I store these keto muffins
A: Store the completely cooled muffins in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. They also freeze well for longer storage.

Q: Is it okay to use bottled lemon juice
A: For the brightest and most authentic lemon flavor, fresh lemon juice and zest are highly recommended. Bottled juice lacks the vibrant taste and aroma that fresh lemons provide.
