Lemon Poppy Seed Muffins
Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
- In a large mixing bowl, whisk together the almond flour, erythritol, poppy seeds, baking powder, and salt until well combined.
- In a medium bowl, whisk together the eggs, melted butter, lemon juice, lemon zest, and vanilla extract until smooth. The mixture will be bright and fragrant.
- Pour the wet ingredients into the dry ingredients and stir with a rubber spatula until just combined. The batter will be thick but scoopable.
- Divide the batter evenly among the 12 muffin cups, filling each about 2/3 full.
- Bake for 18-20 minutes, until the tops are light golden and a toothpick inserted into the center comes out clean.
- Allow muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely before glazing.
- Optional glaze: Whisk together the powdered erythritol and lemon juice until smooth. Drizzle over the cooled muffins and let set for 5 minutes before serving.

Let us know how it was!Chef’s Tips for Perfect Lemon Poppy Seed Muffins
Zest Before You Juice: Always zest your lemons before cutting them open. It’s nearly impossible to zest a juiced lemon half. You’ll need about 2 lemons for the zest and 1 for the juice.
Avoid the Bitter Pith: Only zest the bright yellow outer layer of the lemon. The white pith underneath is bitter and will ruin the fresh, bright flavor you’re after. Use a microplane for the finest zest.
Room Temperature Eggs: Cold eggs can cause the melted butter to seize into clumps. Set eggs out 30 minutes before baking, or place them in warm water for 5 minutes.
Skip the Glaze for Meal Prep: The optional glaze is delicious but softens over time. For meal prep, store muffins unglazed and add the glaze just before serving for the best texture.
Boost the Lemon: Want more citrus punch? Add 1/4 teaspoon of pure lemon extract to the wet ingredients. It intensifies the lemon flavor without adding carbs.
📦 Storage & Serving Suggestions
Room Temperature: Store unglazed muffins in an airtight container for up to 3 days. The lemon flavor actually intensifies on day two.
Refrigerator: For longer storage, refrigerate for up to 1 week. Bring to room temperature or warm briefly before serving.
Freezer: Freeze unglazed muffins individually wrapped for up to 3 months. Thaw overnight in the fridge or microwave for 30 seconds. Add glaze after thawing.
Meal Prep: Bake a batch on Sunday and store unglazed. Grab one each morning for a quick breakfast, or pack for work as an afternoon snack.
Serving Ideas: Pair with a cup of Earl Grey tea, or enjoy as an afternoon snack with Greek yogurt.
Lemon Poppy Seed Muffins FAQs
Can I use bottled lemon juice instead of fresh?
Fresh is best for flavor, but bottled works in a pinch. Use the same amount of bottled juice, but you’ll miss out on the fresh zest, which provides most of the lemon flavor. Consider adding 1/4 teaspoon lemon extract to compensate.
Why are my muffins bitter?
Bitter lemon muffins usually mean you zested too deeply and got the white pith. Only zest the bright yellow outer layer. A microplane gives you the finest zest without reaching the pith.
Does the glaze add carbs?
The erythritol glaze adds minimal carbs, less than 0.5g per muffin. If you’re tracking macros strictly, skip the glaze. These muffins are delicious either way.
Can I make these nut-free?
Almond flour is essential for the texture of these muffins. For a nut-free version, you’d need a completely different recipe using sunflower seed flour, which behaves differently and may turn green due to a reaction with baking powder.
