I love finding simple things that surprise you, and these muffins did just that. I wanted a morning bite that wasn’t boring, something bright and a little stubborn, so I leaned hard on lemon zest and a sprinkle of poppy seeds for that tiny crunchy pop.

I made a regular batch and a keto tweak and honestly both caught me off guard, like why has no one told me this before? They’re the kind of thing you nibble and then wonder if you should eat another, even if you swore you wouldnt.

- Poppy seeds: tiny crunch, mild nutty flavor, they add fiber and healthy fats.
- Lemon zest and juice: bright tart flavor, vitamin C, it lifts the sweetness.
- Unsalted butter: adds richness and moisture, mostly saturated fat, makes crumb tender.
Keto Lemon Poppy Seed Muffins:
- Blanched almond flour: low carb, high in healthy fats and protein, it’s filling.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven and prep tin: heat oven to 375F for the classic muffins or 350F for the keto version, place rack in center, line a 12 cup muffin tin with papers or grease each cup and set aside.

2. Mix dry ingredients for classic: whisk 2 cups all purpose flour, 1 cup granulated sugar, 2 teaspoons baking powder, 1/2 teaspoon fine salt, 2 tablespoons poppy seeds and the zest of 2 lemons in a large bowl. For keto: in a separate bowl stir 2 1/2 cups blanched almond flour, 1/3 cup powdered erythritol, 2 teaspoons baking powder, 1/4 teaspoon fine salt, 2 tablespoons poppy seeds and the zest of 2 lemons.

3. Combine wet ingredients for classic: in another bowl whisk 2 large eggs, 1/2 cup melted unsalted butter cooled a bit, 2/3 cup milk, 1/4 cup fresh lemon juice and 1 teaspoon vanilla extract until blended. For keto: beat 3 large eggs with 1/3 cup melted butter or coconut oil, 1/4 cup unsweetened almond milk or heavy cream, 1 tablespoon fresh lemon juice and 1 teaspoon vanilla.

4. Add wet to dry: pour the wet mixture into the dry for whichever version you are making and stir gently until just combined, scraping the bowl. Do not overmix, it should be thick but pourable for classic and noticeably thicker for keto. It’s okay if there are a few small lumps.

5. Let keto batter rest if you have time: almond flour soaks up liquid fast so let keto batter sit 5 minutes to hydrate, then give it one quick stir. For classic batter no rest needed.

6. Portion the batter: use an ice cream scoop or large spoon to fill each muffin cup about 3 quarters full for classic. For keto fill cups almost full because they do not rise quite the same. Sprinkle a few extra poppy seeds or a pinch of zest on top if you want.

7. Bake and check: bake classic muffins 18 to 20 minutes at 375F until tops are golden and a toothpick comes out clean. Bake keto muffins 20 to 25 minutes at 350F until set and a toothpick comes out mostly clean and edges are lightly golden. Rotate the pan once halfway through if your oven runs hot.

8. Cool: let muffins sit in the pan 5 minutes then transfer to a wire rack to cool completely before glazing. Cooling prevents the glaze from running off and keeps texture right.

9. Make the glaze if desired: classic glaze whip 1 cup powdered sugar with 2 tablespoons fresh lemon juice and 1 tablespoon milk until smooth, add more milk a few drops at a time to reach drizzling thickness. Keto glaze beat 4 ounces softened cream cheese with 1/4 cup powdered erythritol and 1 tablespoon fresh lemon juice until smooth, stir in 1 to 2 tablespoons heavy cream to thin if needed then chill briefly so it sets on the muffins.

10. Store and tips: store classic muffins in an airtight container at room temp up to 2 days or refrigerate for longer, keto muffins keep well refrigerated up to 4 days especially if glazed. Both freeze well unglazed up to 2 months; thaw at room temp or warm a bit in the oven. Tip wise use room temperature eggs for better rise, zest before juicing the lemons, measure almond flour by spooning and leveling, and remember less mixing means more tender muffins.

Equipment Needed

1. Oven (preheat to 375 F for classic or 350 F for keto)
2. 12 cup muffin tin
3. Paper liners or nonstick cooking spray
4. Large mixing bowl and a medium mixing bowl (one for dry, one for wet)
5. Measuring cups and spoons (including 1/4 cup and teaspoons)
6. Whisk and rubber spatula
7. Microplane or zester (for lemon zest)
8. Ice cream scoop or large spoon for portioning
9. Wire cooling rack and a toothpick to check doneness

FAQ

Q: How do I know when the muffins are done? A: Stick a toothpick into the center. If it comes out with a few moist crumbs the muffins are done, not wet batter. Tops should spring back when lightly pressed. Classic muffins usually bake for 18 to 22 minutes at 350 F, keto ones often need 22 to 28 minutes at the same temp because almond flour bakes differently.

Q: Can I swap ingredients like milk or butter? A: Yep. For the classic recipe you can use yogurt or buttermilk instead of milk, and a neutral oil instead of butter for a moister crumb. For the keto version melted coconut oil works fine instead of butter, and heavy cream or unsweetened almond milk can replace the almond milk. Measurements stay about the same.

Q: Why did my muffins turn out dense or gummy? A: Most likely overmixing the batter or using too much liquid. For almond flour muffins remember that almond flour holds more moisture and makes a denser crumb, so follow the recipe and don't overbeat. Also measure flour by spooning it into the cup then leveling, not scooping straight with the cup.

Q: Can I make these dairy free or vegan? A: Dairy free is doable by swapping butter for oil or coconut oil and using plant milk. Vegan is harder because eggs give structure and lift. You can try flax or chia eggs but expect a different, denser texture and you may need to tweak baking times and add a little extra leavening.

Q: How should I store and freeze them? A: Store classic muffins at room temp in an airtight container for up to 2 days, or in the fridge up to 5 days if glazed. Keto muffins keep in the fridge 4 to 5 days because of the eggs and almond flour. Freeze any type in a freezer bag for up to 3 months. Thaw at room temp or warm briefly in the microwave.

Q: Can I make these in a loaf pan or as mini muffins? A: Yes. For a loaf bake at the same temp but expect a much longer time, usually 45 to 60 minutes, check with a toothpick. For mini muffins reduce bake time to about 10 to 14 minutes. Keep an eye on them because sizes change timing a lot.

Lemon Poppy Seed Muffins Recipe Substitutions and Variations

All purpose flour
- Whole wheat pastry flour — use 1:1; muffins will be a bit denser and nuttier, add a splash more milk if batter seems stiff
- Cake flour — use 1:1 for a softer, more tender crumb (batter will be lighter)
- Gluten free all purpose blend (with xanthan) — usually 1:1, check package notes and maybe add a little extra liquid if batter feels dry
Granulated sugar
- Honey — use about 3/4 cup honey for 1 cup sugar, reduce other liquids by ~3 tbsp and bake a little cooler so tops dont brown too fast
- Maple syrup — use ~3/4 cup, same break as honey, gives maple note to the muffins
- Coconut sugar — 1:1 swap, darker caramel flavor and browns quicker
Milk
- Buttermilk — 1:1, adds tang and makes muffins extra tender (batter may be a touch thinner)
- Plain yogurt thinned with water or milk (equal parts yogurt and water) — use to equal the milk amount, gives richness
- Unsweetened almond milk or other plant milk — 1:1 for a dairy free option
Melted unsalted butter
- Neutral oil (canola, vegetable, light olive) — swap roughly 1:1 by volume for melted butter, muffins will be moister
- Light coconut oil — 1:1, use melted and expect a mild coconut note
- Unsweetened applesauce — replace up to half the butter with applesauce to cut fat, muffins will be softer and slightly less rich

Pro Tips

1) Weigh or spoon and level your flours, don’t pack them into the cup. For almond flour scoop gently and let the batter sit about five minutes so it can absorb liquid, otherwise the texture ends up gummy.

2) Use room temp eggs and let melted butter cool a little before adding, hot butter will start cooking the eggs and give you a curdled, uneven batter. If you accidentally add hot butter stop mixing and let it cool for a bit, then continue.

3) Don’t overmix, stir just until the dry streaks mostly disappear, a few small lumps are totally fine. Overworking the batter makes muffins tough and flat.

4) Portion with an ice cream scoop so all muffins bake the same, and fill the cups consistently because fill level changes bake time a lot. If your oven runs hot rotate the pan halfway and test centers with a toothpick.

5) Cool completely before glazing so the glaze doesn’t run off, and if using a cream cheese glaze chill it briefly to help it set. Store classic muffins at room temp up to two days, keto muffins keep longer in the fridge up to four days, both freeze fine unglazed.
