Ingredients Needed
I recommend using the following ingredients to make these easy lemon poppy seed muffins. The brands mentioned below are favorites of mine, but please use what you have on hand or what is readily available in your area.
- Lemon Juice and Lemon Zest. Fresh is best over bottled when it comes to this recipe. And the lemon zest is a must. Save the leftover lemon juice for the lemon glaze and reserve the lemon zest for garnish.
- Lemon Extract. You can also use lemon extract paste as a 1:1 substitution. My favorite is from Taylor & Colledge. This is an optional ingredient, but the extract or extract paste helps elevate that lemon flavor even more.
- Whole Milk. Any brand of whole milk dairy is best here. My brand is a somewhat local Central PA favorite—Apple Valley Creamery. Their milk comes in glass bottles, which you return when you get a fresh bottle of milk. It’s very reminiscent of my childhood.
- Sour Cream. Full-fat sour cream is best here. And you really can’t go wrong with any brand. Some of my favorites include Daisy, Breakstone’s, and the generic brand from the grocery store.
- Poppy Seeds. I have used Nature’s Promise (the organic brand of Giant grocery store) and Morton & Bassett.
- Powdered Sugar. This is used only for the lemon glaze. Domino Sugar, or even a generic brand from your local grocery store, will work perfectly.
For quantities and instructions, please see the recipe card below.
Substitutions
Below are two substitutions you can make to this bakery-style lemon poppy seed muffin recipe.
- Sour Cream. In place of full-fat sour cream, you can use full-fat plain Greek yogurt.
- Lemon Extract. Instead of lemon extract, you can use lemon extract paste. It packs the same amount of added flavor but in a paste form. You can also brush the lemon extract paste on the muffins instead of the lemon syrup!
Please note that I did not test this recipe with any additional flour, sugar, or egg substitutes.
How to Make the Recipe
Below is a quick overview of how to make these homemade lemon poppy seed muffins. For the full printable recipe, which can be made using US customary or metric measurements, visit the recipe card below.
Recipe Tip: Before beginning this lemon poppy seed muffin recipe, it’s best to soak the poppy seeds in warm water for at least 1 hour, or, preferably, overnight. Then drain with a sieve before adding them to the muffin batter. This avoids any unwanted crunchiness, and the soaking allows the mild nutty flavor to come through.
Step 1. Sift the dry ingredients together. You can sift the flour and then whisk in the remaining dry ingredients.
Step 2. Rub the sugar and lemon zest together. Doing so will really bring out the best lemon flavor in these lemon poppy seed muffins. Set to the side.
Recipe Tip: Go ahead and melt the unsalted butter now, before adding it to the mixture in Step 5, as it needs just a minute or two to cool slightly.
Step 3. Mix the wet ingredients together. These ingredients include sour cream, whole milk, lemon juice, the extracts, and eggs. Mix them together until combined, then add the sugar-zest mixture.
Step 4. Add in the dry mixture. With a spatula, only stir about halfway.
Step 5. Add in the melted butter and poppy seeds. Stir the muffin batter just until combined. If a few streaks of the dry mixture remain, that is okay. Cover, then refrigerate the muffin batter for 30 to 45 minutes. The batter will be a thick but light consistency after refrigeration.
Step 6. Fill each muffin liner with the batter, then bake. Fill almost to the top. Bake for 18-20 minutes at 400ºF. The muffin tops should spring back when lightly pressed. Let them sit in the tin for 5-10 minutes, then move to a cooling rack.
Recipe Tip: For more lemon flavor, you can brush a simple honey-lemon syrup over the tops of the just-baked muffins. It’s one tablespoon of lemon juice whisked together with one tablespoon of honey in a small bowl. Then apply with a pastry brush. I added this simple syrup to my Small Batch of Lemon Cupcakes after bringing them out of the oven. So yummy!
Step 7. Whisk together the lemon glaze. This glaze consists of only two ingredients and comes together quickly, so you can wait until the muffins are done baking to whisk it together.
Step 8. Drizzle the glaze over the top of each muffin. It’s best to drizzle the glaze on cooled or somewhat cooled muffins. I used a spoon, but you can also dip them into the glaze.
Garnish Suggestions
You can easily enjoy these fluffy lemon muffins plain, but here are a few topping or garnish suggestions to make them a little extra special!
- Sparkling Sugar. Sprinkle on before baking for a sweet, sparkling touch to your muffins.
- Lemon Syrup. Brush this on immediately after removing the muffins from the oven. As stated above, you can also use lemon extract paste.
- Lemon Glaze. A simple two-ingredient glaze that elevates the look and taste.
- Lemon Zest. While prepping your lemons for the muffin batter, grate a little more zest for a pretty garnish!
Storage
Store these lemon poppy seed muffins in an airtight container for up to 3 days at room temperature or up to 5 days in the refrigerator. Please note that storing the muffins at room temperature or in the refrigerator may cause them to develop mushy tops if the honey-lemon syrup or lemon glaze is applied.
These muffins can also be kept frozen (cooled, then wrapped in plastic wrap, and kept in a freezer bag or container) for up to 3 months. Reheat (from frozen) in a 350ºF pre-heated oven for 10-12 minutes.
Top Tips
For the best lemon poppy seed muffins, check out these helpful tips before starting the recipe. These tips will also be shown in the recipe card below.
- Soak the poppy seeds. To avoid crunchy poppy seeds in your lemon poppy seed muffins and let them reach their full flavor potential, I recommend soaking them in warm water for at least 1 hour, or, for the best results, overnight.
- Sift the flour. For fluffier lemon muffins, I highly recommend sifting your all-purpose flour.
- Rub the lemon zest with the sugar. Doing so really brings out the best lemon flavor in these lemon poppy seed muffins!
- Don’t over-mix the batter. When you over-mix the muffin batter, you can wind up with a tougher-textured muffin when baked. Over-mixing also adds more air to the mixture, creating holes.
- Rest the muffin batter. If time allows, I recommend refrigerating your lemon poppy seed muffin batter (covered) for 30 to 45 minutes, max. You can even let the batter rest overnight if you need to.
- Fill the cupcake liners to the very top. It might seem like a lot, but the muffin batter will rise and form a nice dome shape on top!
- Brush on the lemon honey syrup. This step wasn’t shown above, but if you prefer to skip the lemon glaze topping, you can brush on some lemon honey syrup over the top of each lemon poppyseed muffin right after they’ve come out of the oven. I do this with my small-batch lemon cupcakes recipe, and it’s easy to whisk together and adds an even greater lemon flavor!
- Let the muffins cool before unwrapping. It’s best to let the lemon poppyseed muffins cool slightly (or completely) before unwrapping them to avoid the bottoms sticking to the muffin liners.
Recipe FAQs
Soaking the poppy seeds before adding them to your lemon muffin batter brings out their mild nutty flavor, complementing the lemon nicely. Soaking them also prevents them from being too crunchy when you bite into your lemon poppy seed muffins. I recommend soaking them for at least 1 hour or, preferably, overnight.
I used a #20 yellow scoop, which is equal to about 3 1/4 tablespoons.
Allowing the muffin batter to rest gives the flour’s starches additional time to absorb the moisture from the eggs and other liquids. These starches also undergo expansion, resulting in a stronger, thicker texture in the batter.
During testing, I tried resting the batter for 30 minutes, 45 minutes, and overnight. For me, the results showed no real difference in the height or texture of the baked muffins, which is why I recommend the 30-45 minute mark. But if you need more time, then overnight is fine too.
