Ingredients

2 1/2 cups (320g) all purpose flour*
1 cup (200g) granulated sugar
2 1/2 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
2 tbsp poppy seeds
1/2 cup (110g) unsalted butter, melted
2 tbsp vegetable oil
2 large eggs, room temperature
1/4 cup (65g) sour cream**, room temperature
2 tsp vanilla extract
1/4 tsp almond extract (or lemon extract)
2 tbsp lemon zest (about 2 lemons)
1 tbsp lemon juice (about 1/2 lemon)
1 cup (255ml) milk, room temperature
1/2 cup (118ml) fresh lemon juice (about 4 lemons)
1/2 cup (100g) granulated sugar (for syrup)
Lemon peel from 1 lemon (for syrup)

Instructions

Step 1: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and poppy seeds.
Step 2: In another bowl, mix together the melted butter, vegetable oil, eggs, sour cream, vanilla extract, almond or lemon extract, lemon zest, lemon juice, and milk until smooth.
Step 3: Pour the wet mixture into the dry ingredients and gently fold together using a rubber spatula until just combined.
Step 4: Cover the bowl with plastic wrap and let the batter rest at room temperature for 1 hour to develop fluffiness.
Step 5: Meanwhile, prepare the lemon simple syrup. Combine the fresh lemon juice and 1/2 cup sugar in a saucepan over medium heat.
Step 6: Bring to a boil, then reduce heat and simmer for 10 minutes until the sugar fully dissolves.
Step 7: Carefully peel the zest from 1 lemon avoiding the white pith and place it in a heat-safe bowl.
Step 8: Remove the syrup from heat and pour it over the lemon peel. Let it cool at room temperature while the batter rests.
Step 9: Near the end of the resting time, preheat the oven to 425°F (220°C). Line a cupcake tin either with 11 paper liners or with 6 liners spaced evenly for taller muffin tops.
Step 10: Using a large 2 oz scoop or about 1/4 cup measuring cup, fill each muffin liner to the top to maintain the fluffiness from resting.
Step 11: Bake for 8 minutes at 425°F, then reduce the temperature to 350°F (175°C) and bake for another 8-10 minutes until golden and a toothpick inserted comes out clean.
Step 12: If baking in two batches, remember to reset the oven to 425°F before baking the second batch.
Step 13: When muffins come out of the oven, brush them generously with the cooled lemon simple syrup for extra moisture and flavor.
Step 14: Let the muffins cool in the pan for 5 minutes, then transfer to a rack to cool for 15-20 minutes. Optionally, sprinkle with more poppy seeds and enjoy warm.

Tips & Variations

For a dairy-free version, substitute sour cream with coconut yogurt or a non-dairy sour cream alternative.
If you prefer a stronger lemon flavor, increase the lemon zest or add a bit more lemon extract.
Use fresh lemons for best flavor; bottled lemon juice won’t give the same bright, natural taste.
Resting the batter really helps develop a lighter, fluffier muffin — don’t skip this step!

Storage

Store leftover muffins in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. To reheat, warm in a microwave for 15-20 seconds or in a 300°F oven for 5 minutes. These muffins also freeze well; wrap individually and freeze for up to 3 months. Thaw before reheating.

FAQs

Can I use frozen lemon juice for the syrup?

Fresh lemon juice is best for bright flavor, but in a pinch, frozen lemon juice can be used. Thaw completely before using, though the taste might be slightly less vibrant.

Why do the muffins need to rest before baking?

Resting the batter at room temperature allows the baking powder and baking soda to activate fully, resulting in fluffier, lighter muffins with better rise and texture.
