Ingredients

For the Muffins

• 2 cups Gluten Free 1-to-1 Baking Flour
• 2 tbsp Poppy Seeds
• 1 1/2 tsp Baking Powder
• 1/4 tsp Baking Soda
• 1/2 tsp Salt
• 1/2 cup Unsalted Butter, melted
• 3/4 cup Granulated Sugar
• 2 Large Eggs
• 1/2 cup Sour Cream
• 1/4 cup Fresh Lemon Juice
• 2 tbsp Lemon Zest
• 1 tsp Vanilla Extract

For the Lemon Glaze

• 1 cup Powdered Sugar
• 2 tbsp Fresh Lemon Juice
• 1 tsp Lemon Zest

How to Make

Step 1

Preheat the oven to 375 degrees F. Line a 12-cup muffin tin with paper liners or grease well with nonstick spray.

Step 2

In a medium bowl, whisk together the gluten free flour, poppy seeds, baking powder, baking soda, and salt.

Step 3

In a large bowl, whisk together the melted butter and sugar until combined. Add the eggs one at a time, whisking after each. Stir in the sour cream, lemon juice, lemon zest, and vanilla until smooth.

Step 4

Add the dry ingredients to the wet ingredients and fold gently with a spatula until just combined. Do not overmix. Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.

Step 5

Bake for 18 to 22 minutes, until the tops are lightly golden and a toothpick inserted in the center comes out clean. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack.

Step 6

While the muffins cool, whisk together the powdered sugar, lemon juice, and lemon zest until a smooth, pourable glaze forms. Drizzle generously over the warm muffins and let the glaze set for about 10 minutes before serving.

My Tips

Don’t Skip the Sour Cream

The sour cream is doing a lot of heavy lifting in this recipe. Gluten free baked goods can sometimes turn out dry or crumbly, and the sour cream adds moisture and fat that keeps these muffins soft and tender.

If you don’t have sour cream, full-fat Greek yogurt works as a swap. Just make sure it’s plain and not flavored.

Low-fat or fat-free versions won’t give you the same result. You want that richness to balance out the lemon juice and keep the texture right.

Zest Before You Juice

You need both lemon zest and lemon juice for the muffins and the glaze, so always zest your lemons first before you cut and juice them. Trying to zest a lemon that’s already been cut in half is messy and frustrating.

Use a microplane or fine grater and only zest the bright yellow outer layer. The white part underneath (the pith) is bitter and will throw off the flavor of your muffins and glaze.

You’ll need about 3 medium lemons to get enough zest and juice for both the batter and the glaze.

Let the Melted Butter Cool Down a Bit

After you melt the butter, give it about 5 minutes to cool before you whisk it with the sugar and eggs. If it’s too hot, it can start to cook the eggs when you add them, and you’ll end up with little scrambled bits in your batter.

It should feel warm to the touch but not steaming. Think warm, not hot.

FAQ

Can I substitute the sour cream with something else?

You can use full-fat Greek yogurt as a 1-to-1 swap for the sour cream. It gives the muffins the same moisture and tender crumb because it has a similar fat content and tanginess.

If you need a dairy-free option, coconut cream or a thick dairy-free yogurt can also work, though the flavor will be slightly different.
