Why You’ll Love This Lemon Blueberry Muffin Recipe
A warm lemon blueberry muffin with a sweet glaze drizzled over the top is one of my favorite single serving recipes. It bakes in a single 10-ounce ramekin in about 30 minutes, and the glaze gets whisked together while the muffin cools slightly so it stays on top instead of melting into the crumb.
The crumb bakes up light and fine, with sweet blueberries baked through and lemon coming through in both the muffin itself and the glaze. I use both lemon zest and lemon juice in this recipe because the zest gives the muffin its fresh lemon flavor when it bakes, and the juice gives it the tart bite. Without both, you only get half the brightness.
Any extra lemons can go into our small batch lemon bars, lemon meringue pie for one, or mini lemon cheesecake. When you want another single serving muffin, see our single serve maple muffin or small batch banana muffins.
Ingredient Notes
If you have any ingredients leftover from this lemon blueberry muffin recipe, check out our Leftover Ingredients Recipe Finder.
Salted butter: Melted salted butter brings richness to the muffin. Melting it also means you can stir everything together by hand without a mixer. If you have unsalted butter, add a pinch more salt to balance the lemon’s brightness.
Sugar: Granulated sugar sweetens the batter and balances the tartness of the lemon juice. It also helps the top brown and holds moisture so the crumb stays soft.
Egg yolk: One large egg yolk binds the batter and adds the fat that gives the crumb its richness. Using only the yolk, not a whole egg, keeps the liquid in check for a muffin this small. A whole egg would make the crumb heavy and damp, especially with the lemon juice in the mix. Save the egg white for a recipe like our mini pavlova or any of our egg white recipes.
Milk: Milk loosens the batter and adds moisture. The amount is balanced with the lemon juice so the batter has the right consistency. Any milk works, whether whole, low-fat, or a non-dairy option like almond or oat milk.
Lemon juice: Fresh lemon juice gives the muffin its tart flavor. Use extra lemon juice in our lemon posset for one.
Lemon zest: Lemon zest carries the most concentrated lemon flavor of any part of the fruit. The yellow peel releases its flavor into the batter as it bakes, giving the muffin its bright lemon character. Use a microplane and zest only the yellow part. The white pith underneath is bitter.
Vanilla extract: Vanilla adds a soft background note to round out the lemon and blueberry flavors.
All-purpose flour: Flour gives the muffin its structure. As it mixes with the wet ingredients, it forms the gluten that holds the crumb together. A 1:1 gluten-free baking flour works in its place if you need it.
Baking powder: Baking powder is the only leavener in this recipe, so it does all the lifting. It releases gas as the batter heats, creating the air pockets that give the muffin its rise and soft texture.
Salt: A small amount of salt sharpens the flavors and balances both the sugar’s sweetness and the lemon’s tartness, so the muffin tastes bright rather than flat.
Blueberries: Fresh blueberries are folded into the batter and bake into sweet, soft pockets that contrast with the lemon’s tartness. Frozen blueberries work too; thaw and drain them first so the extra liquid doesn’t water down the batter.
Lemon glaze: The glaze is just powdered sugar whisked with lemon juice into a thin drizzle. It’s added once the muffin is cool so it sets on top instead of melting into the crumb.
Recipe Variations
Here are a few simple ways to change up this lemon blueberry muffin for one.
Small batch lemon blueberry muffins: To make 2 muffins, double all the ingredients and divide the batter between two 10-ounce ramekins. Two ramekins bake in about the same time as one. You can also bake the doubled batter in a single 5×5-inch baking dish; start checking a few minutes early since a shallower dish bakes faster. Double the glaze ingredients to drizzle over both muffins.
Streusel topping: For a sweet, crumbly top, mix 2 tablespoons all-purpose flour, 2 tablespoons brown sugar, 1/4 teaspoon ground cinnamon, and 1 tablespoon softened butter together with your fingers or a fork until crumbly, then scatter it over the batter before baking. Skip the lemon glaze, or use both if you want extra sweetness on top. Or scatter 1 tablespoon of granulated sugar mixed with a pinch of lemon zest over the batter before baking for a simpler crunchy finish.
Raspberry lemon: Swap the blueberries for fresh raspberries using the same amount. Fold them in gently since raspberries are more delicate than blueberries and will break apart easily.
Lemon white chocolate chip: Fold 2 tablespoons of white chocolate chips into the batter along with the blueberries. The sweetness of the chips balances the lemon’s tartness.
How To Make This Single Lemon Blueberry Muffin
Follow the steps below to make this lemon blueberry muffin recipe. See the recipe card for full ingredient amounts and exact measurements.
- In a small bowl, whisk together the flour, baking powder, and salt.
- In a medium bowl, stir together the melted butter and sugar. Add the egg yolk and whisk until smooth, then whisk in the lemon zest, vanilla, milk, and lemon juice.
- Add the dry ingredients to the wet and stir gently until no streaks of flour remain, then fold in the blueberries with a spatula.
- Spoon the batter into a greased 10-ounce ramekin and set the ramekin on a small baking sheet.
- Bake at 400°F (200°C) for 15 minutes, until the top is golden and a toothpick inserted in the center comes out clean.
- Let the muffin cool, then whisk the powdered sugar and lemon juice together for the glaze and drizzle it over the top.
Expert Tips
- Don’t Overmix: Mix just until combined. A few lumps are fine – overmixing can make the muffin tough.
- Fold in Blueberries Gently: This helps keep them from bursting in the batter.
- Grease the Ramekin: Coat your 10-ounce ramekin well to prevent sticking.
- Use a Baking Sheet: Place the ramekin on a small baking sheet to catch any drips and make it easier to remove from the oven.
