Muffins are one of my favorite things to bake and these moist mini lemon crumb muffins are easy to make and absolutely perfect for brunch or a picnic. If you’re a lemon lover you’ll want to try these!

The Perfect Picnic Size

These mini lemon crumb muffins make a wonderful snack, and if you ask me, they’re also perfect for packing along on a picnic.

  • Making these mini muffins doesn’t require any machine. Just a few bowls and a whisk is all you need
  • They’re perfect for freezing if you want to use them at a later stage
  • The crumb topping gives them a buttery and crunchy texture

Recipe Ingredients

Making these lemon crumble muffins works best if all ingredients are at room temperature. Make sure to double-check the exact quantities and ingredients in the recipe card below.

  • sugar –  I use a mix of regular granulated sugar in the muffins and light brown sugar in the crumb topping
  • oil – I typically use a neutral oil like sunflower oil for baking
  • lemon – the lemon flavor for these muffins comes from both a fresh lemon as well as lemon curd
  • egg – I use a large egg for this recipe
  • milk – whole milk gives the best flavor, but you can replace it with any kind of milk you prefer, including plant-based
  • butter – unsalted butter is preferred in this recipe
  • all-purpose flour – forms the base for both the muffins and is also part of the crumb topping
  • oats – I used old-fashioned rolled oats, which give a lovely texture to the topping

How To Make Mini Lemon Crumb Muffins

Making the batter for this easy recipe cannot be more straightforward. You ideally use two bowls. In the first bowl you add the dry ingredients (sugar, flour, baking powder, baking soda, salt and lemon zest). Use a spoon to mix it through.

In a second bowl you add the wet ingredients (egg, milk, oil and the lemon curd) and mix it until smooth.

​Next you simply add the wet ingredients to the dry ingredients and fold it together. You want any flour streaks to be gone, but it is totally fine if there are still a few lumps visible.

How to make the Crumb Topping

I use a small bowl to make the crumb topping. You add the butter, brown sugar, vanilla, flour, oats and a little bit of salt to the bowl. Use the tips of your fingers to rub it together until a crumbly mixture forms. Don’t overmix it, as you really want that crumbly texture.

Fill your mini muffin cups to about 3/4 with the batter and sprinkle the crumble topping over the top of each muffin,

​Bake at 400˚F/200˚C (conventional oven) for about 12 to 15 minutes or until they are lightly golden.

Allow to cool for a few minutes before transferring to a wire rack to cool down completely.

FAQ Mini Lemon Crumb Muffins

Can I make these mini lemon crumb muffins in a regular muffin pan?

Yes! This recipe can easily be made as regular-sized muffins. You’ll get about 10-12 muffins, and the baking time will increase to approximately 18–22 minutes. Keep an eye on them and check for doneness with a toothpick.

Can I use bottled lemon juice instead of lemon zest?

For the best flavor, I recommend using fresh lemon zest. The zest provides most of the bright citrus flavor in these muffins. Bottled lemon juice won’t give the same fresh, vibrant result. It will also have an effect on the texture as it introduces more moisture into the muffins.

Why are my muffins dense instead of fluffy?

Dense muffins are usually caused by overmixing the batter. Once you combine the wet and dry ingredients, stir only until the flour is no longer visible. A few lumps in the batter are completely normal.

How do I keep the crumb topping crunchy?

Store the muffins in an airtight container at room temperature rather than in the refrigerator. If the topping softens over time, you can refresh the muffins in a 300°F/150°C (conventional oven) oven for a few minutes.
