Step by step instructions
Here is how to make and bake these Lemon Streusel Muffins. You will need a 12 muffin tin, muffin liners, 3 mixing bowls, a spatula, and a whisk.
Step 1 - Make the streusel. In a bowl, add the butter, flour, and sugar. With your fingers, combine to form a streusel. Place in the fridge to chill.

Step 2 - Mix dry ingredients. In a bowl, add the flour, cornstarch, baking soda, baking powder, and salt. Stir to combine and set aside.
Step 3 - Combine lemon zest and sugar. With your fingers, rub the lemon zest and sugar together until combined and the aroma of lemon fills the air (about a minute).
Step 4 - Whisk in wet ingredients. Add in the oil, lemon juice, eggs, vanilla, and greek yogurt. Whisk until well combined (1-2 minutes).


Step 5 - Combine together. Add the dry and wet ingredients together and with a spatula, gently mix just until a soft batter forms. Do not over-mix!
Step 6 - Scoop and bake. Scoop the muffins evenly between the liners, filling them all the way to the top. Add a handful of streusel on top of each muffin.


Bake the muffins for 22-28 minutes or until a toothpick inserted comes out clean. Allow to cool, and enjoy!

Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale - it's easy to measure wrong using just the cups.
- Don't over-mix. Mix just until a muffin batter forms and the flour streaks disappear. Over-mixing can lead to tough muffins.
- Fill the liners. Make sure they are filled to the top! That will give you that bakery-style dome that we all love.
