Step by step instructions
Here is how to make and bake these Olive Oil Muffins. You will need a 12 muffin tin, muffin liners, 3 large mixing bowls, a spatula, and a whisk.
Step 1 – Prep. Line the muffin liners with 12 liners and set aside. If you need a recommendation, this is my favourite tin.
Step 2 – Mix dry ingredients. In a small bowl, whisk together flour, salt, cornstarch, baking powder, and baking soda. Set aside.
Step 3 - Mix lemon zest and white sugar. In a large bowl, add the lemon zest and white sugar. Using your fingers, rub them together for 1 minute. This will release the lemon zest aromas and taste.


Step 4 - Add in oil and butter. Into the same bowl, add the olive oil and melted butter. Whisk until well combined, about 2-3 minutes.


Step 5 - Add eggs and vanilla. Add in the eggs and vanilla and continue whisking until combined and smooth.


Step 6 - Add in sour cream and lemon juice. Mix in the sour cream and lemon juice until well incorporated.


Step 7 - Add in dry ingredients. Add the dry into the wet and using a spatula, gently fold until just combined and no dry streaks appear.


Step 8 - Scoop and bake. Scoop the muffins into your liners filling them up almost to the top.


Step 9 - Bake. Bake the muffins for 20-25 minutes or until a toothpick inserted comes out clean.
These muffins are so delicious! They stay good on your counter for 2 days, and in the fridge in an airtight container for up to 1 week.

Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale. I cannot emphasize this enough! It is the most accurate way of measuring your ingredients in the kitchen. This is one of my favourites.
- Mixing the dry ingredients in a separate bowl is very important. This way you evenly distribute the levening agents before adding it into the wet ingredients, so all muffins rise evenly.
- Do not over-mix! A big reason muffins don’t rise or turn out tough is because the batter is over-mixed. Once you see no flour streaks, stop mixing.
FAQ
Do I have to add butter?
No! You can use oil instead. I like adding butter in for some more flavour.
Do I have to add lemon juice and lemon zest?
Yes! These muffins don't have a lot of flavour, so adding these is crucial.
