Ingredients Notes
Full recipe and ingredients are in the recipe card below. Feel free to scroll through this section to view certain key ingredients we’re using!
- Blueberries – Make sure to use fresh, and not frozen. Frozen berries hold a lot more liquid, therefore making the batter runnier and affecting the entire bake.
- Buttermilk – Buttermilk is an important ingredient in these muffins. The acid in the buttermilk works with the leavening agents to give a fluffier crumb and more of a rise. To make buttermilk, stir 1 cup of milk with 1 tbsp of lemon juice or vinegar. Allow to sit on your counter for at least 10 minutes before using.
- Flour – All-purpose flour is used in this recipe.
- Lemon – Both lemon zest and lemon juice are used in this recipe.
- Eggs – Make sure they’re at room temperature before beginning.
- Oil – I used a flavourless oil.
Step by step instructions
Here is how to make and bake these Lemon Blueberry Streusel Muffins. You will need a 12 muffin tin, muffin liners, 3 mixing bowls, a spatula, and a whisk.
Step 1 – Prep. Line the muffin tin with 12 liners and set aside. If you need a recommendation, this is my favourite tin.
Step 2 – Make the streusel. Add the flour, sugar, and cold butter into a medium-sized bowl. Using your hands or a fork, mix this until crumbly and combined. Set into the refridgerator while you make the muffin batter.
Step 3 – Mix dry ingredients. Into another medium-sized bowl, add in your dry ingredients; flour, baking soda, baking powder, cornstarch, and salt. Stir together and set aside.
Step 4 – Mix lemon zest and white sugar. In a large bowl, add white sugar and lemon zest. Using your fingers, combine them to release all of the lemon oils and fragrances. Do this for 1-2 minutes.
Step 5 – Add wet ingredients. Into the large bowl with the lemon sugar mixture, add the rest of the wet ingredients; oil, butter, eggs, lemon juice, vanilla, and buttermilk. Whisk until well combined.
Step 6 – Add in dry ingredients. Pour the dry ingredients into the wet and using a spatula, gently fold to create a soft muffin batter.
Step 7 – Add blueberries. Gently toss the blueberries in 1-2 tsps of flour before adding them into the mixing bowl. This will help absorb any liquid they may have from washing and prevent them from sinking to the bottom. Then add into the bowl and mix in a few times.
Step 8 – Scoop. Evenly divide the batter between 12 liners, they should be almost or all the way full. Using a cookie scooper helps big time to minimize the mess. Sprinkle streusel and extra berries on top.
Step 9 – Bake. Bake the muffins at 425°F for 5 minutes, then turn down to 350°F and bake for an additional 17-22 minutes. The muffins are ready when a toothpick inserted comes out clean.
These muffins stay are best served fresh or the next day. They stay good on the counter covered at room temperature for a few days, or in the refrigerator 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.
- If you don't want to make the streusel, add some extra white sugar on top before baking! This will give you a delicious crisp sugary muffin top we all love.
- Use fresh, not frozen. Make sure to use fresh blueberries!
FAQ
Do I have to add blueberries?
No! Feel free to leave them out or add another berry in like raspberries, strawberries, or blackberries.
I have extra streusel leftover! What do I do?
Streusel freezes very well. Take any leftovers you may have and place it in a ziplock freezer-safe bag and freeze it! Next time you’re baking, you’ve got it right on hand. You also don’t need to thaw it out before using.
Why do you do 2 temperatures?
The first temperature is a short-term high temperature. The goal here is that the heat causes the muffins to rise quickly and create a tall and beautiful muffin dome.
Then, once you lower it down, it continues to bake inside.
