Step by step instructions
Here is how to make and bake these Blueberry Orange Streusel Muffins. You will need a 12 muffin tin, muffin liners, 3 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 buttery sugar streusel. Place in the fridge to chill.

Step 2 - Mix dry ingredients. Add flour, baking soda, baking powder, cornstarch, and salt. Stir to combine and set aside.
Step 3 - Combine orange zest and sugar. In a large bowl, add the orange zest and sugar and combine it with your fingers for 1-2 minutes.


Step 4- Whisk in wet ingredients. Into the same bowl, add the melted butter, oil, eggs, vanilla, buttermilk, and orange juice. Whisk well to combine.
Step 5 - Add in dry ingredients. Mix the dry and wet ingredients together until almost completely combined.


Step 6 - Mix in blueberries. Gently toss the blueberries in 1 tsp of flour before adding them into the batter, then mix them in. Don't over-mix!


Step 7 - Scoop. Divide the batter evenly between the liners, filling them to the top. Sprinkle a generous handful of streusel on top.


Step 8 - Bake. Bake the muffins at 425°F for 5 minutes, then lower the oven temperature to 375°F and continue baking for 15-20 minutes or until a toothpick inserted in the middle comes out dry.
Allow to cool, and enjoy! These blueberry orange muffins are so delicious!

FAQ
How do I store these muffins?
These muffins are best eaten fresh within the first 3 days. They stay good on the counter for up to 5 days in a display case, or in the refrigerator in a container for up to 1 week!
Why do you dust the berries in flour?
This helps soak up any water the berries might have from washing, and prevent them from sinking as they bake.
Do I have to make the streusel?
No, but I highly recommend it!
Why do you bake them at two temperatures?
The first 5 minutes at 425°F helps trigger the leavening agents to activate, causes the batter to rise fast, and creates that bakery-style muffin dome top we all love. Once lowered to 375°F, it continue to bakes evenly throughout!
Can I use frozen blueberries?
Yes! If using frozen, do not thaw them. Toss them in 1 tsp of flour, then add them directly into the bowl, mix, and bake immediately.
