Step 1

Preheat oven to 400 degrees Fahrenheit.  Use one regular size muffin pan (12 muffins).  Line muffin cups with muffin liners.

Step 2

In a medium bowl, mix together flour, white sugar, salt, and baking powder.

Step 3

In a separate large bowl, add vegetable oil, 2 eggs, and Greek yogurt and whisk to combine.

Step 4

Add flour mixture from step 2 to the liquid mixture in step 3 and mix just enough to combine.

Step 5

In a separate medium size bowl (the one you used in step 2), combine berries with 2 tablespoons of flour. This is supposed to prevent berries from clumping together and sinking. Fold in the berries into the batter.

Step 6

To make the streusel topping, combine brown sugar, flour, cinnamon, and butter in a small bowl. Mix until you have crumb-like mixture.

Step 7

Fill muffin cups with the muffin batter about 3/4 full. Sprinkle the streusel topping over muffins.

Step 8

Bake for about 20 minutes in the oven.
