Ingredients

Muffins:

  • 1 cup all-purpose flour
  • 1/2 cup whole wheat flour
  • 1/2 cup brown sugar
  • 1/4 cup white sugar
  • 1 tsp baking soda
  • 1 tsp cinnamon
  • 1/2 tsp kosher salt
  • 1/2 cup olive oil
  • 1/4 cup sour cream
  • 1 large egg slightly beaten
  • 2 tsp vanilla extract
  • 1 1/2 cups zucchini shredded with as much liquid squeezed out as possible, packed
  • 1 cup blueberries fresh

Streusal Topping:

  • 3 tablespoons all-purpose flour
  • 3 tablespoons brown sugar
  • 1/2 tsp cinnamon
  • 3 tablespoons unsalted butter cold, cut into small pieces
  • 1/2 cup pecans crushed

Instructions

  • Preheat oven to 350 degrees F. Grease 12 muffin cups or line with paper liners.
  • Whisk together flours, sugars, baking soda, cinnamon, and salt together in a bowl. 
  • Whisk olive oil, sour cream, egg, and vanilla extract in a separate bowl until smooth.
  • Stir wet ingredients into flour mixture until batter is just moistened. Batter will be very thick. Stir in shredded zucchini and mix well. Gently fold in blueberries. 
  • To make the streusel, combine flour, sugar, butter, cinnamon, and pecan pieces. Use a fork or a pastry blender to evenly distribute butter chunks. 
  • Fill prepared muffin cups 2/3 full with batter. A cookie scoop works great for this task. Top with equal amounts of streusel.
  • Bake in preheated oven until a toothpick inserted into the center of a muffin comes out clean, 20 to 25 minutes for regular sized muffins or 25-30 minutes for jumbo ovens (cooking times will vary).
