Cannoli Muffins

Preheat the oven to 350 degrees F (175 degrees C). Line 18 muffin cups with paper liners.

Whisk flour, baking powder, and salt together in a large bowl.

Whisk eggs, 1/2 cup plus 2 1/2 tablespoons orange juice, 1/2 cup plus 2 tablespoons ricotta, vegetable oil, milk, sugar, orange zest, sour cream, and vinegar in a medium bowl. Make a well in the center of the flour mixture; pour in egg mixture and chocolate chips. Stir until flour is just moistened. Be sure not to overmix to avoid overly tough muffins.
