Ingredients

Scale
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup unsweetened cocoa powder
  • 1 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1 1/2 cups grated zucchini (about 2 medium zucchini, squeezed dry)
  • 1/2 cup milk (dairy or non-dairy)
  • 1/2 cup semi-sweet chocolate chips, plus more for topping

Instructions

  1. Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large bowl, whisk together the flour, baking soda, baking powder, salt, and cocoa powder. Set this dry mixture aside.
  3. In a separate medium bowl, whisk together the granulated sugar, brown sugar, eggs, vegetable oil, vanilla extract, and cinnamon until combined.
  4. Add the wet ingredients to the dry ingredients. Mix on low speed or by hand until just combined. Do not overmix.
  5. Gently fold in the grated, squeezed zucchini and the 1/2 cup of chocolate chips using a spatula.
  6. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full. Sprinkle extra chocolate chips on top of each muffin.
  7. Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean or with moist crumbs attached.
  8. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Squeeze excess moisture from the grated zucchini using a clean kitchen towel or paper towels. This step is important for moist, not soggy, muffins.
  • For a richer flavor, substitute 1/4 cup of the oil with melted butter.
  • If you are interested in structured eating, these muffins fit well into a general meal planning approach, though they are not specifically designed for a keto meal plan delivery.
  • These freeze well for up to three months. Cool completely, then store in an airtight container or freezer bag.
