Description

Bakery-style Healthy Double Chocolate Zucchini Muffins that are moist, rich, and secretly healthy. Each muffin has about 11g of protein and only 185 calories, making them a guilt-free treat for breakfast, snacks, or dessert.


Ingredients

1 egg, room temperature

100 g yogurt, vanilla or plain, room temperature

200 ml light milk + 1/2 tsp vinegar or lemon juice (to make buttermilk)

1 tsp vanilla extract

1 medium zucchini, grated and excess liquid squeezed out

100 g granulated sweetener (or sugar/monkfruit/brown sugar)

130 g all-purpose flour (or oat flour substitute)

20 g cocoa powder

60 g chocolate protein powder (plant-based or whey)

1 1/2 tsp baking powder

1/4 tsp baking soda

1/4 tsp salt

100 g chocolate chips/chunks (reserve some for topping)


Instructions

  1. Grate the zucchini and squeeze out as much liquid as possible using a clean towel. Set aside.
  2. In a large bowl, whisk the egg, yogurt, and milk until smooth. Add zucchini and sweetener and mix well.
  3. Stir in protein powder, flour, cocoa powder, baking powder, baking soda, and salt. Mix gently until just combined.
  4. Fold in the chocolate chips/chunks, reserving some for topping.
  5. Optional: Cover and refrigerate the batter for 30 minutes (or overnight) for a thicker texture and better rise.
  6. Preheat oven to 220°C (425°F). Line a muffin tray with 8–10 liners.
  7. Divide the batter evenly, filling each cup about ¾ full. Top with reserved chocolate chunks.
  8. Bake at 220°C (425°F) for 5 minutes, then reduce heat to 180°C (350°F) and bake for 12–15 minutes, until a toothpick comes out with just a few crumbs.
  9. Let muffins cool in the pan for 5–10 minutes before transferring to a wire rack.

Notes

Chilling the batter helps with rise and texture, but can be skipped.

For gluten-free option, use oat flour.

Add 1/2 tsp espresso powder for deeper chocolate flavor.

Swap chocolate chips with cacao nibs, peanut butter chips, or white chocolate chips for variations.

Muffins freeze well for up to 3 months.
