Moist Zucchini Cupcakes with Greek Yogurt Frosting

These zucchini cupcakes are incredibly moist, packed with hidden veggies, and finished with a tangy Greek yogurt frosting—an easy, healthier treat for breakfast or dessert.

Zucchini Cupcakes

I have some exciting personal news: I finally have a move-in date for my new house! After signing papers months ago and waiting through final details, the closing is set for January 25th. I’m thrilled—just 15 more sleeps until I can start decorating each room. If you follow my boards, you know how much I love planning interior design. But enough about paint swatches and curtains—back to what really matters: cupcakes.

These zucchini cupcakes are a healthier twist on a classic. They use no oil or butter, rely on whole wheat flour, and include cooked quinoa for added protein and moisture. I admit I was skeptical about baking with quinoa at first, but it yields wonderfully tender cupcakes. They’re nearly fat-free, higher in protein than most muffins, and make a great grab-and-go breakfast or pre-workout snack.

Ingredients

  • 1 cup whole wheat flour
  • 1/4 cup raw sugar
  • 1/4 cup packed brown sugar
  • 1 tsp ground cinnamon
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1/4 tsp baking soda
  • 2 eggs
  • 1/4 cup almond milk
  • 1 cup cooked quinoa (see note)
  • 1 cup shredded zucchini
  • 3/4 cup unsweetened applesauce
  • 1 tsp vanilla

Greek Yogurt Frosting

  • 6 oz plain fat-free Greek yogurt
  • 2 Tbsp honey (or agave nectar)
  • 1 tsp vanilla
  • 1 tsp lemon peel (optional, for garnish)

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. Cook the quinoa: Rinse 1/3 cup uncooked quinoa under cold water. Combine with 2/3 cup water in a small saucepan. Bring to a boil, reduce heat, cover, and simmer about 15 minutes. Remove from heat and let sit covered 5 minutes. Fluff with a fork and set aside. This yields about 1 cup cooked quinoa.
  3. In a large bowl, whisk together the whole wheat flour, raw sugar, brown sugar, cinnamon, baking powder, salt, and baking soda; set aside.
  4. In another bowl, beat the eggs with almond milk. Stir in the cooked quinoa, shredded zucchini, applesauce, and vanilla until well combined.
  5. Fold the wet mixture into the dry ingredients, stirring until just combined—do not overmix.
  6. Line or spray a 12-cup muffin tin. Fill each cup about three-quarters full with batter.
  7. Bake for approximately 20 minutes, or until a toothpick inserted in the center comes out clean. Allow cupcakes to cool for about 5 minutes in the pan, then transfer to a cooling rack to cool completely before frosting.
  8. Make the frosting: In a small bowl, whisk together the Greek yogurt, honey (or agave), and vanilla until smooth. When cupcakes are cooled, spread 2 tablespoons of frosting on each cupcake. Garnish with a little lemon peel if desired. Serve immediately or chill briefly to firm the frosting.

Notes and Tips

Quinoa adds texture and protein while keeping the cupcakes moist. If you prefer a sweeter frosting, increase the honey by 1 teaspoon at a time to taste. For a dairy-free option, use a thick nondairy yogurt, but note texture and flavor will differ. These cupcakes freeze well without frosting—thaw and top with frosting when ready to serve.
