Prep notes
Shred the zucchini on the large holes of a box grater or pulse it briefly in a food processor. If the zucchini is very watery, gently press it in a clean kitchen towel to remove excess liquid; you don’t need dry zucchini—just avoid puddles that could dilute the batter. Measure all ingredients before starting to keep the process smooth. Preheat your oven so it’s ready when your batter is mixed.
Step-by-step instructions
- Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or lightly grease the cups so the muffins release easily.
- In a medium bowl, whisk together the dry ingredients: 1 cup Whole Wheat Pastry Flour, 1/2 cup EAS Complete Protein Vanilla, 1/2 teaspoon nutmeg, 1 teaspoon cinnamon, 1/8 teaspoon kosher salt, and 1 teaspoon baking soda. Ensure the baking soda and spices are evenly distributed so the flavor and lift are consistent across the batter.
- In a large mixing bowl, combine the wet ingredients: 3 tablespoons butter unsalted, melted and cooled, 3 ounces Greek yogurt plain fat-free, 1 large egg, 2 teaspoons vanilla, and 3 ounces honey. Whisk until the mixture is smooth and glossy. The cooled melted butter should be well incorporated so it doesn’t cook the egg.
- Add the shredded zucchini to the wet mixture. Stir to fold the zucchini through the wet ingredients until evenly distributed. This step keeps the zucchini from clumping and ensures it hydrates with the wet ingredients before the dry mix is added.
- Pour the dry ingredient mixture into the bowl with the wet ingredients. Gently fold the batter using a spatula until just combined. Avoid over-mixing; a few streaks of flour are fine. Overworking the batter can make muffins tough instead of tender.
- If using walnuts, fold in 1/2 cup walnuts now, reserving a few for sprinkling on top if you like a decorative crunch. Again, fold gently until the nuts are evenly distributed throughout the batter.
- Divide the batter evenly among the prepared muffin cups. Fill each cup about three-quarters full to allow room for even rise. If you reserved walnut pieces, place one or two on top of each muffin for texture and appearance.
- Bake in the preheated 350°F (175°C) oven for 18–22 minutes, or until a toothpick inserted into the center of a muffin comes out with a few moist crumbs but not raw batter. Ovens vary, so start checking at 18 minutes.
- Remove the muffins from the oven and let them cool in the tin for 5–7 minutes. Then transfer them to a cooling rack to finish cooling. This prevents sogginess and keeps the bottoms from steaming in the hot tin.
- Store cooled muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. They also freeze well: wrap individually and place in a freezer-safe container for up to 3 months. Thaw at room temperature or warm briefly in the microwave before serving.
Troubleshooting & tips
- If your batter seems too thick, it’s okay—zucchini holds moisture and the protein powder can absorb extra liquid. Avoid adding more yogurt or butter unless the batter is unworkably stiff.
- To shred zucchini quickly, use the large holes on a box grater. If zucchini is especially watery, pat it with a towel, but don’t squeeze it dry—some moisture is needed for tender muffins.
- For uniform muffins, use an ice cream scoop to portion batter into the tin. This creates consistent sizes and helps them bake evenly.
- Honey can brown quickly. If your muffin tops are deeply browning before the centers are done, tent the pan loosely with foil for the remaining bake time.
- Toasting the walnuts before folding them in intensifies their flavor: spread them on a baking sheet and toast at 350°F (175°C) for 5–7 minutes, watching closely to prevent burning. Cool before adding to the batter.
Flavor variations
- Swap some or all of the walnuts for pecans or sunflower seeds if you prefer different textures or need a nut-free option (use 1/2 cup seeds if skipping nuts).
- Mix in 1/4 cup raisins or dried cranberries for a chewy burst of sweetness.
- Stir in 1/3 cup dark chocolate chips for an indulgent twist, but reduce honey slightly if you want less sweetness.
- For a nuttier muffin, replace the vanilla protein powder with an unflavored version and add 1/2 teaspoon almond extract along with the vanilla.
Serving suggestions
- Warm a muffin slightly and spread with a thin layer of nut butter for added protein and richness.
- Pair a muffin with a cup of coffee or tea for a satisfying morning combo.
- Serve alongside a bowl of cottage cheese or a smoothie for a balanced breakfast that keeps you full through busy mornings.

Make-ahead and storage
These muffins are ideal for batching. After cooling completely, store them in an airtight container for a couple of days at room temperature.
