How To Make High Protein Zucchini Bread (Quick Overview)

The steps below are just a quick overview of how to make the high protein zucchini bread. The full process in detail is located in the recipe card at the end of the post.

First, do the prep work by preheating your oven and preparing a loaf pan. (See the recipe at the end of the post for more details.)

In a mixing bowl, sift together the flour, protein powder, salt, baking powder, baking soda, and cinnamon. If you’re adding pecans or walnuts, toss those in now too. Set aside.

In another bowl, whisk together the Greek yogurt, eggs, vegetable oil, white sugar, brown sugar, and vanilla extract until smooth.

Stir in the grated zucchini until it’s fully mixed in.

Add the dry ingredients to the wet mixture and gently stir until just combined, being careful not to overmix.

Pour into the prepared loaf pan.

If possible, place the pan immediately in the oven. If you don’t, the batter will start to settle a bit – like you see in my photos! It still tastes great, but won’t be as pretty if you don’t bake it immediately.

Bake, covering with foil after about 15 minutes to keep the top from burning.

When you remove it from the oven, let it cool in the loaf pan for an hour, then remove it from the loaf pan to finish cooling completely.

Slice, serve, and enjoy!

How to Store High-Protein Zucchini Bread in the Refrigerator

Because zucchini bread is so moist, I don’t recommend keeping it at room temperature for more than a day (or never, if possible).

It’s best stored in the fridge. Once it has cooled completely, you can store it in the fridge in plastic wrap, an airtight container, or a resealable zip-top bag. It can be stored whole or as individual slices.

Stored in the fridge, it will stay flavorful and fresh for up to a week. When you’re ready to enjoy it, you can eat it cold or pop it in the microwave for a few seconds.

How to Freeze High Protein Zucchini Bread in the Freezer

This bread can be frozen too, for up to three months. It’s best stored in freezer-safe zip-top bags or airtight containers

When you’re ready to eat it, let it thaw in the fridge and then dig in. Freezing adds in more moisture, so your bread will be extra-moist and delicious!
