What You'll Need To Make This High Protein Zucchini Bread

• Fresh zucchini. Grated and dropped right into the batter. 
• Coconut sugar, or your preferred granulated sweetener.
• Aquafaba. This is the bean liquids from a can of beans, simply open a can of chickpeas or white beans with a sieve or colander over a bowl and collect the juice. This is a great egg replacement in baking. If you need a bean recipe next, check this Chickpea Scramble recipe out!
• Olive oil. This adds the perfect depth of rich, healthy fats. 
• Key limes. You'll use both the juice and zest to add brightness to the zucchini bread.
• Whole wheat flour. I like Anitas organic, sprouted whole wheat for a nutritional boost. (Linked in recipe).
• Vital wheat gluten. This 1/2 cup measurement adds 46g of protein to the bread! It's also lower in carbs then regular whole wheat flour.
• Baking powder, baking soda, and salt. 
• Icing sugar. This is essential to take this zucchini bread from simple to extra special.

Substitutions

In place of coconut sugar, use any preferred granulated sweetener.

You can substitute the olive oil for grapeseed oil or avocado oil.

Can't find key limes? Regular limes will do for this zesty zucchini bread recipe.

Instead of whole wheat flour you can use all purpose white flour or gluten free flour for this zucchini bread recipe. However keep in mind removing the vital wheat gluten will reduce the protein.
