When looking for a tasty snack to satisfy and satiate, there is nothing better than a healthy banana bread with protein. Get ready to be surprised by how simple making protein banana bread at home really is.

First, do you know what is usually missing from a banana bread? Protein! But by adding a scoop of the right type of protein powder, you can take this recipe to the next level. This gluten-free protein banana bread is a recipe that everyone (even gluten eaters!) will enjoy.

This protein banana bread recipe keeps all the best parts about banana bread while adding a protein punch — 10 grams per slice. We’ll also use almond flour, a lower-carb alternative to all-purpose white flour.

Incorporating super-ripe bananas makes this protein powder bread sweet, but we’ll add maple syrup to make sure your sweet tooth is satisfied. Instead of butter, we’ll get that same silky texture with coconut milk. Now this is a protein-packed banana bread you can indulge in!

Best protein banana bread ingredients

• Eggs: They're key for a quality banana bread because they contribute to its quality texture along with providing healthy fats. They are a great source of several important vitamins and minerals, plus one of the best high-protein foods available. The specific amount can vary based on several different factors, including the size of the egg, but each egg typically contains between five to eight grams of protein.

• Bananas: Low in fat and providing a quick energy boost, they’re also full of potassium and fiber. In fact, just one banana contains about 10 percent of your daily recommended amount. Eating enough fiber keeps your digestive system running smoothly and helps you feel full longer.

• Almond flour: Loaded with nutrition, unlike nutritionally bankrupt white flour, almond flour is low in saturated fatty acids and rich in unsaturated fatty acids. Plus it contains filling fiber, unique and protective phytosterol antioxidants as well as plant protein.

• Coconut milk: Not just tasty and nutritious, it contains a beneficial fat called lauric acid. Lauric acid is a medium-chain fatty acid that’s easily absorbed and used by the body for energy.

• Maple syrup: It's a perfect natural sweetener. Compared to refined (or “table”) cane sugar that offers absolutely no nutrients, maple syrup contains some important antioxidants and minerals, such as zinc and manganese. It also doesn't affect blood sugar as much as sugar.

• Cinnamon: This super spice raises the flavor up another notch, plus it's higher in protective antioxidant levels than any other spice. Cinnamon also boasts a wide range of other health benefits.

• Protein powder: There are two great protein powder options for this high-protein banana bread — Ancient Nutrition's Bone Broth Protein Vanilla or Whey Protein Vanilla Bean. The Bone Broth Protein is a nourishing, concentrated bone broth that is three times as potent as homemade broth and makes it easy to get healthy gut, joint and skin support. Ancient Nutrition's Whey Protein contains grass-fed whey protein concentrate, regenerative A2/A2 milk protein (making it easier to digest) and eggshell membrane collagen. It can help you stay active, get stronger and recover faster every day. Both are also very workable protein powders for recipes like protein banana bread.

How to make protein banana bread

Fortunately, protein banana bread is one of the easier baked goods to make, and most of the prep work takes just a few minutes. Start by preheating the oven to 350 F and greasing a loaf pan with coconut oil or butter.

In a large mixing bowl, add the banana and mash it thoroughly with a fork or potato masher. For the best flavor and natural sweetness, use very ripe bananas with plenty of brown spots on the peel. A few small banana pieces are fine, but aim for a mostly smooth consistency so the banana distributes evenly throughout the bread.

Next, add the eggs, maple syrup, coconut milk and vanilla extract to the mashed banana. Whisk everything together until the ingredients are well combined and the mixture is relatively smooth.

In a separate bowl, combine the dry ingredients: baking powder, baking soda, almond flour, sea salt and cinnamon. Add your protein powder — either Bone Broth Protein Vanilla or Whey Protein Vanilla — and stir until evenly incorporated. While almond meal can work in a pinch, finely ground blanched almond flour is preferable because it produces a lighter, more bread-like texture. (You can also go with a gluten-free Paleo flour.)

Gradually add the dry mixture to the wet ingredients in the larger mixing bowl. Using a whisk or wooden spoon, gently stir everything together until just combined and no obvious pockets of dry flour remain. Avoid overmixing the batter, as you only need to stir long enough to evenly incorporate the ingredients.

Use a rubber spatula or scraper to transfer the batter into the prepared loaf pan, spreading it into an even layer. If desired, you can add sliced banana, chopped walnuts or pecans to the top before baking for extra flavor and texture.

Place the loaf pan on the center rack of the oven and bake for 45–50 minutes, or until the top is set and lightly browned. To check for doneness, insert a toothpick into the center of the loaf. It should come out mostly clean rather than coated in wet batter.

Remove the banana bread from the oven and allow it to cool in the pan for several minutes. Carefully remove the loaf and transfer it to a wire rack to finish cooling. Giving the bread time to cool before slicing also helps it set and makes it easier to cut into clean slices.

Serve the protein banana bread on its own or warm a slice and top it with butter, nut butter or your favorite spread. Store leftovers in an airtight container for an easy protein-packed breakfast, snack or better-for-you treat.

Variations

A popular variation is pouring the batter into a muffin tin to make protein banana bread muffins.

Add some walnuts or pecans for some added nut protein and some crunch. Want some more fun sweetness? Add some dark chocolate (72 percent cacao) chips to the mixture at the end and stir in.

You can also add zucchini for a veggie and protein-packed banana-zucchini bread. If you cannot eat almonds, almond flour can be substituted out for coconut flour, but as it is so absorbent, it is best to mix it 1:1, with something like tapioca flour.
