Cinnamon Swirl Protein Banana Bread

If you love cinnamon rolls and also have spotty bananas sitting around, this recipe's for you! I'm talking Cinnamon Swirl Protein Banana Bread with a drizzle of sugar free icing on top... yum! The swirl is way easier to make than you'd think and adds a ribbon of cinnamon sugar goodness to every bite. As always, this recipe is gluten free and dairy free as well.

Did you know? Bananas are a great source of resistant starch, a prebiotic that feeds beneficial bacteria in the colon. They also have pectin, a fiber that acts as a natural stool softener!

Protein recommendations

To add some protein, I used my fave pea protein isolate, LIV Body Lean Vegan Protein. I love that it has added probiotics, digestive enzymes, and organic superfoods. BONUS: the flavors taste amazing without any artificial sweeteners or artificial flavors! Use my code “SARAHWILKINS” for free shipping on any purchase.

I have also tested this recipe with soy isolate, and some readers have successfully swapped whey or casein. If you use whey, I would suggest substituting the waster in this recipe for additional almond butter or unsweetened applesauce. Collagen won't work since it behaves so differently than other protein powders!

Flour recommendations

I used gluten-free baking flour in this recipe, and have found you can use up to one-quarter cup less flour if using soy isolate. Feel free to substitute all-purpose flour, cassava flour (Paleo), oat flour (oats blended into flour), sorghum flour, spelt flour, or whole wheat pastry flour.

If using coconut flour, I would recommend only substituting up to one half cup regular flour for one-quarter cup of coconut flour to reduce the carbs. Using more may result in a mealy texture.

Sweetener recommendations

To sweeten this banana bread, I used this monk fruit-allulose blend that measures like sugar! Feel free to use granulated monk fruit, granulated erythritol, baking stevia, or any other sweetener that measures like sugar. If using coconut sugar or another granulated sugar, this will increase the calories, carbs, and sugar. I don’t recommend subbing honey or maple syrup without other modifications (such as omitting the water).

Other substitutions

I added almond butter for added moisture and richness, but feel free to use plain dairy-free yogurt, or unsweetened applesauce for a lower fat option. You can also use two to three tablespoons of coconut oil or vegan butter.

You can also sub two whole eggs for the half a cup of egg whites. If you can't have eggs, you can try flax eggs to keep this protein banana bread vegan. Or, try a vegan egg replacer

Cinnamon swirl

For the cinnamon swirl, I combined a brown sugar sweetener with ground cinnamon and vegan butter (coconut oil would work too).

These Mediterranean Turkey Stuffed Peppers are high on the flavor charts and very filling for the calories. These peppers will not only satisfy your tastebuds, but your hunger, too! I love the combination of seasoned ground turkey, lemon parsley quinoa, and goat cheese. It’s one of those things I can eat all week and not get sick of (perfect for meal prep). The kids gobbled these too, believe it or not! Make these vegan using spiced chickpeas and vegan mozzarella.
