What You Will Need
For the Cake
- One 11×7 Inch Glass Baking Dish – To bake your banana bars in.
- Flour – I used 1 1/2 cups of all-purpose (since that is all I had on hand!), but oat flour works really awesome as well and it probably my preferred choice!
- Vanilla Protein Powder – For some vanilla flavor and protein! My personal favorite is by the brand Prozis (either the zero diet whey vanilla or the natural vanilla whey isolate). You can actually use the code “KATIE10″ for 10% off at Prozis!
- Granulated Sugar Substitute– I used 1/2 cup of Swerve, which is my go-to when it comes to sugar alternatives. Swerve is a zero-calorie, low-glycemic sweetener that measures cup-for-cup to sugar. It’s completely save and natural, with no artificial ingredients, preservatives or flavors. It is safe for diabetics and Keto approved. You can purchase Swerve off of Amazon here.
- Salt – 1/2 teaspoon, for flavor.
- Baking Soda – 1 teaspoon, to make the cake rise
- Cinnamon & nutmeg – 1 teaspoon of cinnamon & 1/2 teaspoon of nutmeg, for flavor
- Eggs– This is what helps makes the cake super fluffy and contributes to the protein content. You will need 2 large eggs.
- Vanilla Extract – 1 teaspoon, for flavor.
- Greek Yogurt – I used 1 cup of plain non-fat Greek yogurt. This is the key ingredient to getting the most moist & fluffy cake! It also adds more protein to the banana bars!
- Bananas – The most important ingredient! You will need 3 mashed bananas.
For the Frosting
- Cream Cheese – I used 4 ounces of low fat cream cheese to keep the fat & calories low. It’s easiest to work with softened cream cheese.
- Unsweetened Almond Milk– I used 2 tablespoons of a vanilla flavored one, but feel free to do a different flavor or even a different type of milk.
- Vanilla Extract – For flavor.
- Powdered Sugar Substitute – I used Swerve again for this! I used 2 tablespoons.
- Vanilla Protein Powder – I used 45 grams of Prozis Zero Vanilla Whey Protein.
How To Make It
- Preheat your oven to 350°F. Spray an 11×7 inch baking dish with nonstick spray.
- In a large mixing bowl, beat the egg whites, cream of tartar, and vanilla extract with a hand mixer until stiff peaks form.
- Using a rubber spatula, fold in your protein powder and stevia. Be sure to do this very gently! You do not want your egg whites to deflate too much.
- Place your cake batter in your spring foam pan and bake for 20 minutes.
- Once the cake pan is cool enough to touch, place it in the fridge to completely cool it.
- In a small mixing bowl, beat the cream cheese, sweetener, pudding mix, Greek yogurt, and almond milk with a hand mixer on low until well combined.
- Take the outer part of the spring foam pan off carefully and use the bottom of it as your platter.
- Using a rubber spatula, gently frost the cake. Cover the top and all sides.
- Top with fresh strawberries if desired. Slice the angel food cake into 8 slices and enjoy!
How To Store
Store your Protein Banana Cake Bars in an airtight container in the refrigerator for up to 5 days. You can also keep them in the original baking dish and cover that with plastic wrap in your fridge.
Do You Eat These Warm or Cold?
These are honestly amazing both ways. Personally, I like to warm them up a little in the microwave, but not too much to the point where the cream cheese frosting melts!
