Step‑by‑Step Instructions for Protein Banana Bread – Moist, Healthy Naturally Sweetened
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that your Protein Banana Bread bakes evenly and achieves that perfect golden-brown crust. While the oven heats up, gather your ingredients and prepare your workspace for an efficient baking session.
Step 2: Prepare the Pan
Take a standard loaf pan and grease it with a little coconut oil or butter, or line it with parchment paper for easy removal. This step is crucial to prevent the banana bread from sticking, ensuring that each slice retains its lovely shape when it’s time to serve.
Step 3: Mash Bananas
In a large mixing bowl, mash the very ripe bananas using a fork or a potato masher until smooth. Aim for a consistency without large lumps, as this will create a moist texture in your Protein Banana Bread. The riper the bananas, the sweeter and more flavorful your bread will be!
Step 4: Combine Wet Ingredients
Add the eggs, melted coconut oil (or butter), natural sweetener, and vanilla extract to the mashed bananas. Mix thoroughly until all the wet ingredients are well combined. This mixture will add moisture and flavor, making the banana bread irresistibly delicious and nutritious.
Step 5: Mix Dry Ingredients
In a separate bowl, combine the oat flour, protein powder, baking powder, baking soda, and optional cinnamon. Whisk these dry ingredients together to ensure an even distribution of the leavening agents, which are essential for giving your Protein Banana Bread its delightful rise.
Step 6: Combine Mixtures
Slowly add the dry ingredient mixture into the wet mixture, stirring gently until just combined. Be careful not to overmix the batter; a few lumps are perfectly fine. This way, your Protein Banana Bread will come out tender and moist, just as it should be.
Step 7: Bake the Bread
Pour the batter into the prepared loaf pan, smoothing the top with a spatula for an even bake. Place the pan in the preheated oven and bake for 35-40 minutes. Keep an eye on it, and perform a toothpick test around the 35-minute mark; it should come out clean when the bread is done.
Step 8: Cool the Bread
Once baked, remove the Protein Banana Bread from the oven and let it cool in the pan for about 10 minutes. This resting period allows it to set properly before transferring. After that, gently turn it out onto a wire rack to cool completely, letting those lovely flavors develop even further.

How to Store and Freeze Protein Banana Bread
Room Temperature: Store the Protein Banana Bread in an airtight container at room temperature for up to 3 days. This keeps it fresh and moist, perfect for daily snacks!
Fridge: If you'd like to extend its shelf life, refrigerate it in an airtight container for up to a week. Just remember, it may dry out slightly, so toast it before enjoying.
Freezer: For longer storage, freeze slices of Protein Banana Bread wrapped in plastic wrap and then placed in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before enjoying!
Reheating: To warm up, simply pop a slice in the microwave for about 15-20 seconds or enjoy it toasted for a crispy crust.
