Moist High Protein Banana Bread Recipe

Bake the Moist High Protein Banana Bread Recipe for a moist, protein-rich loaf with creamy peanut butter-cream cheese frosting.

Ingredients

• 2 1/4 cups oat flour (I always use King Arthur for a consistent fine grind)
• 3/4 cup peanut butter protein powder
• 3/4 cup vanilla protein powder
• 1 tsp baking soda
• 1 tsp baking powder
• 1/2 tsp salt
• 2 1/2 tsp cinnamon
• 1/4 tsp nutmeg
• 6 bananas (very ripe with brown spots for natural sweetness)
• 1/2 cup yogurt (I prefer Fage 5% Greek yogurt for a richer crumb)
• 1/2 cup coconut oil
• 1/2 cup maple syrup
• 1 tsp vanilla essence
• 1/2 tbsp vanilla paste (I like Nielsen-Massey to provide those beautiful bean flecks)
• 6 eggs
• 1/2 cup carrots (finely shredded using the smallest holes on a box grater)
• 1/2 tsp ginger
• 1/4 tsp nutmeg
• 1/3 cup pecans
• 8 oz cream cheese (room temperature, about 70°F, to prevent lumps)
• 1/4 cup peanut butter (I use Jif creamy for the smoothest texture)
• 3 tbsp maple syrup
• 1/2 tsp vanilla essence
• 1/2 tbsp vanilla paste
• 1/8 tsp sea salt

Instructions

Step 1: Preheat and Prepare the Pan

Preheat the oven to 350°F and grease a 9×5-inch loaf pan thoroughly with butter or cooking spray so the loaf releases cleanly. Line a small sheet of parchment beside the pan if you prefer an easy lift-out; set the prepared pan on the painted pine wood surface while you assemble the batter.

Step 2: Whisk the Dry Mixture

In a large bowl whisk together the oat flour, peanut butter protein powder, vanilla protein powder, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger until the leavening and spices are evenly distributed and there are no lumps in the flour mixture.

Step 3: Mash Bananas and Soften the Cream Cheese

Thoroughly mash the very ripe bananas with a fork until mostly smooth with a few small lumps remaining. As the bananas rest briefly, place the cream cheese on the counter to come to room temperature (about 70°F) so it will integrate seamlessly later when you make the frosting.

Step 4: Combine the Wet Ingredients

Stir the yogurt, melted coconut oil, maple syrup, vanilla essence, vanilla paste (with visible bean flecks), and eggs into the mashed bananas until uniformly mixed and slightly glossy.

Step 5: Fold Wet into Dry and Add Mix-Ins

Pour the wet mixture into the dry mixture and fold gently until just combined — avoid overmixing to keep the crumb tender. Fold in the finely shredded carrots and chopped pecans for the carrot variation, distributing them evenly, then transfer the batter into the greased 9×5-inch loaf pan and smooth the top with a spatula.

Step 6: Bake and Cool

Bake the loaf for about 48–50 minutes until a toothpick inserted into the center comes out with a few moist crumbs. Let the bread cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely before frosting.

Step 7: Beat the Cream Cheese Base

Once the cream cheese has reached room temperature, beat it with an electric mixer for about a minute until silky and lump-free, the perfect base for a light, whipped frosting.

Step 8: Add the Peanut Butter and Sweeteners

Add the peanut butter and beat until smooth, then incorporate the maple syrup, vanilla essence, vanilla paste, and a pinch of sea salt. Beat the frosting until it becomes light, slightly airy, and evenly flavored.

Step 9: Frost, Slice, and Serve

When the loaf is completely cooled, spread the frosting evenly across the top, creating a gentle swirl and leaving small visible vanilla bean flecks. Dust lightly with cinnamon or nutmeg for rustic charm, slice into thick pieces that reveal the dense, moist crumb studded with banana, carrot and pecan, and serve at room temperature or chilled as desired.

Step 10: Storage

Keep the frosted loaf covered at room temperature for up to three days, or refrigerate for longer storage. Enjoy slices with coffee or a glass of water for a balanced, protein-rich treat.

Notes

• Use very ripe, brown-spotted bananas for best sweetness and moisture.
• Soften cream cheese to room temperature to avoid lumps in the frosting.
• Measure oat flour by spooning into the cup and leveling, do not compact.
• Swap protein powders or nut butters to accommodate dietary needs or allergies.
• Freeze unfrosted loaf wrapped tightly for up to three months.
