# What You'll Need:
→ Loaf Base
01 - 3 medium ripe bananas, mashed
02 - 2 large eggs
03 - 1/3 cup plain nonfat Greek yogurt
04 - 1/2 cup milk of choice
05 - 1/3 cup maple syrup or honey
06 - 1 teaspoon vanilla extract
07 - 1 1/2 cups all-purpose flour
08 - 1/2 cup vanilla or unflavored protein powder
09 - 1 teaspoon baking powder
10 - 1/2 teaspoon baking soda
11 - 1/2 teaspoon salt
12 - 1 teaspoon ground cinnamon
→ Cream Cheese Cinnamon Swirl
13 - 6 ounces cream cheese, softened
14 - 2 tablespoons plain nonfat Greek yogurt
15 - 1/4 cup granulated sugar or coconut sugar
16 - 1 teaspoon ground cinnamon
17 - 1 egg yolk
18 - 1 teaspoon vanilla extract
# How to Prepare:
01 - Preheat oven to 350°F. Line a 9x5-inch loaf pan with parchment paper and lightly grease the sides.
02 - In a large mixing bowl, whisk together mashed bananas, eggs, Greek yogurt, milk, maple syrup, and vanilla extract until smooth and well combined.
03 - In a separate bowl, combine flour, protein powder, baking powder, baking soda, salt, and ground cinnamon. Whisk to distribute leavening agents evenly.
04 - Gently fold dry ingredients into wet mixture using a spatula or wooden spoon. Mix only until just combined; do not overmix to preserve tender crumb structure.
05 - In a clean bowl, beat softened cream cheese, Greek yogurt, sugar, cinnamon, egg yolk, and vanilla extract until smooth and creamy using an electric or hand mixer.
06 - Pour half of the loaf batter into the prepared pan and spread evenly across the bottom.
07 - Spoon half of the cream cheese mixture evenly over the batter. Using a knife or skewer, gently swirl through the layers to create a marbled pattern.
08 - Spread the remaining loaf batter over the cream cheese layer, sealing the edges against the pan sides.
09 - Spoon remaining cream cheese mixture over the top layer and swirl gently with a knife to create decorative marbling throughout.
10 - Bake for 45 to 55 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs. Do not test with wet batter.
11 - Cool loaf in the pan for 10 minutes, then transfer to a wire cooling rack to cool completely before slicing.
