Ingredients

  1. Dry Ingredients:

    • 1 ¾ cups almond flour

    • 2 tablespoons coconut flour

    • ¾ cup erythritol or monk fruit sweetener

    • 1 teaspoon baking powder

    • Pinch of salt

    Wet Ingredients:

    • 4 large eggs, room temp

    • ¼ cup melted butter or coconut oil

    • ½ cup unsweetened almond milk

    • 1 teaspoon banana extract

    • 1 teaspoon vanilla extract

    Chocolate Swirl:

    • 2 tablespoons unsweetened cocoa powder

    • 1 tablespoon sweetener

    • 1–2 tablespoons almond milk

    Optional:

    • Sugar-free chocolate chips

    • Chopped walnuts or pecans

Instructions

  1. Preheat oven to 350°F (175°C). Grease a loaf pan and line with parchment paper.

  2. In a large bowl, mix almond flour, coconut flour, sweetener, baking powder, and salt.

  3. In another bowl, whisk eggs, melted butter or oil, almond milk, banana extract, and vanilla until smooth.

  4. Combine wet and dry ingredients. Stir until just mixed.

  5. Remove 1 cup of the batter into a small bowl. Add cocoa powder, sweetener, and almond milk to create chocolate swirl.

  6. In the loaf pan, layer half the banana batter, dollops of chocolate batter, then the rest of the banana batter. Top with more chocolate batter. Swirl lightly with a knife.

  7. Bake 45–55 minutes. Toothpick should come out mostly clean.

  8. Cool in pan 10 minutes, then transfer to wire rack.

Notes

Use high-quality banana extract for best flavor. Don’t over-swirl, or you’ll lose the marble effect. This freezes great—slice before freezing for easy grab-and-go snacks. Tastes even better the next day.
