# What You'll Need:
→ Dry Ingredients
01 - 2 cups all-purpose flour
02 - 1 teaspoon baking soda
03 - 1/2 teaspoon fine salt
→ Wet Ingredients
04 - 3 medium ripe bananas, mashed
05 - 2/3 cup granulated sugar
06 - 1/2 cup vegetable oil (or 1/2 cup melted unsalted butter)
07 - 2 large eggs
08 - 1 teaspoon pure vanilla extract
→ Matcha Swirl
09 - 1 1/2 tablespoons culinary-grade matcha powder
10 - 2 tablespoons milk (dairy or non-dairy)
→ Optional Add-ins
11 - 1/2 cup chopped walnuts or dark chocolate chips (optional)
# Directions:
01 - Preheat the oven to 350°F. Grease a 9x5-inch loaf pan or line it with parchment paper; set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda and salt until evenly distributed.
03 - In a large bowl, whisk the mashed bananas with granulated sugar, vegetable oil (or melted butter), eggs and vanilla until smooth and homogenous.
04 - Fold the dry mixture into the wet mixture with a rubber spatula just until no streaks of flour remain; avoid overmixing to preserve tenderness.
05 - Spoon approximately 1 cup of the combined banana batter into a small bowl. Stir in the matcha powder and milk until the batter is uniformly green and smooth.
06 - Spoon half of the plain banana batter into the prepared pan, dollop half of the matcha batter on top, then repeat with the remaining plain and matcha batters to build layers.
07 - Use a butter knife or a skewer to gently swirl the two batters to create a marbled pattern; work briefly to avoid blending the batters together.
08 - Bake on the middle rack for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
09 - Allow the loaf to cool in the pan for 10 minutes, then transfer to a wire rack and cool completely before slicing to ensure clean slices.
