Preheat the oven to 350F. Spray a loaf pan with oil.

Add mashed bananas, peanut butter, baking powder, and eggs to a large bowl. Combine all of the ingredients to form a batter.

In a small bowl, combine matcha powder with cold water.

Transfer 1/3 of the batter into another smaller bowl and set it aside.

Now, add the matcha mixture into the original bowl and combine until the batter turns green.

Pour the green batter into the loaf pan, then cover with 1/3 of the batter that we’ve set aside.

Level out with a spoon and top up with chopped pecans.

Bake in the oven for 50 minutes. If you notice that the top of the bread is turning darker than it should, cover it with foil midway to prevent burning.

Let it cool down before slicing up and serving.
