Step 1: Preheat and Prepare the Pan
Preheat the oven to 350°F (175°C).

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
Step 3: Combine Wet Ingredients
In a large bowl, mash bananas until smooth.
Add granulated sugar, brown sugar, peanut butter, melted coconut oil, vanilla extract, and almond milk.
Mix well until fully combined.
Step 4: Fold in the Dry Mixture
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chopped peanuts, if using.
Step 5: Bake the Banana Bread
Pour the batter into the prepared loaf pan.
Bake for 50 minutes or until a toothpick inserted in the center comes out clean.
Step 6: Cool the Bread
Remove from the oven and cool in the pan for 10 minutes.
Transfer to a wire rack to cool completely.
Step 7: Prepare the Latte Glaze
In a small bowl, whisk powdered sugar, brewed espresso, and vanilla extract until smooth.
Drizzle the glaze over the cooled banana bread.
