Step 1: Prep the Oven and Pan
Preheat the oven to 350°F (175°C). Grease and line a loaf pan with parchment paper.
Step 2: Combine Dry Ingredients
Whisk together flour, ground pistachios, baking powder, baking soda, and salt in a bowl. Set aside.
Step 3: Mix Wet Ingredients
In another bowl, beat eggs, granulated sugar, brown sugar, melted butter, and vanilla until smooth. Stir in mashed bananas and Greek yogurt.
Step 4: Incorporate the Dry Mixture
Gradually fold the dry mixture into the wet ingredients until just combined.
Step 5: Pour and Bake
Pour the batter into the prepared loaf pan. Bake for 55 minutes or until a toothpick comes out clean. Let cool completely.
Step 6: Prepare the Mocha Glaze
Whisk softened butter, cocoa powder, powdered sugar, and espresso until smooth and creamy.
Step 7: Glaze and Serve
Drizzle the mocha glaze over the cooled banana bread. Garnish with extra pistachios if desired. Slice and enjoy.
