1- Ready to get your hands messy? Let’s walk through making these banana blondies step by step it’s easier than you think, and I’ll add some fun tips along the way. Start by preheating your oven to 350°F and lining an 8×8 baking dish with parchment paper; give it a light coat of nonstick spray to keep things from sticking. This little prep makes cleanup a snap, trust me, it’s a game-changer!

2- Next, melt the butter in a large pan, and if you want that extra nutty flavor, keep swirling it until it turns a deep golden amber color let it cool for about 5 minutes. Stir in the packed light brown sugar, vanilla extract, and kosher salt until everything’s nicely combined, then mix in the egg until smooth. Fold in the all-purpose flour and mashed banana (from about one medium banana) to keep the batter light and airy. Don’t overmix, or you’ll end up with tough blondies I’ve been there, and it’s not pretty!

3- Spread the batter evenly in your prepared pan and pop it in the oven for about 30 minutes, or until the center is set. Once done, let the blondies cool on a wire rack before adding the frosting. For the frosting, melt 1/4 cup butter in a saucepan, add 1/2 cup light brown sugar and 2 tablespoons milk, stirring until it just boils, then cool for 5 minutes and whisk in 1 cup powdered sugar until smooth. Spread it over the mostly cooled blondies and let it set before cutting into 12 pieces. The whole process takes about 50 minutes total, with 20 minutes prep and 30 minutes cooking perfect for a quick dessert.
