Ingredients Notes

  • Unsalted Butter: I love how melting it adds richness, enhancing moisture. Use high-quality butter for a deeper, more pronounced flavor.
  • Brown Sugar: I prefer packed brown sugar for its caramel-like flavor which deepens the blondies’ sweetness.
  • Egg: Acts as a binder, and using a fresh large egg ensures perfect structure and moisture.
  • Vanilla Extract: Pure vanilla extract always imparts a warmer, inviting aroma to the blondies.
  • Ripe Bananas: The riper, the better for sweetness and flavor. They naturally sweeten and moisten the batter.
  • All-Purpose Flour: Provides structure; ensure it’s fresh for the fluffiest texture.
  • Baking Powder: Ensures the batter rises perfectly, resulting in a tender crumb.
  • Baking Soda: Reacts with banana acids for a light, fluffy texture.
  • Cinnamon (Optional): Perfect for adding warmth; lightly dust for a subtle spiced note.
  • Salt: Balances out the sweetness, enhancing all other flavors.
  • Optional Mix-Ins: I add nuts or chocolate for texture and extra flavor. Use high-quality for maximum enjoyment.

How to Make Banana Blondies?

  • Prepare Your Ingredients: Gather all your ingredients and let them sit at room temperature. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, allowing the edges to hang over for easy lifting. 
  • Mix the Wet Ingredients: In a large mixing bowl, combine the melted unsalted butter and packed brown sugar. Whisk until the mixture is smooth and slightly pale in color. This step creates the base for your blondies, offering a rich, caramelly aroma. Add the egg and vanilla extract, whisking until fully incorporated and glossy. 
  • Mash the Bananas: In a separate bowl, mash the ripe bananas using a fork until mostly smooth with just a few small lumps to add texture. The ripe bananas will emit a sweet, inviting fragrance. 
  • Combine Wet and Dry Ingredients: Gradually stir the mashed bananas into the butter mixture, maintaining a uniform consistency. In another bowl, whisk together the all-purpose flour, baking powder, baking soda, optional cinnamon, and salt. Fold the dry ingredients into the wet mixture just until combined, ensuring not to overmix to maintain a tender crumb. 
  • Add Mix-Ins (Optional): Gently fold in the optional mix-ins like chopped walnuts, pecans, or chocolate chips for added texture and flavor. 
  • Bake: Pour the batter into the prepared baking dish, smoothing the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached. 
  • Cool and Serve: Allow the blondies to cool in the pan for about 10 minutes, then use the parchment overhang to lift them out and place on a wire rack to cool completely. Cut into squares, enjoy the chewy texture with a slight crunch on the edges, and savor the delightful, banana-laced aroma. 

Expert Cooking Tips

  • Bake until the edges are golden for the perfect balance of fudgy and firm texture.
  • I always mash bananas well for a smoother batter and even banana distribution.
  • Use overripe bananas for a more intense flavor and better moisture retention.
  • Consider mixing by hand to avoid overworking the batter, which can lead to dense blondies.
  • I incorporate chocolate chunks for a gooey texture burst in each bite.
  • Cool completely before slicing to maintain the structure and prevent crumbling.
  • Check doneness with a toothpick: it should come out mostly clean with some moist crumbs.
  • Use parchment paper in the baking dish for easy removal and clean edges.
  • Sift flour and sugar to eliminate lumps and ensure even mixing.

Storage Tips

  • Store your Banana Blondies in an airtight container at room temperature for up to 3 days for freshness.
  • For longer storage, refrigerate blondies for up to a week in a sealed container.
  • Wrap individual blondies in plastic wrap before freezing to prevent freezer burn.
  • Defrost in the refrigerator overnight to maintain texture and moisture.
  • Reheat in a 300°F oven for 5-10 minutes for a fresh-baked aroma and warm texture.
  • Ensure blondies are fully cooled before storing to prevent condensation and sogginess.
  • Keep stored blondies away from strong-smelling foods in the fridge or freezer.
  • Layer parchment paper between blondies in storage to prevent sticking.
  • Always check for any off smells or mold before consuming stored blondies.

Variations and Substitutions

  • For a dairy-free option, substitute butter with a vegan margarine or coconut oil.
  • Use gluten-free all-purpose flour to make the recipe suitable for gluten-sensitive diets.
  • Add chopped nuts, such as walnuts or pecans, for a crunchy, nutty variation.
  • Incorporate raisins or dried cranberries for a fruity twist.
  • I love adding a swirl of peanut butter for a nutty, rich flavor.
  • For a chocolatey version, replace some flour with cocoa powder and add chocolate chips.
  • Include a dash of cinnamon or nutmeg for a warm, spiced flavor.
  • Use almond or oat milk in place of dairy milk for a subtle change.
  • Substitute part of the brown sugar with coconut sugar for a distinct caramel note.
