How to make Soft Banana Walnut Blondies
Making Soft Banana Walnut Blondies is a straightforward process that takes just a few simple steps. You will start by preheating your oven to 175°C (350°F) and preparing an 8×8-inch baking pan. Greasing the pan and lining it with parchment paper ensures that your blondies lift out easily after baking.
Once the pan is ready, the next step involves mixing the wet ingredients. You’ll combine melted vegan stick butter or coconut oil with light brown sugar, mashed ripe banana, and vanilla extract in a large bowl. Mixing these ingredients until smooth is critical, as this forms the flavorful base of your blondies. Following this, you’ll incorporate fine sea salt, baking powder, and baking soda, ensuring these leavening agents are evenly distributed throughout the batter.
The dry ingredient, all-purpose flour, will be gently folded into the wet mixture. This is a crucial moment, as overmixing can result in dense blondies; only mix until just combined. Next, you’ll add chopped walnuts, leaving some for topping, which not only enhances flavor but also adds an attractive finish to the blondies.
Once the batter is ready, transfer it to the prepared pan, spreading it evenly. Afterward, scatter the leftover walnuts on top and pop it in the oven. Bake until the surface is lightly golden and a toothpick comes out clean, an indication that they’re perfectly done. Let them cool in the pan for a short while before transferring to a wire rack to cool completely, allowing for easier cutting.

How to serve Soft Banana Walnut Blondies
Soft Banana Walnut Blondies can be served in various delightful ways depending on your preference. They are delicious enjoyed plain, letting the natural sweetness of the banana shine through. For a more decadent experience, consider serving them warm with a dollop of whipped cream or a scoop of vanilla ice cream. This classic pairing transforms these blondies into a sumptuous dessert that is sure to impress any guests or family members gathered around the dinner table.
You might also drizzle a bit of melted chocolate or a rich caramel sauce on top for an added layer of flavor, enhancing the already delightful combination of banana and walnut. For those who enjoy textures, serving them with a sprinkle of sea salt can bring out the sweetness and offer a contrasting crunch that makes each bite more interesting.
Should you wish to make these blondies a part of a special occasion, they can also be elegantly plated with fresh fruit or garnished with a dusting of powdered sugar to give a bakery-style appeal.
How to store Soft Banana Walnut Blondies
Storing your Soft Banana Walnut Blondies is quite easy, allowing you to make them ahead of time or save leftovers for later enjoyment. Once the blondies have fully cooled, they can be stored in an airtight container at room temperature for up to three days. If you opt for refrigeration, they can last up to a week, although preserving their soft texture might be better at room temperature.
For longer storage, consider freezing them. Simply wrap individual squares in plastic wrap or aluminum foil and then place them in a freezer-safe bag or container. They should maintain their flavor and texture for up to three months in the freezer. When ready to enjoy, allow them to thaw at room temperature for a few hours or pop them in the microwave for a few seconds to soften before serving.
Tips to make Soft Banana Walnut Blondies
To achieve the best results with your Soft Banana Walnut Blondies, a few tips can enhance your baking experience. First, ensure your bananas are very ripe; the added sugars from the overripe fruit will create a more flavorful and moist blondie. Also, consider using a kitchen scale for precise measurements, especially for the flour, as this can affect the outcome of your blondies significantly.
When mixing, be careful not to overmix the batter—stop as soon as the flour is incorporated to ensure a light and chewy texture. Toasting the walnuts before adding them enhances their flavor, making your blondies even more delicious. If you prefer a stronger banana flavor, you can add an extra half banana, adjusting the flour slightly to balance the moisture.
Finally, baking times can vary based on your oven and the pan thickness, so keep an eye on the blondies during the last few minutes in the oven. Checking for doneness with a toothpick is key; it should come out clean for perfectly baked blondies.
Variation
No major variations, but you can adjust seasonings to taste.
