Healthier Vegan Banana Blondies

These vegan banana blondies are light and cake-like yet rich, a cross between banana bread and a healthy blondie! Easy to whip up when you have a couple of overripe bananas on hand, they are also free from gluten and easily made nut-free. Try them warm with a scoop of vanilla oat milk ice cream!

My oil-free banana brownies are one of the most popular recipes on the blog. The cocoa and bananas come together to create a light brownie that tastes so much better than the sum of its parts!

Those brownies are really light at just 120 calories each, and y'all can't get enough of them! So I figured why not transform that recipe into a blondie, with chocolate chips added to the batter and hand-chopped chunks of chocolate added to the top for glorious, melted pools of chocolate.

The batter for these vegan blondies is also nut-free since we're using tahini instead of the almond butter used in the brownies. Simply omit the walnuts for a nut-free vegan dessert.

Equipment and Ingredients

You'll need a mixing bowl, another smaller bowl, parchment paper, an 8-inch square baking pan, and these 12 ingredients:

2 large overripe bananas - they should smell very sweet
⅓ to ½ cup tahini - depending on how rich you want the blondies to be
¼ cup non-dairy milk - I used unsweetened oat
¼ cup coconut sugar
2 teaspoon vanilla extract
2 teaspoon apple cider vinegar
1 ½ cups oat flour (150 grams) - if not using a scale be sure to whisk the flour first to fluff it up before measuring
½ teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon fine sea salt
⅓ cup walnut pieces
⅓ cup dairy-free chocolate chips plus more for the top, or...
1 ½ ounces dark chocolate, chopped

FAQs and Tips

What is a blondie anyway?

Blondies are essentially the vanilla version of a brownie. They are usually made with flour, butter, and eggs, and contain nuts like walnuts or pecans. So with the addition of banana, you can already tell these aren't traditional. On top of that, they're vegan and healthy-ish.

Are these rich and dense like traditional blondies?

That's an easy answer.... nope. The batter for these banana blondies is actually oil-free and refined sugar-free, so they're on the lighter side. However, they are fairly sweet! Expect a moist, banana-y, gooey-yet-cake-like texture that won't leave you feeling like you ate a brick. But with the chocolate and walnuts they're still a very satisfying dessert.

What can I substitute for oat flour?

I haven't tested these blondies with other flours yet but suspect another whole-grain flour will work. You know me.... oat flour is my go-to for baked goods!

How long do they keep?

I like to play it safe and store the blondies in the refrigerator. Similar to other moist baked goods, it's best to enjoy them within 4 to 5 days.

Can I freeze banana blondies?

Definitely! Just make sure they're cool, then place in an airtight container and freeze for up to a month. They thaw fairly quickly, so move them to the fridge an hour or two before you plan to eat/serve.

Ideas for Serving

After the recommended cooling time, the blondies are still slightly warm in the middle, which means irresistible, melted chocolate chips. Enjoy right away with a glass of your favorite non-dairy milk or a scoop of Vanilla-Maple Oat Ice Cream.

Leftover banana blondies can be enjoyed straight from the fridge, although they're even better slightly warm. About 15 seconds in the microwave does the trick. Prepare to swoon!

If you're a fan of yogurt, these taste fantastic with a dollop of cool and tangy plain cashew yogurt or your favorite sweetened vanilla yogurt.

Equipment

Ingredients

Dry ingredients:

1 ½ cups oat flour (150 g) - Use certified gluten-free oat flour if needed.
½ teaspoon baking soda
½ teaspoon baking powder
¼ teaspoon fine sea salt

Wet ingredients:

1 cup mashed overripe banana (about 2 large bananas) - Use bananas with a lot of dark spots.
⅓ to ½ cup tahini (use ½ cup for richer blondies) - Or sub your favorite nut/seed butter; will alter flavor and color.
¼ cup unsweetened plant milk, such as oat or soy
2 teaspoons vanilla extract
2 teaspoons apple cider vinegar
¼ cup coconut sugar - Or your favorite granulated sweetener.

Additions:

⅓ cup dairy-free chocolate chips - Plus more for the top if not using dark chocolate listed below.
⅓ cup chopped raw walnuts, divided - Omit for nut-free.
1 ½ ounces dairy-free dark chocolate, chopped, optional - For sprinkling on top.

Instructions

Preheat oven to 350 degrees F and line an 8x8 baking pan with parchment paper.
Place peeled bananas in a mixing bowl and thoroughly mash with a fork. Add the tahini, milk, vanilla, vinegar, and sugar. Whisk until combined.
In a separate bowl whisk together the oat flour, baking powder and soda, and salt. Pour dry ingredients into the banana mixture, and stir to combine. Fold in the chocolate chips and most of the walnuts, reserving a palmful of nuts for the top.
Transfer batter to the prepared pan, and sprinkle the top with chocolate chunks and reserved walnuts. Bake for 23 to 27 minutes or until the center appears set and gives only slightly when pressed.
Allow to rest in the pan for 15 minutes, then lift out by parchment paper onto a cooling rack. Let the blondies cool for at least 20 to 30 minutes before cutting into squares.

Notes

Store blondies in an airtight container in the refrigerator for up to 5 days. If you need to stack them, just fold over the existing parchment paper or place a new piece of parchment between the layers to keep them from sticking together.

Banana blondies can also be frozen. From frozen, they thaw fairly quickly. Transfer to the refrigerator about an hour or two before serving.

Serving Suggestions

These taste great straight out of the fridge and even better when slightly warm! Warm them in the microwave for 15 to 20 seconds, and serve with whipped coconut cream or vanilla oat milk ice cream. Delicious!
