Sweet Potato Blondies

The perfect combination of cakey and fudgy, these plant-based Sweet Potato Blondies are a delicious dessert you can feel good about eating.

Looking back at the dessert recipes I've shared so far, I'm quite surprised by the number of them that contain chocolate. I definitely appreciate the taste of chocolate. But I'm the first to admit that I'll take vanilla over chocolate every time. I'm sure I've just offended 90% of you. I hope you continue to indulge me anyway, because these Sweet Potato Blondies are incredibly tasty. (BUT if you're really looking for chocolate, check out these Sweet Potato Brownies.)

Fudgy Blondies

I love this recipe because it produces blondies that are both fudgy and cakey. I credit the perfect combination of ingredients. The fudge factor: cashew butter and Japanese sweet potato.

Cashew butter is a pretty neutral nut butter but it adds a bit of sweetness and provides the needed fat in this recipe for ultra fudgy goodness. For extra creaminess, make your own cashew butter using this recipe.

And, Japanese sweet potato. By nature Japanese sweet potatoes are very sweet with a vanilla flavor. I steamed the potato to retain its moisture and the density of the potato adds to the fudgyness.

Cakey Blondies

The cakeyness comes from the dry ingredients, of course. Date sugar for sweetness. Oat flour, a classic. And the 'secret' ingredient: buckwheat flour. The buckwheat flour gives a nutty flavor. It soaks up more moisture than oat flour, making it the perfect addition to balance out the fudge.

Throw in some baking powder and baking soda for good measure and you've got yourself some amazing blondies.

But don't bake them quite yet. These blondies will be great by themselves but they are even better with some yummy add-ins! For these pictures I threw in some golden raisins. But walnuts, macadamia nuts, or coconut flakes would be amazing too. Maybe even a combination of all four?!

Hi Becky - thanks for pointing this out. I have removed mention of vegetable broth from this post. You do not need any vegetable broth. The mushrooms will release natural liquid which will prevent any sticking.

You mention using vegetable broth in your introduction but it isn’t included in the recipe

thank you for the oil free recipe. I'm getting introduced to wild Bolete mushrooms here in Colorado, and everyone sautes Bolete's in butter or olive oil. I'm on a veggie, oil free regimen for heart health reasons. and your recipe suggestion may fill the bill. I can't wait to give it a try.
