Sweet Potato Benefits

Sweet potatoes are rich in Vitamin A. In fact, one sweet potato accounts for approximately 400% of the daily recommended Vitamin A.

An antioxidant called carotenoids give sweet potatoes their bright and vibrant coloration.

This superfood is great in both sweet and savory dishes. In recipes like this one, it is very reminiscent of pumpkin. Sweet potatoes are common around the holidays, especially Thanksgiving, but they are great all year long!

Ingredients & Substitutions

Roasted sweet potatoes are at the heart of these blondies! I do not recommend substituting pumpkin purée because it is significantly more moist than sweet potato. In addition, I do not recommend using canned sweet potatoes or canned yam. They are also too moist.

Almond butter works best because it is more mild in taste than peanut butter or cashew butter. Use creamy almond butter!

Substitute honey for maple syrup if desired.

The almond flour is the best flour for these. If necessary, use 2 tablespoons coconut flour in its place.

The eggs are vital to binding these gluten free sweet potato bars together. An egg replacement or flax eggs do not work.

Feel free to use any nuts or chocolate chips on top!

Expert Tips & Tricks

Fully roast sweet potatoes until they are tender. The act of roasting them also slightly caramelizes them. This adds the best flavor to the bars!

Use creamy almond butter for best results.

Process mixture until fully smooth and creamy.

Bake until a toothpick inserted comes out clean.

Allow blondies to fully cool in fridge before slicing and serving. They are very gooey!

Store leftovers in the fridge. They will be too gooey at room temperature.

How to Serve & Store

Serve fully cooled and sliced sweet potato blondies.

Store leftovers in an airtight container in the fridge for up to 5 days.

I haven’t tried freezing these, but I wouldn’t recommend doing so.

Frequently Asked Questions

Can I use another flour?

If needed, substitute 2 tablespoons coconut flour for the 1/3 cup almond flour. Coconut flour is much more absorbent, so only a little bit is needed.

Can I use an egg replacement?

Due to the texture of these bars, I do not recommend an egg replacement.

Would pumpkin work in place of the sweet potato?

Unfortunately pumpkin is too watery for this recipe.

Can I use canned sweet potatoes?

Similar to pumpkin, canned sweet potatoes are too watery for this recipe.

How do I roast sweet potatoes?

Wrap sweet potatoes in tin foil. Pierce several times with a fork. Roast at 400 degrees Fahrenheit for an hour or until fork tender.

Ingredients

  • First, preheat oven to 400 degrees Fahrenheit. Wrap sweet potatoes in tin foil and pierce with fork several times. Place on baking sheet.
  • Roast sweet potatoes for an hour, or until potatoes are fork tender.
  • Once tender, remove from oven. Carefully unwrap and peel potatoes.

Notes

  • About 2 large sweet potatoes are sufficient for this recipe.
  • Use creamy nut butter, not crunchy.  Almond butter works best, but cashew butter and peanut butter work as well.
  • Process batter until fully smooth and creamy.
  • Do not forget to lower oven temperature to 350 degrees Fahrenheit before baking blondies.
  • Allow blondies to cool completely in the fridge before slicing and serving.
