Super Spud Brownies

These moist and cakey brownies came from my mom’s old cookbook. Mashed potatoes may seem like an unusual ingredient, but this recipe took first place at a local festival. —Marlene Gerer, Denton, Montana

    I Just tried this recipe with a few modifications. I decided to use mashed sweet potatoes and substituted the mashed bananas for the eggs to make the recipe vegan. In all, my only complaint about the recipe is that prep time took longer than 15 minutes. I also think that these brownies leave something to be desired with their flavor. While it is definitely chocolatey, there's not much else to it. I think next time I use this recipe I will replace the Confectioners' sugar with cinnamon. Overall, I really like this recipe and enjoyed making it! Definitely a great use of leftover mashed potatoes.

    These were good. I used regular potatoes. I don't purchase instant potatoes. No one could believe that they had mashed potatoes in them. Thanks.

    I can't believe these "cooks" are asking if the potatoes are instant. When cooking with potatoes, in cakes, cookies, or spudnuts, always use freshly cooked potatoes...the kind that grow in the ground. I have also made this cake many times, and everyone loves it. I never use instant potatoes, except to thicken up soup. I keep a small box in the frig for only that.

    Made them and didn't like them at all. I used instant potatoes and made a cup of them. No one in my family liked them. They were too much like a cake and there wasn't enough chocolate flavour. I will admit that withy were moist. Will not make them again....sorry!

    Thank you des432, that makes perfect sense, I wondered about the milk, salt, pepper, butter and whatever else you mix with the mashed potatoes?

    I wonder if the recipe should have said cooked potato, mashed with fork? When you make potato candy, that is what you use. The potato turns liguidy when it's mixed with sugar. Just a thought

    Since the recipe said "mashed" potatoes, I figured it meant already prepared, or leftover potatoes. Otherwise it would have said potato flakes or something like that.

    No one mentioned, are these dry mashed potatoes? or alredy prepared mashed potatoes?

    These were so unbelievably good! My husband didn't believe that there were mashed potatoes in them until I showed him the recipe. You really can't taste the mashed potatoes at all.
