After a successful Thanksgiving dinner, I had leftover mashed potatoes and wasn't ready to throw them away. Mashed Potato Brownies were the result! This recipe is originally from the Wisconsin Potato council. I modified it a slightly by using unsalted butter and increasing the salt. I also made a half batch using an 8 inch square pan, but below is the full batch recipe.
This is a fun way to use leftover potatoes. The brownies taste great and have an interesting texture....like baked potatoes maybe? Okay, not really. But the texture is a little different.
Mashed Potato Brownies Tips
It should go without saying that Mashed Potato Brownies should be made with unseasoned mashed potatoes. Potatoes seasoned with salt and butter (and maybe even pepper) will be fine, but don't use potatoes with garlic powder or onion. If you are making potatoes ahead of time and thinking about making these brownies later, maybe scoop out a cup before you add further seasonings.
Another Fun Potato Recipe
If you're not in the mood for brownies, here's another fun potato recipe that's popular around Easter -- Secret Ingredient Chocolate Coconut Eggs.

Instructions
- Preheat oven to 350°F. Line a 13x9 inch metal pan with foil and grease foil.

Wow, glad to hear the flavor of the chicken stock didn't come through. Thanks for trying these and commenting 🙂

I made these this weekend. I had leftover mashed potato (I used chicken stock to make them). My pasrtner was pretty doubtfull, but when they came out the oven and we tasted them he was pleasantly surprised (no chicken flavour lol). I didn't add salt because of the salt in the mashed potato. I also refuse to keep semi-sweet chocolate at home, so the chocolate chips were dark chocolate, and I only had flaked almonds. Divine.

I wonder if pumpkin would work also
Jenn's Baking Chamber says
Very interesting! I like this idea, i bet the texture was terrific!
Lisa Ernst says
I was curious too, if sweet potatoes would work. They do have a stronger flavor, but are full of nutrients.

I also leave the onion powder out of the potato recipe, but unfortunately, the small amount of potatoes left over were gobbled up by my 15 year old this morning for breakfast!
Amazing that you baked today!
Kim says
Those look great!
Too bad we never have any mashed potatoes left. No matter how much I make, they're always gobbled up.
Got any recipes for stuffing brownies?
Sophia says
Wow! Makes me wish I had brought home more leftovers.
Oh, btw I made your Pecan Pie (in the family recipe crust) and it was a huge hit at our family's Thanksgiving.
Sara says
This sounds really unique - I usually make potato rosemary bread with my leftover mashed potatoes!
Joanna says
Oh wow!! Anna, I'm surprised you baked something today!! I figured you'd just want to eat leftovers. These look so delicious. I'm mad because I put garlic powder and onion powder in my mashed potatoes! I so would've tried these because there was no chocolate last night and I need some!
Katrina says
Cool! I'm from Idaho, so I think potato stuff is cool! I have a whole cookbook with all things potato. Even some Almond Joy candy bars, made with leftover mashed potoates that are so good and you can't even tell. Maybe I'll make those for Christmas.
Glad the day and dinner was a success! I'll have to try that pumpkin pie recipe! Good job, Fuzz!
Hallie says
The potatoes in the brownies while unusual, probably makes the texture really creamy and nice. I love these interesting recipes you always find.
clumbsycookie says
Glad you enjoyed your evening! So you managed to find another mashed potato brownie with no almond flour. I belive they're good, cause I really liked mine I did with mashed potatoes a while back. I bet Fuzz was happy to have won the best pie ;)!
patsyk says
You wouldn't know there were mashed potatoes in them from that picture! I'll have to make sure to save some to the side next time we have them so we can try these out!

Well...I am glad your Thanksgiving went well!
Mash potatoes in brownies....I bet those are awesome! One of my favorite cinnamon roll recipes is an Amish recipe made with mashed potatoes.
I will have to check this recipe out.
VeggieGirl says
