Double Chocolate Mashed Potato Brownies

Happy Black Friday. I haven’t ventured out of the house yet because I’m too busy basking in the glow of Thanksgiving success. Everything turned out great — even the turkey, though it tested my patience. The fancy digital thermometer said the turkey was done an hour earlier than anticipated. I didn’t believe the thermometer, cut into the turkey, and had to make a judgment call. There was some pink, so I stuck it back in the oven, lowered the temp, moved the thermometer and let it go another 45 minutes. By some miracle, it was perfect. The only disappointment was that my 9.75 pound turkey barely had any white meat. Are they raising big boned birds these days?

So aside from the turkey and another issue involving the neighbor’s rabbit and a locksmith (don’t ask), the meal and company were as good as could be expected.

Of all the dishes, my favorite was Fuzz’s pumpkin pie, which was made with condensed milk (as opposed to evaporated). The pie, which got all of its sweetness from the pumpkin and the condensed milk, had a very smooth texture and great flavor. I’m going to make another one with sweet potatoes.

Speaking of potatoes, the make-ahead mashed potatoes were a hit with the little kids. I’m glad I didn’t add any onion powder, because I was able to use the leftovers in today’s brownie. This recipe is from the Wisconsin Potato council. I modified it a slightly by using unsalted butter and upping 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 tasted great and had an interesting texture….like baked potatoes maybe? Okay, not really. But the texture was a little different….not in a bad way.

    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.

    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!

    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 ;)!

    The potatoes in the brownies while unusual, probably makes the texture really creamy and nice. I love these interesting recipes you always find.

  6. 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!

    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!

    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.

    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?

  10. says

    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!
