FREQUENTLY ASKED QUESTIONS:
It’s a very simple ingredient list: mashed potatoes, butter, vanilla, powdered sugar and peanut butter.
Like many recipes that have changed over time, it is hard to pinpoint exactly where it started. It is believed that this candy evolved from a recipe that was brought to America by German immigrants. That “recipe” had only two ingredients: potatoes and sugar. And as time went on, it took on the addition of peanut butter as it became popular (and was affordable) during the First World War.
Irish Potato Candy is shaped to look like a potato with a dusting of cocoa powder on the outside. It doesn’t contain any peanut butter.
Russet potatoes. You will only want to use that potato for this recipe. I have not tested with any other potatoes as this is how we have always made it.
No. Sorry. Do not use instant potatoes in this recipe as they are too watery and you will not get the consistency desired.
Poke holes in the potato and microwave until tender. Let it cool completely, peel and then mash. This method makes the potato less watery, needing less powdered sugar.
Traditionally this calls for creamy peanut butter but you can use crunchy for a little bit of texture change. Just make sure that when you spread it on the potato mixture, it does not rip or poke holes in it. I do not recommend natural peanut butter as it is too oily of a consistency.
Yes, if you don’t usually keep salted butter in your home you can use unsalted just add a little bit of salt (about 1/4 teaspoon) to the mixture.
Yes, you can make this up to 1 day ahead of time. Remove from the refrigerator and let it almost come to room temperature (you still want it to be slightly chilled) and cut.
You can store Grandma’s Potato Candy Recipe in an airtight container where it will keep in the refrigerator or up to 3 days.

INGREDIENTS NEEDED: (FULL RECIPE AT THE BOTTOM OF THE POST)
- mashed potatoes
- salted butter
- vanilla extract
- powdered sugar
- creamy peanut butter

HOW TO MAKE POTATO CANDY:
Place the cooled mashed potatoes into a large bowl. Add the butter and beat with an electric hand mixer until smooth. Add the vanilla and stir in until combined.

Slowly add in the powdered sugar 1 cup at a time, fully mixing in the first cup before adding the next. How much you use depends on how watery your mashed potato is as well as humidity, etc.

You want the consistency to be like cookie dough that you can roll out. When you put a little bit in your fingers you should be able to press and mold it together.

In this step, you have to work pretty quickly because it can dry out. Layout a large piece of wax or parchment paper, dust it generously with powdered sugar. Place the potato mixture on the paper, add a generous amount of powdered sugar on top.

Roll it out to ¼ inch thick. Try to get this into a rectangle shape as well as you can.

Smear the peanut butter all over the top leaving a half-inch border.

Tightly roll into a long log. Place on a piece of plastic wrap and roll the log up and tuck the ends under. Place in the refrigerator for 10 minutes to set.

Unwrap on a cutting board and cut into ¼-½ inch slices to serve.

Serve and enjoy!

I love potato candy. Seeing this really makes me miss my mom and my great-granny. They would color it according to the holiday/occasion.
Honestly, the best part about sharing these older recipes is hearing about everyones memories of them. Also, I love that they added food coloring to match the holiday. How sweet!
My mother made this and we kids loved it. Brings back good memories, and I’m going to make this.
I love that it brings back good memories for you! Thank you!
