Notes

- Easy Mashed Potatoes - You can use your microwave to mash a russet potato by piercing the potato all over with a fork. Microwave for several minutes, rotating every few minutes until the potato is tender and can be pierced easily with a fork. Remove the inside of the potato from the skin and mash it up until you no longer have lumps.

- Let the Mashed Potatoes Cool - Let the mashed potatoes cool to room temperature before using them in the candy. If you use them when they are still warm, your dough may be too liquidy and won't come together.

- Cut into small pieces - This treat is very rich and sweet, so cut the slices small (even smaller than photographed if needed)
- Peanut Butter Alternate - Instead of Peanut Butter you could use your favorite nut butter, or even something sweeter like Nutella or Cookie Butter instead.
