Preheat oven to 300 degrees. Place Ritz crackers in a single layer on a baking sheet. Then add a dollop of marshmallow cream to each cracker. The marshmallow cream is sticky, so I found that it helped to use two spoons. Sprinkle with chopped peanuts.
Center one Rolo candy on top of each cracker.
Bake for about 3 minutes, or until the Rolo just starts to soften. Remove from oven and press each candy with the back of a spoon to flatten.
