Sorry I didn't get back to this post. I will include my fudge recipe. Well, it is my sister Pat's recipe.
"Quick Peanut Butter Fudge"
2 cups sugar
6 Tbsp butter
1 cup evaporated milk, not sweetened.
Mix and cook in an electric skillet at 280 degrees. Stir and bring to a boil. Allow to boil for 5 minutes. Avoid stirring but watch it doesn't scorch on bottom, adjust temp as needed.
Turn off and add:
1 1/3 cup peanut butter
1 tsp. vanilla
1 cup miniature marshmallows. Smash those babies into the cup firmly and it should be closer to 1 1/2 cups.
Beat, by hand, the fudge till the shine dulls and it begins to get stiff. Place in buttered 8x8 dish.
I have used a regular sauce pan and candy thermometer (mine is broken) and it is okay. The electric skillet is actually easier.
I have also used regular sized marshmallows but cut them in halves or smaller so the melt quickly.
I have doubled the recipe and it turned out fine doing both in the skillet.
