I make a cheater's fudge that people seem to go ga ga over and it's SOOOO easy. I've done this alot when it's last minute and I have to make something. Also good when it's warm out, you don't have to use the oven.
What you'll need:
1 can chocolate frosting (not whipped kind, regular kind)
1 smaller bag (I think 8 oz?) of chocolate chips
1/4 tsp. of vanilla
1 candy bar (snickers was the one I was told about first, but have used all sorts of them, toffee ones are another hit, as is butterfingers)
Chop up candy bar into small bits.
In microwave, melt chocolate chips until they are just melted.
Fold in the chocolate frosting and vanilla and 3/4 of the candy bar.
Spread into a square (8x8) pan (I like to spray mine first with No stick spray like Pam, but you don't have to) and then sprinkle the rest of the candy bar on top.
Let set.
That's it! I cut them into small squares and put them in baggies or on little plates. Sell them in sets of 6.
