Mix together in a large pan:
3/4 c butter
Bring to a boil and cook for 3 minutes.
Turn off heat and add:
1 (3.9 oz) pkg instant chocolate pudding mix
3.5 - 4 c oats
1/2 t vanilla
Mix well, cover and let stand 10 minutes. Then drop by spoonfuls onto wax paper, or press into a pan and cut after cool.
The recipe said different flavored pudding mixes can be used for variety. Also, I used sugar-free mix since that's what I had, but had I used regular mix, the calorie count probably would of been higher. Next time I might add some nuts or dried fruit. I'm pretty happy I came across this one.
