The above doesn't have the crispy rice cereal in it as I prepared it in advance for a Carmel Apple Pizza (will post that on 10/20/11 as it is part of food challenge by Lady Behind The Curtain) but I did also try it on ice cream mixing in the cereal after heating and it was delicious.
Melt the butter in a pan. Saute the almonds over medium-low heat for approximately 5 minutes or until the almonds brown.
Add the corn syrup, water and brown sugar to the pan and mix thoroughly.
Add peanut butter and mix. Cook for 4-5 minutes until it becomes bubbly and starts to thicken up.
If serving over ice cream, add crisp rice cereal and stir in and the spoon over ice cream.
If storing, do not add Crisp Rice cereal until just before ready to serve. Heat up first (put in bowl and microwaved) then add Crisp Rice cereal and pour over ice cream.
