My recipe is exactly like this one. Also try this variation: Almond Brittle - Instead of peanuts and vanilla, add one (7 oz) jar dry roasted almonds and 1 teaspoon almond extract. Omit butter and add 1 cup (4 oz) shredded coconut with extract. I have also used pecans or cashews! Excellent!

This is the same recipe I have - I must make 15 batches and give as hostess or gift toppers. It is the best.

I made over 30 batches of this for the holidays, Everyone loved it I also made it with the almonds it was excellent as well. The comments I recieved were about the flavor and how easy it was to chew. I used the planters salted peanuts for the best results. I am looking for a good method to clean the glass pyrex measuring cup after each batch? Thank you, Big Eater
