Krispie Toffee Triangles

Why I Love This Recipe
While at the library 1500 Best Bars, Cookies, Muffins, Cakes & More by Esther Brody caught my eye. This book is great, there are so many good recipes in it I am going to buy the book. The Krispie Toffee Triangles is the first recipe I decided to try. The rice krispies with the chocolate was a great combo on the top. We are thinking of where else you could use this in a recipe. It is a very nice bar. Would be a nice addition to your Christmas baking.
