This didn't seem to turn out, but I believe that's all my fault. My microwave is slow and I was getting nervous because it had already been cooking for over 12 minutes. I should have left it in a little longer. The edges are great - taste just like toffee. But the center is pretty much just sugar. It appears that the butter spread out to the edges which is why it tasted more like toffee there. I'm out of nuts, so I didn't use any, but I sprinkled chocolate chips on top. Still tastes good!
Very easy to make, it came out perfectly!!! A +++++
I'm gonna try to make this on the week-end. I love toffee. I make pecan brittle in the microwave and it is absolutely delicious!! Hope this works for me....I'll rate it after I make it!!
