Ready in minutes, this toffee takes all the guesswork out of candy making, and is by far the most requested holiday treat I make. My family won't let me in the door without a few batches in tow. Makes a great gift wrapped up in a holiday tin!

Ingredient Checklist

Directions

Instructions Checklist
  • Butter the top edges of a 2-quart microwave-safe casserole. Add butter, 1 teaspoon of the Diamond Crystal® Sea Salt, sugar, and water to the casserole. DO NOT STIR. Microwave on high for 6 to 8 minutes. Check contents for color change. Continue microwaving on high a minute at a time until the mixture just begins to turn a tan color. You need to watch it carefully, and remember: DON'T STIR.

  • Sprinkle 1/2 cup of the chopped cashews into a 9-into circle on a Silpat mat, parchment paper, or on a buttered baking sheet.

  • Carefully pour the liquid mixture evenly over the top of the cashews. Immediately sprinkle on the chocolate chips. Allow to sit for 1 minute to melt the chocolate.

  • Use spatula to smooth out chocolate over the entire sheet of candy.

  • Sprinkle the remaining cashews and 1/4 teaspoon Diamond Crystal® Sea Salt over the top. Refrigerate to cool completely. When cool, break into bite-sized pieces. Store tightly covered in refrigerator.

Tips

If the butter releases from the toffee, it probably cooked a bit too long. When it happens I just tilt the pan so that the butter runs away from the toffee before it cools. Works well with other nuts and chocolate combinations also.

This turned out amazing and was done completely in the microwave... you heard me right! This is a recipe ANYONE can do. It is delicious. I must admit while reading this I was quite skeptical. How could candy made in the microwave be any good. THIS ONE IS!!! One thing to watch out for. When they say to keep an eye on it they are not kidding. Mine took 12 minutes to turn colors but once it does it turns very quickly. Read More

I hated this recipe. The butter separated. I made it twice the first time I cooked it too long. Not stirring prevents it from separating however it does not cook evenly. The second time I made it I did not over cook. It still separated and just made a mess. Read More

Simple and delicious! I did use more cashews than called for b/c the amount didn't seem like enough to me once I put it out on the cookie sheet but that was my only change. LOVED the addition of the sea salt both inside and on top. Keep a close eye on the butter/sugar mixture as it cooks (I burned mt first batch lol). Definitely use butter for this no margarine b/c you will get a rich buttery flavor! I can't wait to make this for the holidays...a definite keeper YUM! Thanks for sharing.:) Read More

oh man oh man oh man! I love toffee and this is sooooo easy that it might turn out to be dangerous lol! I wasn't sure that I'd like all the nuts (usually I only like them on the top not in the toffee itself) but the cashews were so buttery they were the perfect compliment. Will be making this again and again for sure! Oh BTW I only had Diamond Crystal's Kosher salt and it was still terrific obviously! Read More

Checking all sorts of toffee recipes I got out my candy thermometer my heavy saucepan and figured I would be in the kitchen all night. About 8 minutes in the microwave and a few minutes scattering nuts on a Silpat I have a really good batch of toffee. Who'da thunk! This will go to friends at a lunch tomorrow so I will have to make another batch...or two...or three. Cashews...Almonds...Macadamia Nuts not to mention playing with a mix of dark and white chocolate. Now to figure out what to do with my candy thermometer! Read More

Unbelievable! Super simple to make and delicious. I used a glass mixing bowl with a handle and pour spout in the microwave to make the butter/sugar base. The handle and spout made it much easier to pour the liquid on to the cashews. I made several batches and they vairied between 8 and 10 minutes before the mixture turned a tan color. The cashews really make it special and everyone raved about it at Christmas. If only everything could be this simple and fool-proof! Read More

While I bake a lot this was my first time making toffee - the "easy" part caught my attention! I made as directed other than increasing the cashews to a full cup (3/4 cup on the bottom). I used my 4 cup glass measuring bowl for the toffee mixture. After about 4-5 minutes I noticed that the mixture looked like it was going to boil over but just when it got to the top of the bowl it went back down. Made me wonder if that was the reason for buttering the top of the container. Never did boil over even though it looked close several times. It took about 10 - 12 minutes to cook in my microwave. Timing is a bit uncertain because at about 6 minutes my microwave blew a fuse and it took a minute or so to trip it back and start the heating process again. Did not affect the end product which turned out so tasty! I like the addition of the nuts in the toffee base and the flavor is wonderful. Can't wait to share! Read More

delicious and so quick and easy to make. I've made it several times with no changes. Also have made it using different nuts and/or adding broken pretzels. Give this recipe a try. You won't be disappointed. Read More

I've never made toffee in the microwave so I was a little skeptical that this could be that good. It is THAT good! And it just doesn't get much easier. I also made a variation with hazelnuts (which I needed to use up) and dark chocolate sprinkled with sea salt which was incredibly good. I'd be sure to use a good quality chocolate in this one.
