Rated as 4.86 out of 5 Stars

"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!"

  1. Butter the top edges of a 2-quart microwave-safe casserole. Add butter, 1 teaspoon of the Diamond Crystal(R) 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.
  2. 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.
  3. 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.
  4. Use spatula to smooth out chocolate over the entire sheet of candy.
  5. Sprinkle the remaining cashews and 1/4 teaspoon Diamond Crystal(R) Sea Salt over the top. Refrigerate to cool completely. When cool, break into bite-sized pieces. Store tightly covered in refrigerator.


  • 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.

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...
