English Toffee Easy Microwave Recipe

I have been making this recipe for the last 20 years and it is so easy. The recipe came from Karo Syrup. I clipped it from a magazine ad featuring recipes using Karo Light Syrup. The ingredients are sugar, butter, corn syrup, chocolate chips and chopped almonds.

I have a grandchild that can’t have nuts so I leave out the almonds in the toffee and leave some of the top with out nuts for him. This is going to be teacher Christmas gifts this year.

English Toffee Easy Microwave Recipe


  • 2 cups sugar
  • 1/2 cup water
  • 1 cup butter (2 sticks) no substitute
  • 1/3 cup Karo corn syrup (light)
  • 1/4 teaspoon salt
  • 2 teaspoons vanilla
  • 2 cups chocolate chips
  • 1-2 cups chopped almonds


Prepare a 15 inch x 10 inch x 1 inch with vegetable spray or grease with shortening. You will need a candy thermometer. If you

In a large microwave safe bowl combine sugar, water, corn syrup, salt and butter cut into pieces. Microwave for 5 minutes and stir. Return to microwave and continue cooking, stirring every 7 minutes for about 18 to 20 minutes. The time depends on your microwave. The mixture will turn golden brown. Check with candy thermometer and when it reaches hard crack stage (about 300 degrees) it is done.

At this point you add the vanilla and it will sputter as you stir it in. You can also add almonds to the mixture if desired. Pour on the prepared pan and spread out evenly.

Sprinkle the top with chocolate chips and let melt for 5 minutes. Spread evenly the melted chocolate over the top. Sprinkle with chopped nuts.

Let cool until toffee is harden. Place pan in refrigerator for 10 minutes so the chocolate is hard on top before breaking into pieces. You will need to bang the pan on the counter first to start the breaking.

Store in tight container in a cool place.

    mmm. . . this looks wonderful. I got some toffee for a Christmas gift, and I’m trying to only eat a piece a day (but it’s difficult because it’s so tasty).

      Thanks for letting me know. I must have been side tracked with Christmas and it is harder to write a recipe that you made for a long time. I fixed it. You add the vanilla after it hit hard crack stage. Careful with it because it will sputter as you add it. The mixture is really blazing hot. I used to make it on the stove top but this way is faster. Thanks for taking the time to point this out.
