Easy Microwave Toffee

Forget the stovetop! This easy microwave toffee can be made in just 15 minutes. Your holiday goodie trays will never be the same!

A plate with a pile of easy microwave toffee.

First off, I’d like to tell you that candy making is not my forte. It’s finicky, messy, and frankly kind of stressful. So I usually avoid it like the plague, except for during the holidays. I’ve mastered a few recipes, including this almost fool-proof microwave toffee. 

You heard that right. It’s made in the microwave. ✨ No stovetop needed.

It’s made in a big bowl and then poured onto a silicone baking mat. Toasted pecans and flaky sea salt make it extra amazing!

Once the easy microwave toffee is set, it gets broken into a sheet full of big pieces.

It took me three painstaking tries to get this recipe right. Like I mentioned above, candy making can sometimes be finicky. Humidity and altitude play a big part in it as well as temperature (or microwave wattage in this case).

The most important thing you can do is keep an eye on it as it cooks (watch for color cues) and use a thermometer.

How to make microwave toffee:

  1. Grab a large glass microwave-safe bowl, combine the butter, sugars, salt, corn syrup, and water.
  2. Microwave for 3 minutes on HIGH.
  3. Stir in toasted chopped pecans or stir and keep it plain.
  4. Microwave for 8-10 minutes on HIGH or until it reaches 300 degrees on an instant read thermometer.
  5. Spread onto a silicone lined baking sheet into an even layer. 
  6. Add chocolate chips, let melt then spread over top. Sprinkle on nuts and sea salt.
  7. Chill until set, then break into pieces.

If pecans aren’t your thing, you could easily switch them out for almonds, cashews or even macadamia nuts (I’d highly suggest using white chocolate on top instead of semisweet for the latter).

We devour this toffee every time we make it. It’s perfect for holiday dessert trays, gift giving or for Santa’s cookie plate. It has quickly become a favorite at our house, I hope it will become a favorite of yours too!

Ingredients

For the base:
  • 1 c. 2 sticks unsalted butter
  • 1 c. granulated sugar
  • 1/2 c. brown sugar - packed
  • 1 tsp. coarse kosher sea salt
  • 2 tbsp. water
  • 1 tbsp. light corn syrup
  • 1/4 c. chopped toasted nuts - pecans, almonds, cashews, macadamia nuts
For the topping:
  • 6 oz. chopped chocolate or chocolate chips - milk, semisweet, bittersweet or white
  • 1/4 c. chopped toasted nuts - pecans, almonds, cashews, macadamia nuts
  • pinch flaky sea salt

Instructions

  • Line a baking sheet with silicone baking mat or parchment paper, set aside.
  • In a large glass microwave-safe bowl (4 quart is best), combine the butter, sugars, salt, water, and corn syrup.
  • Microwave for 3 minutes on HIGH.
  • Stir in chopped nuts.
  • Microwave for 8-10 minutes on HIGH or until it reaches 300 degrees on an instant read thermometer.
  • Quickly pour and spread onto a silicone lined baking sheet into an even layer about 1/8-inch thick. 
  • Add chocolate and let rest for 3 minutes. Using an offset spatula, gently spread the over top. Sprinkle on nuts and sea salt.
  • Chill until set, about an hour. Break into pieces.

Notes

-My microwave is 1000 watts. If yours is lower, you may need to cook it for slightly longer (1-2 minutes). If yours is higher you may need to cook it for a minute less.
-I would not recommend doubling the batch, but instead making two separate batches.

    I love that you can make this recipe in the microwave! So simple and delicious. Turns out every single time!

  2. Hi Natalie,
    I tried your recipe last night and have a quick question for you. I followed your recipe as written but when I poured the hot toffee on to my prepared pan, I noticed most of the butter had separated from the sugar mixture. Would you know why this happened? Is 1 cup of butter (2 sticks) the correct amount? Also, after 3 minutes, adding nuts, do we cook for 8-10 additional minutes or does one cook for only seven to eight more minutes? Tossing away the large amount of butter, sugar, and nuts was painful. I would really like to try this again with success. Thank you for any suggestions.

    • There might be a couple things that can make that happen. One is the heat being too high & the ingredients are melting at the same rate or too much humidity in the kitchen can cause separation. Sorry you had to throw that away. If that happens again, you can try removing it half way through & stir it, then return to microwave. You can also try adding a tablespoon of water to it, to help it come together. 1 stick of butter is 2 sticks & yes, after adding nuts, microwave for 8-10 min. Hope that helps! Good luck!
