Toffee RECIPE For Amateurs (Like Me!)

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 recipe.

You heard that right. It’s made in the microwave. Forget having to boil in a pan on the stovetop to find the hard crack stage! This homemade Toffee Recipe is made in a big bowl and then poured onto a silicone baking mat. Toasted pecans and flaky sea salt make it extra amazing!

We devour this toffee every time we make it. It’s perfect for holiday dessert trays, Christmas 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!

Toffee Recipe Ingredient Tips

Just a few things to keep in mind for the ingredients…

  • Corn Syrup:Dark corn syrup has a richer flavor because it includes molasses, light corn syrup doesn’t have as rich of a flavor. For this recipe you can do either types of corn syrup, but if you’re worried about the molasses taste being too overpowering I would recommend using light corn syrup.
  • Chocolate: We recommend using chocolate chips for this recipe. In terms of what type of chocolate you can choose between milk, semi-sweet, bitter-sweet, or white. We love using the Ghirardelli chocolate brand, but you can always use your store brand of chocolate chips.
  • Nuts: 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 macadamia nuts).

How to Make Microwave Toffee

It took me three painstaking tries to get this toffee 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.

LINE a baking sheet with silicone baking mat or parchment paper, set aside.

COMBINE. Grab a large glass microwave-safe bowl, combine the butter, sugars, salt, corn syrup, and water.

MICROWAVE. Microwave for 3 minutes on HIGH. Stir in toasted chopped pecans or stir and keep it plain. Microwave for an additional 8-10 minutes on HIGH or until it reaches 300 degrees F on an instant read or candy thermometer – pause the microwave cooking every 2 minutes and stir and check the temperature – do NOT overcook it, or it will burn.

SPREAD. Pour mixture onto the prepared baking sheet and spread into an even layer.

TOPPING. Add the chocolate chips on top, let them melt then spread the melted chocolate over top. Sprinkle on nuts and sea salt.

SET. Chill until set, then break into pieces.

Storing Your Toffee

STORE the leftover toffee at room temperature in an airtight container. You definitely want to keep the toffee in a cool and dry place so it doesn’t get sticky. If it is really warm in your house, you can keep it in the fridge. When stored at room temperature it will last for about 2 weeks. If you keep it in the fridge it will keep for a bit longer.

You can also FREEZE pieces of toffee for up to 6 months in an airtight container.

  • Microwave for 3 minutes on HIGH.

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.

FAQs

Why is my toffee chewy and not crunchy? ›

Low and slow

Simmering the syrup for English toffee to the requisite 300°F temperature can (and should) be a slow process — up to 20 minutes or so. Don't hurry this gradual transformation; syrup that doesn't reach 300°F, or close to it, will make candy with timid flavor and chewy (not crunchy) texture.

Why won t my toffee get hard? ›

If your toffee doesn't have a hard texture (where you can snap it in half) you did not cook it long enough. Again, the 5-minutes is just a guide. Cook it until it is the color of a brown bag.

How do you know when toffee is ready? ›

Once boiling, cook, stirring only 2 to 3 times, until it turns a dark amber color and the temperature reaches 285 degrees F (137 degrees C) on a candy thermometer, 20 to 30 minutes. Immediately pour toffee into the prepared baking dish. Sprinkle chocolate chips on top and let sit until they soften, 1 to 2 minutes.

Why do you put baking soda in toffee? ›

You might wonder why the toffee recipe includes baking soda. It is added at the end of the boiling stage and creates lots and lots of bubbles. These bubbles help to lighten the texture of the finished toffee, resulting in an easier-to-bite candy.

What can go wrong when making toffee? ›

Stirring too quickly or too often can cause the toffee to separate. Moderate the heat as needed – turn it down if the toffee is boiling or cooking too fast so it doesn't burn. Cook until the toffee registers 285-290 degrees on an instant-read or candy thermometer and is deep amber brown in color, about 20-25 minutes.

How do you keep butter and sugar from separating when making toffee? ›

Rub the cube of butter around the sides of the pan before adding sugar. This will help keep sugar crystals from clinging to the sides. When adding the sugar, place it in the center of the pan to keep sugar crystals off the pan sides. During cooking, occasionally wash the sides of the pan with a brush dipped in water.

Should I stir while making toffee? ›

Continue to stir occasionally, the mixture will slowly thicken and will turn a more yellow hue as it cooks, and cook to hard crack (305°F/151°C). Once toffee reaches 305°F/151°C, immediately remove from heat and stir in vanilla extract (careful, it bubbles and steams a bit).

What to do if toffee doesn t set? ›

It's a treacle toffee, family recipe! Thanks! put it back in the saucepan and reheat it. It usually means it didn't get hot enought the first time.

What happens if you cook toffee too long? ›

Toffee Making Tips + Troubleshooting

Your toffee is better off overcooked than undercooked! Undercooked toffee won't be anything more than a caramel sauce. But overcooked toffee will be just slightly crunchier (almost unrecognizably). So, always err on the side of over-cooking!

Why is my toffee not set and why is it's texture grainy and not smooth? ›

As the toffee cools and the molten sugar crystals become solid again, they are attracted to the 'seed' forming new lumps of tiny crystals – hence the grainy texture. This can also happen if the toffee is stirred, or agitated, after it has begun to boil or on cooling (as happened with this pink-tinted toffee).

Why is my cracker toffee chewy? ›

Then, make sure the entire mixture comes to a rolling boil, not just the edges of the pan. Why is my saltine toffee chewy? If your saltine toffee, or Christmas crack, is chewy, it's because the chocolate hasn't fully set yet. Try popping it in the fridge for 15 minutes to firm it up.

What texture should toffee be? ›

Ideally toffee has a nice snap when you bite into it, but then it gives way to a tender texture that immedietly crumbles and dissolves in your mouth. Even though I add a tremendous amount of butter to my recipe, the texture I end up with is more like a hard candy that ultimately sticks to your teeth.

Should toffee be hard or soft? ›

Toffee is a hard candy made by cooking a sugar syrup with butter to the hard crack stage, 300–310°F (149–154°C), and then pouring it out to cool. It can have inclusions or not, and it can be made either very dense and hard or can be lightened by adding baking soda when the candy is almost done cooking .
