Why Make Homemade Candy

Think making candy at home is too difficult? Think again!

  • Best testing candy – This sweet and salty cashew brittle tastes so much better than any brittle candy you can buy at the store.
  • Stays crunchy for weeks – Like our Peanut Brittle Recipe, this one won’t lose its crunch when you store it.
  • As easy as can be – It’s made with a handful of ingredients you probably already have on hand!
  • No special equipment needed- If you have a bowl and a microwave, you can make homemade cashew brittle. You don’t need a candy thermometer or even a stove!
  • A perfect gift ideaEveryone loves receiving a bag full of homemade candy, especially when it tastes as good as this one.

Whether you’re a candy making expert or total novice, this Cashew Brittle recipe is for you. It’s beautifully crunchy with a sweet and salty cashew toffee flavor.

Ingredient Notes

  • Granulated sugar and corn syrup – The sugar dissolves and crystalizes in the corn syrup when heated to form a candy base that doesn’t get grainy.
  • Cashews – We recommend roasted salted cashews, chopped into bite sized pieces. Or swap it out for your favorite nuts!
  • Baking soda – Adds air buttles to the candy for a lighter, crispier texture.
  • Vanilla extract – We love using homemade vanilla extract or another good quality pure vanilla extract.

Recipe FAQs

Can I use other kinds of nuts in this recipe?

You sure can! Feel free to use pecans, almonds or any other lightly salted nut you like.

How long does it stay good?

Stored in an airtight container, this cashew brittle stays crunchy and delicious for about one week. But it never lasts that long at my house because my family and I can’t resist eating it!

Why did my cashew candy mixture burn?

This candy will burn if your microwave is too hot or you heat it for too long. I used power level 7 (out of 10) on my 1500 watt microwave.

I don’t have a microwave. Can I still make this recipe?

Yes, it cane be made on the stove with a few adjustments. See my peanut brittle recipe for instructions to make this on your stove top!

  12. I don’t have the ability to change the cooking power on my old microwave and my first batch ended up a burnt mess! I cut the cooking times in 1/2 and it worked perfectly!

    Warning: Do not put the hot glass bowl in cold running water – my grandmother’s glass pryrex bowl broke into pieces when I put it in the sink and turned the water on. Lesson learned. That bowl was HOT, as you said it would be!

    End result: AWESOME Cashew brittle. #burnedbrittlesmellsgross, #brokegrandma’sglassbowl, #2ndtimeisacharm.

FAQs

Why add baking soda to brittle? ›

Baking soda also raises the pH of the mixture, promoting the Maillard reaction and giving the brittle its particular color and flavor profile.

Why isn't my peanut brittle hard? ›

The main reason why peanut brittle doesn't get hard and have the crunch we expect is because the sugar was not cooked long enough. The sugar needs to be cooked to what is called the hard crack stage, 300ºF.

What is cashew brittle made of? ›

It's just cashews, butter, sugar, corn syrup, baking soda, and the aforementioned sea salt. It's adapted from a recipe in Karen DeMasco's wonderful book, The Craft of Baking. What is this? The only equipment you need is a pot, a rimmed baking sheet, and an inexpensive candy thermometer.

How long do I need to soak cashews? ›

Because cashews don't have a thick outer skin and they already start as a softer nut, they only need to be soaked for about 2-3 hours. You can soak them overnight, just be sure to place them in the fridge. Over soaking them can lead to bitterness, slimy water, and leaching of their flavor.

What makes things crispy baking soda or baking powder? ›

Baking powder is better for recipes that contain little or no acid ingredients. Baking soda helps make fried foods crispy and light. It is also useful for cleaning and removing stains.

What happens to baked goods when you use too much baking soda? ›

It's important not to use too much baking soda in recipes, as it can result in a metallic, soapy flavor. It is much more powerful than baking powder – you only need about 1/4 teaspoon baking soda per cup of flour to leaven baked goods.

What makes brittle hard? ›

What Makes it Brittle? The sugar will be cooked to 300ºF (149ºC)—hard crack stage; which when set up would be hard like a lollipop. But peanut brittle is delicate and you can easily bite into it—how? The secret is in the baking soda.

How long does it take for brittle to harden? ›

Carefully pour the hot mixture onto the prepared pan and use a knife or spoon to quickly (and carefully!) spread the mixture into an even layer. Allow to cool completely (at least 30 minute) before breaking apart and eating. Store the completely cooled peanut brittle in an airtight container.

Why is my peanut brittle hard but sticky? ›

What's important to know is that the corn syrup controls the grain of the brittle so adding too little and you have a grainy textured brittle, while adding too much will result in a stringy and sticky brittle.

Why can't you bite a raw cashew? ›

Raw cashews contain urushiol, a resin that is toxic if ingested and can cause rashes or burns if it contacts the skin. To remove this substance, cashews must go through a rigorous roasting or steaming process to ensure they are safe to eat. This is why you will always see cashews shelled at the grocery store.

What is the black mold in cashews? ›

Black mould is one of the most important foliar diseases of dwarf cashew plants in coastal zone of northeastern Brazil.

Why do you soak cashews in water? ›

Soaking cashews is just submerging them in water and allowing them to absorb the water. in order to soften them for blending. Your results will be creamier. silkier and smoother.

Why are cashews so expensive? ›

Roasting the cashew nuts to destroy the toxins is dangerous as well, as the toxins are released into the air. After the toxins are removed, the cashews must be graded and sorted. The entire process is labor-intensive as well as hazardous, which helps explain part of why cashews are so expensive.

What happens if you don't soak cashews? ›

In addition to phytic acid, cashews also contain a large number of enzyme inhibitors. When too many of these inhibitors are present, it can make the nut hard to digest. Soaking is a way to neutralize some of these enzymes, allowing for proper digestion when you eat the cashews.

Why do cashews turn purple when soaked? ›

The soaking cashews will swell, especially the ones that sit overnight. However, if they have turned purple-ish it is a sign they have soaked too long and you should start over.

How do you keep peanut brittle from getting sticky? ›

Store in an airtight container or a plastic freezer bag as this will prevent the brittle from becoming sticky and breaking down. Store at room temperature or in the refrigerator for up to two weeks.

What does baking soda do in candy making? ›

The soda reacts with the acid to make bubbles, and the syrup foams. When the cooked syrup is poured out and begins to harden, many of the tiny bubbles are trapped before they can escape (another reason the baking soda is added at the end).

Why do you add baking soda to dough? ›

Baking soda becomes activated when it's combined with both an acidic ingredient and a liquid. Upon activation, carbon dioxide is produced, which allows baked goods to rise and become light and fluffy (1).
