Mexican Candy: Spicy Peanut Brittle


This recipe for spicy peanut brittle uses simple ingredients and it only takes 25 minutes to make, start to finish!

  • Granulated white sugar
  • Piloncillo or brown sugar
  • Honey
  • Kosher salt
  • Chili powder (I suggest using my homemade chili powder recipe)
  • Butter – If you use salted peanuts, it’s best to use unsalted butter
  • Toasted peanuts

If you prefer a less spicy brittle, you can substitute ground cinnamon for the chili powder. 🙂

What is piloncillo?

Piloncillo is a raw cane sugar with a taste similar to molasses. It is easy to find at many Mexican/Latino markets.

The equivalent of what Americans call brown sugar, piloncillo (also known as panela) has a natural rich flavor.

The most common use for it is in South American recipes, especially desserts and candy.

Tips when working with hot sugar

Making Mexican candy is a lot of fun. However, you have to be very careful when working with hot sugar, especially if it’s not something you do often.

Sugar burns easily, especially if you don’t watch the temperature. Plus, it can splatter, causing serious burns to exposed skin. Here are a few tips to keep things safe and easy:

  1. Keep cold water handy in case of an emergency. If you get any hot sugar on your skin, submerge the affected area in cold water immediately.
  2. If at all possible, use a candy thermometer. Temperature is very important when working with hot sugar. As a result, a proper candy thermometer will make it easier to monitor the sugar as it cooks.
  3. Do not walk away! Sugar can burn in a split second, so this is one time you need to watch the pot constantly.
  4. Use minimal stirring. Don’t stir the sugar after it starts to heat up. Too much movement can cause it to crystallize on the inside of the pan.

Other examples of traditional Mexican candy

Mexican candy and other sweet treats come in a range of flavors. There are sweet candies, salty or spicy, and sometimes all three at the same time!

Some popular traditional Mexican sweets include:

  • Tamarind-flavored candy: This popular flavor is available in a variety of candies. Mexican favorites include Pulparindos, Tamarindos, and tamarind-laden spoons. The spoons feature tamarind flavored chewy candy paste that is scooped into white plastic spoons.
  • Chocolate: Mexican chocolate is often flavored with spices, like chili peppers and cinnamon.
  • Alegría: A sweet treat made with a mixture of honey and amaranth seeds.
  • Mexican mazipan: Similar to marzipan (which is made with almonds), mazapan is usually made with ground peanuts mixed with sugar, made into a stiff dough and then cut into pieces.
  • Dulce de leche: Made from sugar and burnt milk, this is a often made into a thick, soft chewy candy.

Of course, this is just the tip of the iceberg! There are plenty of Mexican treats, cookies and other desserts to try. Here are a few of my other sweet Mexican recipes to get your started:

  1. looks so good. tried a garlic chilli peanut butter brittle at the Ottawa Market a few years ago. I think they used Rooster Brand Garlic Chilli Sauce. Anyhow, it was awesome.
