My microwave pecan brittle is a quick and easy take on the classic. Using the microwave, you can create crunchy brittle with that classic, bright, sweet flavor and an extra note of earthiness thanks to chopped pecans.

I love making brittle for the holidays. It’s an easy recipe that can be made relatively quickly, and that’s always a big plus for special occasions!
I love making classics like peanut brittle or variations like chocolate cashew brittle to keep things interesting. Now, I’ve added a new twist with my pecan brittle.
This brittle uses a classic base of sugar and corn syrup to create that sweet flavor and glassy, crackable texture. However, the addition of pecans gives it a darker, more robust flavor with earthy notes that is soooo good.

Pecan Brittle FAQS
Brittle is hard and crunchy, cooked to the “hard crack” stage, and uses corn syrup for crispness. Praline, on the other hand, is softer and creamier, made with cream, butter, and brown sugar, and cooked to the “soft ball” stage.
If you’re making brittle in the traditional way, use a candy thermometer. When the mixture reaches between 300 and 310°F, it’s ready. If you’re using the microwave method, the mixture should turn a golden color before you spread it out to cool.
Any nut can be used for brittle. Peanuts, almonds, and pecans are all classic choices. However, varieties like cashews, macadamias, hazelnuts, and even pistachios work, as well. Try your favorites!
Pecan brittle will last for up to 2 weeks at room temperature in an airtight container. You can also freeze it for up to 3 months in an airtight, freezer-safe container.
