Homemade Microwave Cashew Brittle Ingredients
- 1 cup cashews (whole or halves)
- 1 cup granulated sugar
- ½ cup light corn syrup
- ⅛ teaspoon salt
- 1 tablespoon real butter
- 1 teaspoon baking soda
- 1 teaspoon pure vanilla extract
How to Make Cashew Brittle in the Microwave
Step 1: Mix and Cook the Base
- In a medium microwave-safe dish, combine sugar, light corn syrup, and salt.
- Microwave on high for 3 minutes.
- Stir the mixture and microwave for another 2 minutes and 45 seconds.
Tip: Microwaves vary, so keep a close eye to prevent burning.
Step 2: Add Butter and Cook Again
- Stir in 1 tablespoon of real butter and mix well.
- Microwave for another 2 minutes and 45 seconds.
Step 3: Add Baking Soda and Vanilla
- Stir in baking soda and vanilla extract. The mixture will foam up—this is what creates the light, airy texture.
Step 4: Pour and Cool
- Immediately pour the mixture onto a well-greased cookie sheet.
- Use a sprayed spatula to spread it evenly.
- Let cool completely, then break into pieces.
Tips for the Best Microwave Cashew Brittle
- Use a heatproof spatula – The mixture gets extremely hot, so avoid plastic utensils that may melt.
- Work quickly – Once you add the baking soda and vanilla, brittle starts setting fast.
- Spray your spatula and pan well – This prevents sticking and makes spreading the brittle easier.
- Adjust cooking times – Microwaves differ, so check frequently to avoid burning.
Can I Use Other Nuts for This Brittle Recipe?
Absolutely! You can swap cashews for:
- Peanuts – Classic peanut brittle
- Almonds – For a nutty, caramelized crunch
- Pecans – A Southern twist on brittle
You can also mix different nuts for a unique combination.
How to Store Homemade Cashew Brittle
- Room Temperature: Store brittle in an airtight container for up to two weeks.
- Avoid Humidity: Brittle can become sticky if exposed to moisture.
- Freeze for Longer Storage: Store in a sealed bag in the freezer for up to three months.
