The good news is, you really don't need any dairy ingredients to make peanut brittle at all, so it's the perfect treat for vegans and anyone eating dairy-free. We can't say your dentist will necessarily agree with me on that one, though! 

Peanut brittle is also super fast to make, so it can be a great time-saving option if you have a long list of Christmas treats to bake up, and this recipe can even be made entirely in the microwave. What's not to love? Read the entire recipe thoroughly first, however, since once you get started, you won't be able to stop to check in again.


  • 1 1/2 cups dry-roasted peanuts
  • 1 cup sugar 
  • 1/2 cup light corn syrup 
  • Optional: pinch of salt
  • 1 tbsp. vegan margarine
  • 1 tsp. vanilla extract 
  • 1 tsp. baking soda

Steps to Make It

  1. Lightly grease a baking sheet so it's ready to go.

  2. In a large glass bowl, stir together the peanuts, sugar, light corn syrup and salt. Place the mixture in the microwave and microwave on high for 6-7 minutes, until bubbly.

  3. Stir in the vegan margarine and vanilla extract, and heat for another 2-3 minutes.

  4. Remove from microwave and quickly stir in the baking soda, just until it gets foamy. Immediately pour the mixture onto the lightly greased baking sheet.

  5. Allow your peanut brittle to cool (don't touch!) for about 15 minutes, until firm and set.

  6. Break your peanut brittle into pieces, and munch away!

  7. Store your homemade peanut brittle in a zip-lock bag or another air-tight container.
