Vegan Peanut Brittle

The mix of salty peanuts and rich caramel combine to create this crunchy, hard toffee that’s a classic favourite. This recipe makes an excellent gift or a sweet treat to be shared.

I was sitting on the bed last night eating a piece of vegan fudge (recipe coming soon!) which reminded me I made this vegan Peanut Brittle months ago and hadn’t posted the recipe yet. Quite a surprise really as the Peanut Brittle was so good when I made it, I made multiple batches over the coming weeks.

This recipe is made much simpler if you have a candy thermometer. Relatively inexpensive and start at around $10. My cheapie has gone strong for many years, multiple house moves and plenty of peanut brittle batches. I do recommend using one when making this recipe to eliminate guesswork.

Recipe Tips

Following a few simple steps will help you achieve the perfect crunch for your Peanut Brittle.

  1. Use very clean equipment. I re-wash and dry my saucepan and spoon/ spatula prior to making the brittle. Any little left-behinds on the tools can cause a reaction.
  2. Don’t over mix the sugar, glucose and water as this will cause crystalisation. Mix the ingredients together and leave to boil until the right temperature is achieved. During the cooking process any sugar syrup can be removed by brushing the side of the pot with water on a pastry brush.
  3. Don’t stir the sugar in the first step. Allow it to boil until reaching the required temperature.
  4. Cool completely prior to breaking into bite-sized pieces.

Peanut Brittle will store at room temperature in an air-tight container for up to two weeks and in the freezer for two months. But seriously, this recipe doesn’t need storage instructions – it won’t last long!
