I got this recipe from my friend Melissa. It's made in the microwave and I think the cleanup was fairly easy compared to making it on the stove top. It tastes just as good too. The nuts will get slightly toasted in the microwave, so the flavor is spot on.
I've also made batches adding a little bit of chipotle chile powder or cinnamon. Either of those spices work well.
1 c granulated sugar
1/2 c light corn syrup
1 cup dry roasted peanuts
1 tsp vanilla
1 tsp butter
1 tsp baking soda
Combine 1 cup granulated sugar with 1/2 cup light corn syrup and microwave on high for 3-4 minutes.
Add 1 cup of nuts, mix (although it'll be super hard to mix well), and microwave for 2 minutes. If your microwave is strong, keep an eye on it to make sure the nuts don't scorch.
Add 1 tsp vanilla and 1 tsp butter, mix and microwave 2 minutes.
Add 1 tsp of baking soda and stir well. It gets all foamy at this point but just stir until it settles down.
Spread immediately onto parchment paper, flattening with a spatula or knife to about 1/2 inch thickness. Let cool completely and then break up to serve.
