Peanut brittle is a treat we’ve been enjoying since we were little in Stillwater, MN as we would walk around the town by the St. Croix river enjoying the scenery, but more importantly, the local candy store.
There are not a lot of steps to make this peanut brittle, but it does require a little patience. To start, bring sugar, water, corn syrup, and salt to a boil. Once it starts to boil and the sugar has dissolved, stir in the peanuts. Now comes the patience part. Stir the mixture frequently until it turns amber in color and reaches 300 degrees on a candy thermometer. This process will probably take about 10-13 minutes.

All that’s left is to add butter and baking soda to the mixture off the heat and then pour onto a greased baking sheet. We used a silicon baking mat because it makes clean up really easy. You’ll have to work quickly and spread the mixture evenly before it starts to set. Then just let it cool and break into pieces.
