Grandma’s Peanut Brittle Recipe

Grandma's Peanut Brittle Recipe

My Grandma Wanda was the queen of Christmas candy. Some of my favorite childhood memories are of her kitchen counter filled with all kinds of homemade Christmas candies packed in a a variety of Christmas tins. From toffee to divinity, she even had an amazing hard cinnamon candy and I haven’t seen a recipe similar to it anywhere else. My aunt was kind enough to send me pictures of some of her handwritten recipes so I can share them with my kids and with my friends here on the blog. Grandma Wanda’s peanut brittle is very easy to make and perfect for homemade Christmas gifting.

For this recipe, you’ll need a candy thermometer (I like the kind that clip to the side of the pot), a large heavy bottomed pot and a buttered sheet pan.

  1. I made the Peanut Brittle over the weekend and it was like I was stepping back in time to when I was a child in my own Grandmother’s kitchen. Thank you so much for posting this recipe. My Grandmother’s recipes have mostly been lost, but this is exactly like her brittle.
