Grandpa’s Peanut Brittle

My Grandpa Bill passed away several years ago, but I always think of him at Christmas time while I’m fixing his favorite candy – peanut brittle.


Here he is with his sweet wife, my lovely grandmother, Bea.  As a child I remember my mom always making peanut brittle for Grandpa each Christmas.  Now it simply doesn’t feel like Christmastime if I don’t make up a batch of Grandpa’s Peanut Brittle.

I really love this recipe because it works every time . . . plus, you make it in the microwave.  How easy is that?


1 cup sugar
1/2 cup light corn syrup
1 cup dry roasted peanuts
1/8 tsp. salt
1 tsp. butter
1 tsp. vanilla
1 tsp. baking soda

Here’s what you do

1.  In a 1 1/2 quart microwave-safe bowl, stir together the sugar, syrup, peanuts, and salt, mixing well. Microwave on high for 4 minutes.
2.  Carefully swirl the butter and vanilla into the mixture (do not stir). Microwave another 30 seconds.
3.  Add baking soda and gently stir the mixture until it’s light and foamy. Pour it on a lightly buttered cookie sheet.


*Tip: For thinner brittle, warm the cookie sheet in the oven first.
Let the brittle cool for 30 minutes to an hour, then break it into pieces.

The only thing I have to watch is that the first mixture doesn’t burn when I microwave it.  It’s an old recipe, from back when microwaves were much weaker.  The recipe used to read “6 minutes,” but I’ve changed it to “4 minutes” for my microwave (which is new and cooks really hot and fast).  You can adjust the timing between 4 and 6 minutes.  If it starts to burn you’ll smell it immediately and can probably stop it in time.  It should have a great boil on it though.

Hope you enjoy this old family favorite and visit our recipes page for more yummy family recipes of ours.  And I hope there’s peanut brittle in heaven.  Merry Christmas Grandpa!
