These easy bar cookies are an old fashioned treat.
I have tried every way I can think of to research the beginnings of Hoosier Peanut Bars.
The name sounds like something from the 1930s and I found out that a version of the bar cookies were entered into the Pillsbury Bake-Off in 1949 by Edgar Bleeke of Fort Wayne, Indiana. He won, by the way.
My version is based on a recipe from a 1950's cookbook put out by the Federation of Women's Clubs, whoever that was.
It is a collection of recipes from all over the country and is truly falling apart on me. I love these old cookbooks.
The recipes change from decade to decade and you can see how America's tastes have changed. I would love to say that they have evolved but in most cases that wouldn't be true.
When you make these- because most certainly you will - appreciate the difficulty that someone endured to make it possible for you to enjoy peanuts.
In my research I came across several comments about people not being able to get the meringue to stiffen up and stand in peaks. I even read one site where the writer shrugged it off and said not to worry about it.
Worry about it. There is no reason you can't get the meringue right if you follow a few simple tips:
- Try to make these on a dry day. The less humidity the better.
- Always use egg whites at room temperature.
- Egg whites can't have even a molecule of fat or they won't whip. No greasy residue on bowls or kitchen tools, no oils from fingers, no spot of egg yolk no matter how small.
- Rinse the clean mixer bowl and beaters with vinegar just before making the meringue. Do not rinse the vinegar out ... just dump out the excess. The acid helps the meringues hold up.
- Whip the egg whites until they are foamy and translucent before you start to add sugar.
- Add the sugar slowly. I timed this - it took me ten minutes to use up the sugar a tablespoon at a time. Whip well after every addition.
- Check that the sugar is completely dissolved by rubbing a little of the meringue between your finger and thumb.
I also use both Tahitian and Bourbon vanillas in this recipe because the combination gives a nice depth of flavor.
Follow the steps exactly and I think you will find that this recipe is easy, and soon becomes a favorite.

I just made these. My grandma used to make them all the time. I used your recipe because my grandma's did have the oven temp or time. However, I think you butter amount is incorrect. My sugar butter mixture was by no means creamy, more like lumpy sugar. Everything else turned out great but the bottom is just kind of mush.

I'll try to remake it soon to check but it's the recipe I've always used successfully

My mother made these all the time back in the early 1950's when us kids were growing up in Illinois., very close to Indiana. She gave me the recipe some years ago, but I misplaced it. Thank goodness for "google"! I had totally forgotten about the meringue part. I can't wait to make them. Good memories!

Low humidity huh....I may have to wait to make these in the winter then since I live in Georgia where summer is a wet blanket of heat and humidity. I'm pretty sure it's like that for you in TX too. 🙂

If you have the air conditioning on under 80F it dries it out enough for it to work.
