This no-bake treat turns the famous peanut butter and chocolate combo into handy dessert bars that happen to be gluten-free. With just a few basic ingredients and minimal work time, you'll whip up these tempting snacks that'll disappear in no time.

I threw these together for a block party when I needed something quick that wouldn't make my kitchen hot. They vanished faster than anything else at the dessert table, and I've kept the ingredients stocked ever since for unexpected company.

  • Smooth peanut butter: Creates that velvety foundation and works way better than chunky versions for the right feel
  • Room temperature butter: Gives these that wonderful melt-away quality that makes them so addictive
  • Vanilla extract: Boosts the nutty taste with sweet aromatic flavor
  • Powdered sugar: Adds sweetness while building that perfect soft-yet-firm texture
  • Chocolate chips: Create the iconic top layer; pick dark or milk depending on what you like
  • Coconut oil: Makes the chocolate topping shiny and easy to slice without cracking

Making Delicious Buckeye Bars

Get Your Pan Ready:
Put parchment in a 9x9 dish with extra hanging over the sides so you can lift everything out later. This step makes sure your bars come out looking good.
Mix The Base:
Beat together peanut butter and soft butter until they're totally smooth. You want everything blended with no streaks left. This makes the creamy bottom layer.
Build Flavor And Texture:
Stir in vanilla first, then slowly add powdered sugar. Go bit by bit to avoid making a mess. You'll see the mix change from soft and creamy to more solid, eventually pulling away from the bowl sides.
Press Into Pan:
Push the peanut butter mix into your lined pan and flatten it all over. Use your fingers or a spoon back to make sure it's even and reaches every corner. Take your time here for the best-looking bars.
Make The Topping:
Melt your chocolate chips with coconut oil in short microwave bursts, stirring often so it doesn't burn. The oil helps make it shiny and keeps the chocolate from getting too hard in the fridge.
Put It Together:
Pour melted chocolate over your peanut butter layer and spread it out completely. Chill for about 2 hours until everything's firm enough to cut nicely.

Powdered sugar really is the key ingredient here. I once tried using regular granulated sugar instead and ended up with something too grainy and way too sweet. The fine powdered stuff not only mixes better with peanut butter, but it also creates that special dry-but-fudgy feel that makes real buckeyes so good.

Smart Measuring For Best Results

How these bars turn out really depends on getting the powdered sugar right. For best results, don't scoop directly from the bag—that packs it down too much. Instead, spoon it into your measuring cup and level it off with a knife. If you've got a kitchen scale, try for about 300 grams of powdered sugar and you'll get perfect bars every time.

Keeping Them Fresh And Planning Ahead

Keep your Buckeye Bars in a sealed container in the fridge where they'll stay good for up to three days. Want to make them way ahead? They freeze amazingly well. Just put them in a single layer in a freezer container with parchment between layers if you stack them. You can eat them frozen for a firmer snack or let them warm up in the fridge for about 30 minutes before serving.

The Ohio Legacy

These tasty bars come from the famous Buckeye candy, named after Ohio's state tree nut which they look like. The original candy is peanut butter balls partly covered in chocolate to look like the buckeye nut. This easier bar version keeps all the flavor but cuts down on the work. Making these at home connects you to a Midwest tradition passed through generations of Ohio families, especially during football season when you'll find these treats at practically every gathering.

Ways To Enjoy Them

These rich treats go great with cold milk or hot coffee. For a fancy dessert, try them with a scoop of vanilla ice cream and warm peanut butter drizzled on top. Cut them smaller for party platters, or wrap single bars in parchment paper for bake sales and gifts.

Frequently Asked Questions

→ How long will these bars last in the fridge?

Keep your bars fresh and satisfying by storing them in a sealed container in the fridge. They’re good for up to three days!

→ Can I use chunky peanut butter?

Yep, you can switch to crunchy peanut butter! Just know it’ll give the bars some texture, while creamy keeps it smooth.

→ Which chocolate works best?

Pick your favorite! Go for dark chocolate for a bolder taste, milk for sweetness, or semi-sweet for balance. It’s up to you!

→ Why add coconut oil to the chocolate?

It’s optional, but if you mix in a little coconut oil, the chocolate turns smoother and gets that nice shiny look once it sets.

Yield: 9 Servings (9 bars)

Dietary: Vegetarian, Gluten-Free

Ingredients

→ Chocolate Layer

01 2 tablespoons coconut oil (optional)
02 2 cups chocolate chips

→ Peanut Butter Layer

03 1 stick butter, softened
04 1 teaspoon vanilla extract
05 2 ½ cups powdered sugar (don’t pack it too tightly)
06 1 cup creamy peanut butter

Instructions

Step 01

Grab some parchment paper and cover the bottom of a 9x9 dish.

Step 02

Put the softened butter and creamy peanut butter in a stand mixer bowl. Mix on medium speed until smooth, scraping the sides as needed.

Step 03

On low speed, mix in the vanilla extract. Slowly sprinkle in the powdered sugar, and let it blend until a dough forms. If it's too sticky, add powdered sugar little by little.

Step 04

Scoop out the peanut butter dough and spread it evenly into the pan. Use clean fingers or the back of a spoon to press it firmly into place.

Step 05

In a microwaveable bowl, combine chocolate chips and coconut oil. Heat for 30 seconds, stir it up, then microwave another 20-30 seconds until melted and smooth.

Step 06

Pour the melted chocolate over the peanut butter layer. Use a spatula to spread it out so it’s nice and even.

Step 07

Put the dish in the fridge for about 2 hours so the chocolate sets and becomes solid.

Step 08

Add a sprinkle of sea salt on top before serving if you want.

Notes

  1. Keep the bars in a sealed container in the fridge for up to three days.
  2. Adding the coconut oil makes the chocolate texture smoother and gives it a nice shine.
  3. For the best results, weigh your powdered sugar or measure it properly to keep the bars from crumbling.
