No Bake Peanut Butter Oatmeal Bars Recipe For When You Need an Easy Treat

July 3, 2022 by Faith 2 Comments

Jump to Recipe

No Bake Peanut Butter Oatmeal Bars have a crunchy, buttery brown sugar oatmeal top and bottom with a fudgy peanut butter filling. They’re easy to make and whip up in just 20 minutes!

When it’s hot outside, I avoid turning on the oven at all costs. Here in Florida we have central air conditioning, but the oven still heats up the entire kitchen and living area, and then it takes hours for the house to cool down.

It’s just easier to make a dessert that doesn’t require oven time, lol.

I’ve been making Chocolate Oatmeal Bars for years, and No Bake Peanut Butter Oatmeal Bars is a spin off that. Here instead of a fudgy chocolate filling, we use a blend of white chocolate and peanut butter. These bars have the same fudgy texture, but they aren’t so overwhelmingly chocolate-flavored.

Of course a little drizzle of dark chocolate on top pairs well with the peanut butter filling. And just a sprinkling of sea salt balances everything.

These no bake bars go beyond a good dessert for summertime gatherings. They’re quick and easy to make and always a crowd-pleaser. Whip them up for your next party!

Ingredients

Top and Bottom Oat Mixture:

  • Unsalted butter
  • Light brown sugar
  • Salt
  • Old-fashioned rolled oats
  • Pure vanilla extract

Peanut Butter Filling:

  • White chocolate chips
  • Creamy peanut butter

Toppings:

  • Semi-sweet chocolate chips
  • Flaky sea salt

Step-by-Step Instructions

Step 1: Toast the Oats for the Top and Bottom:

toasting oats

Add the butter, brown sugar, and salt to a medium saucepan over medium heat. Cook until the butter is melted, stirring occasionally. Stir in the oats and vanilla and cook until the oats are toasted, about 2 to 3 minutes, stirring occasionally.

Storage

Store leftovers in an airtight container in the fridge for up to 5 days.

Tips

  • These bars have a more solid consistency straight from the fridge. If you let them sit at room temperature for 15 minutes, they have a fudgy consistency. Don’t leave them outside in the heat because they will melt.
  • For a chocolate filling instead, mix together 1 cup of semi-sweet chocolate chips + 1/2 cup of heavy whipping cream.

How Do You Freeze Oatmeal Bars?

Once these are cut into squares, arrange them in layers between pieces of parchment paper in an airtight container. Freeze them for up to 3 months, and thaw in the fridge overnight before eating.

How Can I Make These Into Chocolate Oatmeal Bars?

If you’re looking for a fudgy chocolate oatmeal bar, this recipe is perfect. All you need to do is swap out the filling!

Instead of using white chocolate chips and peanut butter, use 1 cup of semi-sweet chocolate chips + 1/2 cup heavy whipping cream. Melt it together and proceed with the recipe.
