Calling all peanut butter lovers!
Today I’m so excited to be sharing the most yummy peanut butter oatmeal bars recipe with you that are simply the perfect choice to make whenever you’re craving a peanut butter dessert.
My Triple Peanut Butter Oatmeal Bars are thick, soft, chewy, and absolutely delicious! And with triple the peanut butter flavor, you won’t be able to resist eating one.
Even better, my chewy peanut butter oatmeal bars are made with simple, everyday ingredients you probably already have in your pantry and can be made in less than 30 minutes time.
I highly recommend using parchment paper since this makes it easy to lift the bars out of the pan and makes it mess-free when cutting the bars.
Make sure you press the bars into all four corners of the pan.
Next you’re going to create your peanut butter streusel using brown sugar, flour, peanut butter, and butter.
Mix together until a crumbly consistency forms, then sprinkle evenly on top of the peanut butter oatmeal bars.
Place the bars in a 350 degree F preheated oven and bake for 25-28 minutes, or until the bars are lightly golden.
While the bars are baking, whisk together your peanut butter drizzle in a bowl by combining powdered sugar, peanut butter, and milk.
Although the recipe calls for 1-3 tbsp of milk, you may have to add more or less milk depending on the weather and other variables.
I recommend adding 1/2 tbsp at a time, whisk together, and continue adding as needed until a light drizzle is reached.
Once the bars are fully cooked, remove from the oven and let cool for 15-30 minutes.
Once cooled, it’s time to add that yummy peanut butter drizzle on top.
You can use a spoon to drizzle it on, or to make it easier (and less messy) I prefer using an icing bag or Ziploc bag with the corner snipped off to drizzle it on.
Let the bars set for 10 minutes, then cut, and enjoy!
Tip: If you use parchment paper, you can easily lift your bars out of the pan and onto a cutting board for quick + easy cutting.
I mean, do these peanut butter oatmeal bars not look amazing?! Just look at all that peanut butter deliciousness!
I also love how the peanut butter drizzle make the peanut butter oatmeal squares look so pretty and decadent, and trust me when I say your family and friends will absolutely LOVE these baked peanut butter oatmeal bars.
In a small mixing bowl, combine the flour, brown sugar, peanut butter, and softened butter to make the streusel. Mix until a crumbly consistency is reached, but do not overmix. Sprinkle evenly over top the peanut butter oatmeal bars batter.
Bake at 350 degrees for 25-28 minutes until bars are lightly golden.
Remove bars from oven and let cool for 15-30 minutes before adding the peanut butter drizzle over the bars.
Peanut Butter Drizzle
While the peanut butter oatmeal bars are baking, use a whisk and combine powdered sugar, peanut butter, and milk in a small bowl. Add milk in 1/2 tbsp at a time until a drizzling consistency is reached. Place in the fridge until ready to use.
For an easy mess-free drizzle, place peanut butter drizzle in a decorator’s bag or Ziploc bag with the corner snipped off, and drizzle as desired.
Let bars set for 10 minutes before cutting, then serve and enjoy!
Store remaining peanut butter oatmeal bars in an airtight container at room temperature for up to 5 days.
