Chocolate Peanut Butter Oatmeal Bars

These Chocolate Peanut Butter Oatmeal Bars are loaded with a creamy filling and studded with chocolate chips. They’re rich, decadent and oh-so-yummy!

I love everything about these bars. The creamy filling, the rich chocolate chips, the buttery oatmeal bottom and top layers….it’s just a whole lotta good in one bar!!

I tested this recipe so many times. I started with my chocolate revel bars recipe then tested different ratios of flour and oatmeal, different fillings, and a handful of different baking temperatures/times.

Honestly, it got to the point where my husband said “are you just testing these again because you wanna eat them??” Busted. Ha! But lucky for you, this recipe for Chocolate Peanut Butter Bars with sweetened condensed milk is done and ready to share!

Ingredients Needed

• Butter – I use salted butter; you’ll need this for the cookie base and for the filling
• Sugars – You need white and brown sugar (light or dark brown sugar is great)
• Eggs – I use “large” eggs in my recipes
• Vanilla Extract
• Creamy Peanut Butter – I don’t recommend the “natural” peanut butter as it may affect the consistency
• All-Purpose Flour
• Quick Oats – aka Instant Oats (uncooked)
• Chocolate Chips – I use semi-sweet to balance the sweetness
• Sweetened Condensed Milk – Do NOT confuse this with evaporated milk (they’re VERY different!)
• Peanut Butter Chips – Reese’s brand peanut butter chips are my favorite

How do you make Chocolate Peanut Butter Oatmeal Bars?

First, you’ll want to prepare a pan by lining it with parchment paper, foil or spraying with cooking oil. Then, preheat the oven to 350 F and get ready to bake!

Then, you’ll add butter (room temp), creamy peanut butter, sugar and packed brown sugar to a mixing bowl. Once it’s light and fluffy, add the eggs and vanilla. Finally, you’ll stir in the quick oats and flour until combined.

Press 2/3 of the mixture into the prepared pan and bake. While it’s baking, you will prepare the filling by microwaving peanut butter chips, sweetened condensed milk and butter and stirring until smooth.

Next, spread the peanut butter filling over the oatmeal crust, sprinkle with chocolate chips and break up the remaining oatmeal mixture to place on top.

The bars will then go back into the oven to finish baking. Bake for 20 minutes or until the edges are beginning to brown. Once you’ve removed them from the oven, let cool completely, cut into bars and devour!!!

How should I store leftovers?

Cover the bars with a lid or aluminum foil. They’ll stay good on at room temperature or you can keep them in the fridge. Eat or freeze within 5 days.

Can I freeze Chocolate Peanut Butter Oatmeal Bars?

If you’re lucky enough to have leftovers, you certainly can freeze them! I like to cut them into squares, place into freezer bars and freeze for up to 3 months.

When you’re ready to eat, just grab one (or two!), let it thaw at room temperature and enjoy! Or, if you’re super impatient, like me, put it in the microwave for a few seconds to soften it up! 🙂

Can I make these Gluten Free?

YES! Use a “cup for cup” gluten free flour in place of the all purpose flour. You’ll also want to make sure the oats you’re using are made in a facility without wheat. Double-check the remaining ingredients, and you should be good! 🙂
