Sheet pan chocolate peanut butter oatmeal cookie bars are simple to whip up, incredibly yummy, and can easily feed a crowd. In addition, these easy no-bake cookies are a total fan favorite!
I have a major thing for cookie bars. I love the simplicity of a great cookie bar. Sometimes, you just don’t want to scoop out two dozen cookie balls, one by one. And trust me, when it comes to cookies, especially great cookies like these campy chocolate peanut butter oatmeal cookies, no one cares what shape or form the cookies take, so long as they get to devour them, and stat.
Cookie bars also feed a crowd, which is perfect for SO many occasions. And because these sheet pan chocolate peanut butter oatmeal cookie bars in particular are one of those recipes that just turns out well every time – soft and chewy and rich and delicious – it’s a great standby dessert to make in a pinch any time you need to take a dessert to a gathering, serve up something sweet for a crowd, have a snack for a playdate, or add in a dessert at a party of your own. Also, I love gifting these bars since they stack up nicely.

And, in case I haven’t said it enough lately, chocolate and peanut butter were just meant to be. They’re two total all-stars when paired together, and I’m not sure I’ve ever encountered a chocolate peanut butter dessert I didn’t like. Also, the oatmeal gives them that perfect chewy texture and the chocolate coating is pretty epic.
Basically, your friends and family are going to adore these rich and delicious chocolate peanut butter oatmeal cookie bars, so get to baking!

Notes
By the way, you may have noticed that we often adapt our recipes or offer solutions to recipes to bake up vegan and dairy-free treats. That’s because our oldest daughter, Scarlett has MPIES (Milk Protein Induced Enterocolitis Syndrome). Over the years, we’ve changed a lot of our eating habits and I’ve made tweaks here and there in my baking to accommodate a dairy-free diet. We’re always experimenting with vegan and dairy-free recipes, in case you’re interested. Also, these chocolate peanut butter oatmeal cookies are incredibly moist, delicious, and can easily be made dairy-free; so basically, they’re perfect.
One of my secrets for yummy chocolate dairy-free desserts are these amazing chocolate chips. I use Dairy-Free Chocolate Chips (by Enjoy Life). The Enjoy Life Chocolate Chips are easily our favorite; they’re gluten-free, dairy-free, nut-free, and soy-free, and totally delicious. Also, they bake and melt incredibly well. Even Target carries them!
And speaking of chocolate, these chocolate peanut butter oatmeal cookie bars work great with milk chocolate, dark chocolate, semi-sweet, etc.; i.e., choose your favorite chocolate and roll with it. No matter what chocolate topping you go with, they’re going to taste AMAZING.

This feels like a dumb question but these are gluten free right? Have a potluck coming up with a gluten-free friend and this looks perfect!
It can be made gluten-free if you use oat flour (or gluten-free baking flour) instead of all-purpose flour. 🙂
