Mix basic ingredients to create mouthwatering gluten-free bars packed with triple peanut butter flavor. These crowd-pleasing treats blend smooth peanut butter, peanut butter chips, and mini Reese's pieces with wholesome oats, giving you a chewy, delightful dessert that's great for parties or stashing in your freezer for later.
I came up with these bars because I can't get enough peanut butter combos. When my family tried them the first time, their faces lit up with each bite, and I knew I'd stumbled onto something truly special.
Key Ingredients
- Standard peanut butter: Stick with smooth, regular type
- Good butter: Forms the tasty base
- Reliable oats: Combo of regular and quick for best bite
- Brown sugar: Gives that perfect chew
- Real vanilla: Boosts the peanut butter taste
- Tiny Reese's pieces: Add fun pops of color and bite
Baking Your Bars
- Mix Your Base:
- Beat together butter, peanut butter, and sugars until they're super fluffy. Don't rush this step – you want that airy texture.
- Add Wet Stuff:
- Mix in eggs and vanilla until everything's smooth and well-combined.
- Blend Dry Parts:
- Stir in both kinds of oats and baking soda, making sure everything's evenly mixed.
- Finish It Off:
- Carefully fold in your peanut butter chips and Reese's pieces. Press everything flat in your pan so it bakes evenly.

What makes these so good is how the different oat types work with all that peanut butter goodness. You'll get the perfect chewy bite loaded with rich nutty flavor.
Tasty Companions
Try them slightly warm with a glass of cold milk. They're also great on a dessert platter with other cookies. Kids love finding these in their lunch boxes or munching them after school.
Switch It Up
Throw in some chocolate chips if you want more sweetness. Switch out the candy pieces for something different. Make them festive with holiday-colored candies. Make a double batch when you've got lots of people coming over.
Keeping Them Fresh
They'll stay yummy in an airtight container for about four days on your counter. Pop them in the fridge and they'll last up to a week. Wrap pieces individually and freeze them for up to two months.

These triple peanut butter treats have become my go-to for parties and get-togethers. The mix of different peanut buttery elements makes them vanish fast, and people always ask for more. They're just right for any time you need to feed a bunch of folks or want to stock up on tasty snacks.
