Take a few pantry basics and turn them into crazy-good gluten-free cookie bars packed with three kinds of peanut butter goodness. These monster bars are stuffed with creamy peanut butter, peanut butter chips, and mini Reese's pieces. Thanks to the oats, they're extra chewy. Super for passing around or stashing in the freezer so you always have a sweet treat ready.
I love peanut butter combos, which is how these bars came to life. The first batch, my family took one bite and their faces lit up. That's when I knew this one would be a total hit.
Legendary Elements
- Mini Reese's pieces: Gives a pop of crunch and color
- Pure vanilla: Makes the peanut butter flavor pop
- Brown sugar: Helps get that chewy bite
- Fresh oats: Use both quick and whole style for fun texture
- Quality butter: Brings a buttery base
- Regular peanut butter: Go for classic creamy versions
Making Bar Bliss
- Final Step:
- Gently stir in Reese's pieces and peanut butter chips. Spread everything in your pan nice and even so it all bakes up the same.
- Oat Mix Time:
- Add both oats plus baking soda. Make sure it's all spread through the dough evenly.
- Add the Binders:
- Drop in the eggs and vanilla. Mix until it's nice and smooth and all together.
- Start with the Base:
- Beat together butter, peanut butter, and both sugars until the mix is light and airy. Don't rush—fluffy is the goal.
