Chocolate Chip Peanut Butter Oatmeal Bites

Chocolate Chip Peanut Butter Oatmeal Bites ~ once you start popping these little bite sized cookies it’s practically impossible to stop!


It was tough to decide which deserved top billing with these cookies. The chocolate, the peanut butter, or the oatmeal? The chocolate won out, but only by a nose. They’re all equally responsible for the yumminess here. I had the same problem when it came to categorizing them…are they cookies? muffins? cups? I went with the noncommittal bites. They’re just a fun way to mix up the whole same old same old. They’re sturdy little things, so they make great lunchbox treats,  on the go snacks, or shippable care package stuffers.


These bites are baked in mini muffin pans. I used my 1 1/2 inch scoop to portion out the dough. The result is a cookie that looks like a tiny muffin. Be sure to grease the pan well so you can remove them easily, and it  helps to let them cool a good while in the pan before you attempt removal. You could also bake them in mini muffin paper liners to sidestep the whole issue.


The peanut butter and the oatmeal make them extra moist and chewy. My first batch was very moist so I added a bit more flour to the batter for the second batch. The second batch looked  more like a muffin with a rounded top. It’s a matter of personal preference, and the recipe below represents a compromise. You could experiment with all kinds of cookie dough, the benefit being that you’ll get a moister, chewier cookie because it’s not spreading out in the oven.

Chocolate Chip Peanut Butter Oatmeal Bites

Yield 2 dozen +
Author Sue Moran


  • 1/2 cup 1 stick unsalted butter, at room temperature
  • 3/4 cup brown sugar packed
  • 1/2 cup peanut butter
  • 1 Tbsp vanilla bean paste or vanilla extract
  • 1 large egg
  • 1 1/3 cup flour
  • 1/2 cup old fashioned oats
  • 1 tsp baking soda
  • 1 cup chocolate chips


  • Set oven to 375F
  • Grease and flour 2 mini muffin pans (or use paper liners)
  • Cream the butter, sugar, and peanut butter together until smooth. Beat in the egg and vanilla.
  • Mix in the flour, baking soda and oats.
  • Fold in the chocolate chips.
  • Fill the muffin cups almost full with a scoop of dough. I use my 1 1/2 inch scoop to make it easy.
  • Bake for about 12-15 minutes until risen and lightly browned.
  • Cool completely in the pan, on a rack before attempting to remove the cookies from the pan. Run a small blunt knife around the edge of the cookies to loosen them if necessary.

Cook's notes

You can use chunky peanut butter, or almond butter if you like.
The nutritional information for recipes on this site is provided as a courtesy and although tries to provide accurate nutritional information, these figures are only estimates.

When You scoop out the dough, press a few extra chocolate chips right into the top of the batter to get that nice ‘chock full of chips’ effect.

    Hi Sue!
    I have been enjoying your recipes for a while now.
    I tried making the oatmeal, PB and chocolate bites and they turned out rock hard tho tasty. What could have gone wrong? Thanks!

      They’re very small, so I would guess any over baking would make a big difference…maybe lower your oven temp or bake for a shorter time?

      These are quite small, so my guess is an oven that is too hot or slightly too long a baking time.

    I made these with my toddler last week and they were great! He wanted to add sprinkles (ha!) so we added them to the top of a few of them. Great, mini recipe 🙂

    I made these little morsels today. Crispy-ish on outside and moist on the inside. I used crunchy & smooth peanut butters. Very good. I’m sure my little ones will love them. Thanks for the recipe! 🙂

    the goodies that come out of a mini muffin tin are dangerous for me because i can never seem to say ‘whoa’!

    A little glass of milk and a few of your “beautiful bites” and I would be a happy camper! Bet they were good warm with gooey chocolate – hmmmmm.

    yum! and so pretty too…love the chocolate chips sticking out of the top. I really enjoy oatmeal/chocolate chip cookie mashups; there’s something lighter about them somehow, and i like to pretend they’re better for me. Are they? maybe, but i’d eat them anyway.

    These look so good that I’ll have to break my rule against buying single-use equipment. Mini cupcake pans, here I come.

    Great foodie pics, Sue! These gems look perfect. Clever idea to put some chips on top before baking. Makes them even more enticing.

    Oh YUM! These look dangerously pop-able — as in, I could probably eat a whole batch of them without thinking twice. Peanut butter, chocolate, and oats were just made for each other, weren’t they?

    Bites – the perfect name. These look so convenient to transport in a tin for sharing at morning tea.
