These are the snack I make when I want something a little sweet that does not leave me hungry twenty minutes later. Peanut butter, oats, a spoon of honey, ground flax, and a scoop of protein powder, rolled into little balls and chilled. No baking, one bowl, about ten minutes of actual work.

I keep a container in the fridge and grab two when the afternoon dips. The kids like them too, which is the highest praise a snack gets around here.

“Peanut butter, oats, honey, a scoop of protein. Roll, chill, and the afternoon slump never stands a chance.”
Why this one earns a weeknight

What you'll love about it

  • 01No oven, one bowl, and about ten minutes of hands-on work for a week of snacks.
  • 02Real staying power. Peanut butter, oats, flax, and protein powder keep you full, not just briefly sweet.
  • 03They travel. Tuck a couple in a bag for the car, the gym, or a desk drawer.
  • 04Endlessly adjustable. Swap almond butter, add chia, use maple for vegan, dial the chocolate up or down.

Chill the dough first, then roll. Cold dough rolls cleanly instead of sticking to everything.
Ingredients

For the protein balls

  • 1 cupold-fashioned rolled oats
  • ½ cupnatural peanut butter
  • ⅓ cuphoney or maple syrup
  • ⅓ cupvanilla or plain protein powder
  • ¼ cupground flaxseed
  • 3 Tbspmini dark chocolate chips
  • 1 tspvanilla extract
  • pinch of salt
  • 1 to 2 Tbspmilk or water
Method

How I make it

  1. 01
    Mix the base.
    In a medium bowl, stir together the oats, peanut butter, honey, protein powder, ground flax, chocolate chips, vanilla, and a pinch of salt until it comes together into a thick, sticky dough. Different protein powders soak up different amounts of moisture, so if it feels too dry to hold together, add milk a tablespoon at a time until it does.
  2. 02
    Chill the dough.
    Pop the bowl in the fridge for 15 to 20 minutes. The dough firms up as it sits, which makes it far easier to roll without sticking to your hands.
  3. 03
    Roll and store.
    Roll the dough into balls about 1 inch across (a small cookie scoop makes this fast and even). You should get around 20. Store them in a sealed container in the fridge.

A note from Anna

The single most useful trick here is to chill the dough before you roll. Warm peanut butter dough sticks to everything and rolling it is a sticky, frustrating mess; twenty minutes in the fridge fixes that completely. The other thing is moisture: protein powders vary a lot, so add the mixture together first and only splash in milk if it will not hold a ball. You want a dough that just barely comes together, not a wet one.

What to serve with it

Round out the table.

  • ·01
    A cup of coffee or tea
    These are very much a 3pm-with-a-hot-drink kind of snack.
  • ·02
    An apple or a banana
    If you want to round it into something closer to a small meal.
  • ·03
    A glass of cold milk
    The kids' preferred pairing, and honestly not bad.
Storage & reheating

Keeping the leftovers good.

Fridge: Keep in a sealed container for up to 1 week. They firm up cold, which is how I like them.

Make ahead: This is the whole point. Roll a batch on Sunday and snacks are sorted all week.

Freezer: Freeze for up to 3 months in a sealed bag. Thaw a few in the fridge overnight, or eat them straight from frozen for a firmer bite.
