Ingredients

  • Cereal: any favorite variety adds crunch and is the backbone of the bars I like a mix of whole grain flakes and crispy rice cereal for best texture
  • Peanut butter or any nut or seed butter of choice: provides binding and rich flavor opt for pure nut butters with simple ingredients for best results
  • Agave honey or brown rice syrup: these act as natural sweeteners and help hold everything together always check for freshness and quality in your syrups
  • Salt (optional): just a pinch can brighten the flavors especially if using unsweetened ingredients
  • Protein powder (optional): a scoop adds staying power choose a clean brand with flavor you enjoy

Instructions

Peanut butter is my forever favorite here its creamy saltiness brings all the ingredients together and my son once licked the mixing spoon clean before the bars were set That was my first clue this was a keeper in our house

Storing Your Bars

Tuck bars into an airtight container and they will keep for over a week in the fridge For longer storage pop them in the freezer and take out portions as needed These bars do best in a cool spot so they hold their shape

Swap What You Want

Feel free to mix in chia seeds dried fruit or chocolate chips for extra variety If you do not have agave honey or rice syrup try maple syrup though you will want extra chilling time so the bars set up well

Ways to Serve

Serve as a grab and go breakfast a lunchbox treat or even a light dessert after dinner Crumble one over yogurt or frozen banana slices for a little twist

Preparation Steps

Step 01

Line an 8-inch square pan with wax paper or parchment paper. For larger batches, double the quantities and use a 9×13-inch pan.
