Line a baking sheet with a silicone mat or parchment paper and set aside. Cut each banana in half crosswise, then peel. Insert a craft stick into the center of the cut end of each banana and place on the lined baking sheet, making sure to leave a little space around each banana. Transfer to the freezer until firm, at least 30 minutes.

Coarsely chop cooked bacon and pile it up on your cutting board or a plate.

Place peanut butter in a microwave safe bowl or measuring cup. Microwave on high for 15 seconds, stir, then microwave for another 15 seconds and stir again.

Remove tray of bananas from the freezer. One at a time, dip each frozen banana into the peanut butter, using a spoon to coat the whole thing and smooth it out if necessary. Immediately roll the peanut butter-covered banana in the chopped bacon to coat all sides, then place back onto the baking sheet. Repeat with remaining bananas.

Transfer baking sheet back into the freezer and let set until completely frozen, about 3 hours. Once frozen, bananas can be stored in a freezer bag or other airtight container.
