Prepare a dish that can be stored in the freezer by lining it with parchment paper. Slice bananas into 1/2-inch disks layer them on the prepare dish until you have 25 disks.

Dollop 1/4 teaspoon of peanut butter on each banana disk. Then, dip your finger in water and smooth out the dollop so it's evenly spread over each banana disk. Freeze bananas for 30 minutes MAX to firm up the peanut butter. This will make it easier to dip in chocolate.

Melt chocolate in microwave in 30 minutes intervals until completely melted, stirring after each interval. Remove bananas from freezer and dip in melted chocolate. Shake off excess chocolate and place back on parchment paper to dry. Repeat with remaining bananas. Freeze for a couple week or enjoy immediately at room temperature.
