Step 1

Unpeel the bananas.

Step 2

Slice each banana into 1/2-inch thick slices.

Step 3

Line a large baking sheet with parchment paper. Arrange the banana slices in a single layer, leaving space between each one. This will ensure the bananas freeze separately and prevent them from sticking together.

Step 4

Flash freeze the bananas for 1 to 2 hours, or until solid. Flash freezing also keeps the banana chunks from sticking.

Step 5

Using a spatula, remove the frozen banana slices from the baking sheet and place them in a freezer-safe bag or airtight container.

Step 6

Return to the freezer until completely firm, about 6 hours.

Step 7

Unpeel the bananas.

Step 8

Line a large baking sheet with parchment paper. Place the unpeeled bananas on the sheet, leaving space between each one. Again, this will prevent the bananas from sticking.

Step 9

Flash freeze the bananas for 2 hours, or until solid.

Step 10

Remove the bananas from the baking sheet and place them in a freezer-safe bag or airtight container.

Step 11

Return to the freezer until completely firm, about 6 hours.

Step 12

Place whole unpeeled bananas in the freezer until firm, about 8 hours.
