Add in the flour and cornstarch. Mix with a fork until the ingredients come together to form a ball.
Knead the ball, in the bowl or on the counter until it comes together to create a playdough-like consistency. This takes roughly 5 minutes but could be faster if you're quick.
The texture when you're done should be soft, fluffy, almost dough-like and a little oily. This is fine, and the kids love it!
Notes
When kneading the playdough, aim for a similar technique to kneading yeast bread. This helps break down the banana chunks and transforms the mixture from a thick banana bread batter to a playdough consistency.Choice of Oil: You can use any type of cooking oil, such as canola, coconut, or vegetable oil.Shelf Life: Due to the use of a ripe banana, it's recommended to use the playdough within two days. It's best enjoyed as a "make it and play with it right away" type of activity.Gluten-Free Option: Yes, you can use gluten-free flour to accommodate those with wheat allergies.How to Store Banana Playdough:
Store the playdough in an airtight container or a resealable plastic bag in the refrigerator when not in use. Although it may require a few minutes to warm up and become pliable again after refrigeration, this helps keep it fresh.
