There are a few ways to make the hummus more creamy. Although its time intensive, you can remove the chickpea skins from a can of chickpeas or home cooked chickpeas. You could also let the chickpeas simmer in 1/2 teaspoon of baking soda and water for 30 minutes which will soften them. Or if you are cooking your own chickpeas overcook them so they are softer which will result in a creamier hummus!
