smoothies without bananas, peanut butter and milk

I’ve been looking into weight gain smoothies and almost all of them contain bananas, milk, and peanut butter. is there a way that I can make a high calorie shake/smoothie without using them? i wanted to do a fruit smoothie using protein powder, oats, olive oil, honey, literally anything else (except nuts, hate those too) but those three ingredients. this also includes ice cream, I don’t like milkshakes or ice cream in general so I don’t want mine to taste like it at all. is yogurt a good substitute? not a fan of that either but i’m more willing to try that

is it possible or am I just going to have to suck it up and use them anyway 😭
