How to make a good weight gain shake at home?

[eyeothetiger]

Hi guys, yeah just looking to see how I'd make an alright tasting weight gain shake at home. I have strawberry cream whey protein and can obviously buy whatever else I need. I know a blender is a must but just interested in feedback from those that have done this

 

[mispronounced]

2 cups whole milk
1 scoop whey
2 chopped up bananas
4 tbs peanut butter

did that with chocolate whey, worked well. it would probably be fine with strawberry as well too
