Is there a sweet emulsion to put on oatmeal?

I’ve made a ton of mayo now with egg + lemon juice or vinegar + spices + oil and it got me thinking about sweet emulsions

I’ve been putting my savory mayo with various spices on rice and its quite nice so I’m thinking about trying to make a sweet emulsion of egg and butter with a sweet juice and maybe some sugar or other sweetener and trying it out on oatmeal!

Butter which is commonly used when you need something oily to go with sweet + eggs + a sweet fruit juice or something else sugary and sweet, maple syrup, agave, whatever you can think of, I can’t find anything about this while googling. I tried "sweet mayo" and it comes up with sweeter types of mayo but not stuff I’d want to put on oatmeal.

The closest thing I can find is hollandaise sauce but that is traditionally savory as far as I can tell?

I found a newspaper from 1964 with "grape hollandaise" during my research, it’s intended to be more savory though, still neat.

Are there any established sweet emulsions to put on foods that like sweet sauces? If not then what emulsions I can make to put on oatmeal or other foods that enjoy sweet sauces, pancakes, waffles, etc?
