My wife was messing around with my Rubik's cube and made two-toned donuts. How did she do this? I can't find anything online and I think it looks really cool.

You obtain patterns like this one quickly by chance if you just twist random pairs of opposite sides in opposite directions repeatedly, so UD, LR or FB in cube notation.

With only those three sides showing, I came up with two possible cases you could have there. There could be more, but from the logical progression I followed, it looked like only two. As the other answer says, there's probably a solution with only UD LR and FB moves, but the solution I found to create this specific pattern from a solved state is:

U2 R2 D U B2 L2 F2 R2 F2 U2 B F L R D U

The other state I found can be created with:

F2 L2 B2 R2 D U R2 B2 R2 B' F L R D U
