How to make the font bolder than the maximum weight of the outline?

Question

Fonts

I liked the Comfortaa font, but its maximum weight is not suitable for me, I need it even thicker, maybe there are some options to solve this problem?
I tried to add a shadow and due to this the thickness increased, but this is a crutch.

This is of course a dumb decision, but if you really want ...

h1 {
  -webkit-text-stroke-width: 3px;
  -webkit-text-stroke-color: black;
}
