What are other techniques to make garlic bread? I've usually made garlic bread by pouring over the bread with special garlic bread powder over spread butter. This works, but is there any way to make the garlic sauce/powder on your own?
I find garlic powder to be kind of meh when making garlic bread. I suggest using fresh garlic that is finely minced that has been mixed with softened butter. You simply spread it on, cook, and enjoy.

Here is a recipe demonstrating this technique (I have not used the recipe):
