I would make a vanilla ice cream base and experiment with the lavender component.

Every lavender ice cream recipe I have also includes honey, so you might want to think about that.
If you're interested in getting a book, I recommend David Lebovitz's book, The Perfect Scoop. It includes a recipe for lavender-honey ice cream.
And here's an on-line recipe from Leite's Culinaria, http://leitesculinaria.com/4349/recipes-lavender-honey-ice-cream.html
Just be extremely cautious about the amount of lavender you use. Your ice cream can easily wind up tasting like soap or hand lotion.
Personally, I would steep the lavender in the cream and strain it. That, or pound it into (or grind it) a fine powder.
Walnuts would be good in there, too.
