Preheat oven to 450 degrees and spray a ramekin (or small baking dish) with non-stick spray. Place ramekin on a baking sheet and set aside.
Heat olive oil in a pan over medium heat. Add garlic and jalapeños to the pan and saute until jalapeños are softened (approx. 7 minutes).
Add cream cheese, mayo and onion dip mix to the pan. Saute until cream cheese is softened and everything is combined.
Spoon dip into the ramekin and place in the oven (on the baking sheet). Bake for 5 minutes. Turn oven up to broil and cook for an additional 5 minutes - or until top begins to brown.
Remove from the oven. Allow to cool for 5 minutes.
