Perfumed Pineapple Oat Crumble

This is a favorite from the French cookbook my friend Jessica brought me. The original attempt (with way too much butter after the conversion from metric and translation) is here:

I did some alterations today, trying to make it heartier/healthier.

Ingredients:
- 2 small pineapples
- real vanilla
- brown sugar
- butter
- flour
- oats

Cut the pineapple and 'perfume' with about 2 teaspoons vanilla.

Grease dish with butter. I used my Le Creuset skillet today.

Sprinkle with brown sugar. The original suggests 3 tablespoons. I didn't measure.

Arrange pineapple in the bottom of the dish.

Make sandy crumbs with remaining ingredients. The recipe suggests 2 more teaspoons vanilla, 2 cups flour and 2 cups brown sugar. And butter -- at room temperature.

I tried:
- vanilla
- one cup unbleached flour
- one cup oats
- one cup brown sugar
- 1/2 stick butter

Cover pineapple with crumbs and bake for 45 minutes at 350.
