Roast the pecans. (In the oven for about 12 minutes at 325°F.)
Brown the butter: Put the soften butter (3/4 cups) in a saucepan and melt at low-medium heat. Let the butter sizzle. When it stops crackling it means the water has evaporated and it should start frothing. At this point use a spatula to verify the color of the melted butter and when it looks like light caramel take of the heat and poor into a bowl.
Sizzling butter
In a mixing bowl, cream brown butter, vegetable oil and sugar.
Add 1 egg at a time in the mix.
In another mixing bowl, mix together all dry ingredients except the sugar since it was added at step 3.
Add white chocolate, pecans, grated carrots and pineapple, then whisk together until combined. Don't whisk to much.
Pour mixture in 3 greased molds
Bake for 45 minutes at 350°F.
Cream Cheese Frosting

Gradually add the icing sugar.
Decoration:
