Star's Favorite Fresh Bueberry Dump Cake

• butter flavored Pam cooking spray
• 1 (20 ounce) can crushed pineapple in juice
• 3 cups blueberries, washed and patted dry
• 12 cup sugar (white or brown)
• 2 teaspoons vanilla flavoring
• 1 (18 ounce) box yellow cake mix
• 1 cup pecans, chopped
• 1 cup butter, cut into tiny squares to cover the top of the dump cake

1. Preheat oven to 350 degrees F. Spray a glass 9" x 13" baking dish with Pam.
2. Pour pineapple in the bottom of baking dish and spread around.
3. Pour in the blueberries trying to cover the bottom evenly.
4. Mix together and sprinkle over the fruits: the sugar, vanilla, cake mix and pecans.
5. Cut the butter into little squares.
6. I cut each stick of butter into quarters lengthwise and then sliced.
7. Place the squares of butter all over the top to completely cover it so that it'll melt into the dry cake mix as it cooks.
8. You can peek at it a couple of times during baking and if there are floury areas that aren't getting moistened, just stir a spoon in it to let the juices bubble up around that area.
9. Bake in preheated oven for 45 minutes.
