Pineapple-Blueberry Crumble Cake
Note: The measurements were converted from US products. This recipe is so easy and flexible that a few grams here or there won't make that big a difference.
3/4 cup (170 gr) butter, plus more to coat the baking dish
1 20-ounce (566 gr) can crushed pineapple, in juice
1 20-ounce (566 gr) can blueberry pie filling
1 18.25-ounce (517 gr) box yellow cake mix
1 cup (225 gr) chopped pecans
Preheat oven to 350-F (180-C)
Butter the sides of 9x13 inch (23x33 cm more or less) baking dish with a bit of the butter.
Melt remaining butter in a small sauce pan over low heat
Pour entire can of pineapple, juice and all, and spread in the bottom of the baking dish
Layer blueberry pie filling over the pineapples. Try not to mix it in but make a layer.
In a mixing bowl, put in the cake mix and pecans.
Pour melted butter over the cake mix.
With fork, pair of knives, or pastry cutter, blend butter with pecans and cake mix. Mix will still be fairly dry. If the pecan pieces are too large for a pastry cutter, blend the cake mix and butter and then stir in the pecans.
Sprinkle cake and pecan mixture evenly over the blueberries.
Bake 30-45 minutes until top is golden
Can serve warm or cold
