Set your oven to 350°F (175°C) and let it heat up while you prep.
02 -
Lightly grease a 9×9-inch pan so the bake doesn't stick and is simple to scoop out.
03 -
Combine the canned crushed pineapple (with juice), sugar, vanilla extract, eggs, and cornstarch in a big bowl. Stir it all together well until you see a smooth, even mix without any lumps.
04 -
Spoon your pineapple mixture into the greased pan. Spread it out so it's nice and level.
05 -
Scatter the butter chunks evenly over the top. Then sprinkle the cinnamon across the surface.
06 -
Pop the pan into the oven and bake for roughly 45 minutes. Once the edges are golden and the middle is solid, it's ready. Check by inserting a toothpick—if it comes out clean, you're good.

Take it out of the oven and let it cool for a bit. It's great warm or cooled down. Add a scoop of ice cream or some whipped cream if you like.
