Preparing Your Ingredients (quick pantry check)
Start by opening your cans and measuring. For a classic pineapple dump cake you'll need:
- 2 (20 oz) cans crushed pineapple, drained slightly
- 1 box (15.25 oz) yellow cake mix
- 1 cup sweetened shredded coconut (optional)
- 1/2 cup brown sugar (optional for extra caramel notes)
- 1 cup (2 sticks) butter, sliced thin
Tips:
- Drain canned pineapple but leave some juice — it keeps the cake moist.
- Use a handy can opener if you want a clean edge and safety.
- Measure faster with a set of stainless measuring cups and spoons.
The Mixing and "Dump" Technique (one-pan, no mixer)
This is literally a dump cake—no bowl mixing needed.
- Preheat oven to 350°F (175°C).
- Spread drained pineapple evenly in the bottom of your 9×13 glass baking dish.
- Sprinkle box of dry yellow cake mix evenly over the pineapple.
- Scatter 1 cup shredded coconut and 1/2 cup brown sugar over the mix if using.
- Place thin slices of cold butter across the top so they overlap slightly.
Pro tips:
- Use an offset spatula to nudge thin butter slices into gaps for even browning.
- Lining the pan with a strip of parchment paper helps if you plan to remove the whole cake later.
Baking, Timing, and Getting the Perfect Texture
Bake at 350°F for 35–40 minutes, until the top is golden and you see bubbling fruit at the edges.
- Watch for golden-brown top and active bubbling—these are your doneness cues.
- If the top browns too fast, tent loosely with foil for the last 10 minutes.
- For cleaner slicing, let it rest 10–15 minutes before serving.
Tools that help:
- Check doneness quickly with an instant-read thermometer (internal cake temp isn't exact here, but you'll catch hot spots).
- Protect hands with heat-resistant oven mitts when sliding the pan out.
Finishing Touches, Serving, and Storage (make-ahead friendly)
Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream. For neat slices, use a warmed and wiped knife or an offset spatula to lift portions.
Storage guidelines:
- Cool completely, then refrigerate covered for 3–4 days in airtight glass containers.
- Freeze portions up to 2 months in labeled freezer bags; thaw overnight in the fridge.
- Reheat individual portions in the microwave for 30–60 seconds or in a 325°F oven until warm.
Quick time-savers:
- Prep butter slices and measure cake mix into a freezer bag for true last-minute baking.
- Use nested mixing bowls to keep your station tidy while prepping toppings.
