This pineapple poke cake skips the Jello in favor of a fresh pineapple syrup that soaks into every bite — topped with coconut whipped cream and toasted coconut for the ultimate tropical summer dessert. Serves 12 and tastes even better the next day.
Preheat oven to 350°F. Grease a 9x13-inch cake pan with non-stick spray or butter, then dust with flour.
In a large bowl, whisk together cake mix, flour, sugar, salt, eggs, crushed pineapple (undrained), melted butter, milk, and sour cream until just combined.
Pour batter into the prepared pan. Bake 43–48 minutes until a toothpick inserted in the center comes out clean.
While the cake bakes, make the pineapple syrup: bring pineapple juice and sugar to a boil over medium-high heat. Cook 5–7 minutes, stirring frequently, until thick and syrupy. Remove from heat and whisk in butter.
While the cake is still piping hot, poke holes 1 inch apart all over the surface with a skewer, chopstick, or wooden spoon handle.
Pour hot pineapple syrup evenly over the hot cake. Cool completely, then refrigerate at least 1 hour (overnight is best).
Make whipped cream: beat cold cream, confectioner's sugar, and vanilla until stiff peaks form. Fold in sweetened coconut.
Spread coconut whipped cream over cooled cake. Top with toasted coconut if desired. Serve cold.
Notes
Do NOT drain the crushed pineapple — the juice goes into the batter and the syrup.
Best made 1 day ahead — the flavor improves significantly overnight.
Cool Whip substitute: Fold ½ cup sweetened coconut into 2 cups Cool Whip.
Toasted coconut topping: Spread coconut on a baking sheet and toast at 350°F for 5–7 minutes until golden.
Gluten-free: Use a 1:1 GF cake mix and GF all-purpose flour.
Storage: Refrigerate covered 3–4 days. Freeze untopped cake up to 3 months.
