Grandma always said, ‘A ready oven is a happy oven.’ Preheat yours to 325°F and prepare two 8-inch pans by lining them with parchment paper and greasing the sides.
n a large bowl, whisk together the cake flour, half the sugar, baking powder, and salt. Grandma used to hum while whisking—it somehow made the batter fluffier, or so she claimed.
In a second bowl, mix the egg yolks, oil, milk, and vanilla. It should look creamy and pale, like a golden sunrise, just how Grandma liked her mornings.
In a clean bowl, beat the egg whites with cream of tartar until foamy. Slowly add the remaining sugar and beat until stiff peaks form. Grandma always said, ‘If you can turn the bowl upside down and it doesn’t move, you’ve done it right
Gently fold the fluffy whites into the yolk batter in thirds. Add the drained pineapple at the end. ‘Like dancing with clouds,’ Grandma used to whisper while folding.
Pour the batter evenly into your pans and smooth the tops. Bake for 25–30 minutes, or until a toothpick comes out clean. Cool in the pans for 10 minutes, then transfer to racks.
Beat the cream cheese until smooth, then mix in powdered sugar. Separately, whip the cream and cornstarch until stiff. Fold whipped cream into the cheese mixture and stir in pineapple concentrate. Grandma said to always taste at this point—‘Frosting should make your toes curl in happiness.
Place one cake layer on your stand. Spread frosting and a spoonful of pineapple. Top with second layer and frost the whole thing. Chill for at least 2 hours to let everything settle—just like Grandma used to do before guests came over.
