Instructions:
Preheat your oven to 350°F (160°C) and grease a 9×13" baking dish or two cake tins.
In a mixing bowl, sift together the all-purpose flour, sifted cake flour, cornstarch, baking powder, baking soda, and salt.
In another bowl, whisk together the canola oil, sour cream, granulated sugar, eggs, and vanilla extract until well combined.
Gradually stir the dry flour mixture into the wet ingredients until just incorporated. Be careful not to overmix.
Gently fold in the crushed pineapple, along with its juice, using a spatula until evenly distributed.
Lightly tap the cake tins on the counter to remove any air bubbles from the batter.
Pour the batter into the prepared baking dish or divide it evenly between the two cake tins.
Bake in the preheated oven for 20-25 minutes for a 9×13" dish, or 30-33 minutes for cake tins, covering with foil if the tops start to brown too quickly.
Once baked, allow the cake to cool in the tins until it reaches room temperature.
Then, carefully remove the cakes from the tins and transfer them to a wire rack to cool completely.
Meanwhile, prepare the pineapple filling by combining crushed pineapple, sugar, cornstarch, milk, and lemon juice in a saucepan.
Cook until thickened, then let cool.
For the frosting, whip the mascarpone cheese with icing sugar and vanilla until smooth, then whip the cream separately until stiff peaks form and fold into the mascarpone mixture.
Once the cakes are completely cooled, assemble by spreading the pineapple filling between layers and frosting the top and sides with the pineapple whipped cream frosting.
Garnish with toasted coconut if desired.
To guarantee your Moist Pineapple Cake turns out perfectly, remember to accurately measure your ingredients and avoid overmixing the batter, as this can lead to a denser cake. Additionally, using fresh ingredients will enhance the overall flavor.
Cooling the cake in the tins prevents it from drying out, and using fresh ingredients will enhance the overall flavor.
