In a skillet, melt the butter and brown sugar, stirring until the mixture is creamy and bubbling. Stir in the lemon juice, then remove the pan from the heat.
¼ cup unsalted butter, ⅔ cup packed dark brown sugar, 2 teaspoons lemon juice
Line an 8 inch round cake pan with parchment paper and arrange the pineapple slices. Top with the brown sugar syrup.
5-6 slices tinned pineapple rings
In a large bowl, whisk together the buttermilk, oil, eggs, and vanilla. In a separate bowl, sift the flour, sugar, baking powder, salt, baking soda, and nutmeg.
⅓ cup vegetable oil, 3 large eggs, 1 teaspoon vanilla extract, 1 ½ cups all-purpose flour, ¾ cup sugar, 1 teaspoon baking powder, ½ teaspoon salt, ¼ teaspoon baking soda, ¾ cup buttermilk, ¼ teaspoon ground nutmeg
Add the dry ingredients to the buttermilk mixture and whisk until just combined. Gently fold in the coconut.
½ cup sweetened shredded coconut
Pour the batter slowly over the pineapple to avoid shifting the fruit. Bake the cake in the air fryer at 160ºC (320°F) for 15 to 20 minutes, or until a tester inserted into the center comes out clean.
Allow the cake to cool in the pan for 30 minutes. Then, place a serving plate over the cake and carefully invert the pan to reveal the pineapple on top. Decorate with raspberries.
Raspberries
Serve warm or at room temperature.
