Heat the oven to 180C/160C fan/gas 4. First, make the topping. Beat the butter and sugar together with an electric whisk until creamy, then mix in the rum. Spread over the base and up the side of a 20cm cake tin (ensure it is not loose-bottomed). Arrange the pineapple rings on top.
Tip the flour, baking powder, butter, sugar, eggs, rum, black pepper and vanilla into a large bowl, and beat with an electric whisk until the mixture is completely combined, soft and fluffy.
Spoon the mixture over the pineapple rings and carefully smooth with a spatula, being careful not to disturb the pineapple. Bake for 35-40 mins, then leave to cool in the tin for 5 mins. Meanwhile, for the rum cream, whisk the cream, sugar and rum to soft peaks using an electric whisk. Invert the cake onto a plate and serve warm with the cream. Or, leave to cool completely. Will keep covered at room temperature for up to three days.
