Make sure all ingredients are at room temperature. Preheat the oven to 175°C (convection oven 160°C). Mix the mix with 200 ml of water, 100 ml of vegetable oil and 3 eggs (150 g) and beat for 6 to 8 minutes until light and airy. Pour into a greased baking tin, filling it halfway to two thirds full. Bake for approx. 40 to 45 minutes until done. For cupcakes: divide the batter over approx. 20 paper baking cups and bake for 18 to 20 minutes at the same temperature. Perfect for filling or finishing with cream cheese frosting or buttercream.
