<human>:  How can I make a simple, delicious cake?
<bot>: To make a simple and delicious cake, you will need all-purpose flour, baking powder, sugar, butter, eggs, and vanilla extract. Preheat your oven to 350 degrees Fahrenheit. Mix together the flour, baking powder and sugar in a large bowl. In a separate bowl, mix together the melted butter, eggs and vanilla extract until evenly combined. Add the wet ingredients to the dry ingredients and mix until just combined. Grease a round cake tin and pour the cake batter into it. Bake in the preheated oven for 30-35 minutes, until the cake is golden and a toothpick inserted into the center comes out clean. Let the cake cool in the tin before serving. Enjoy!
