    1. Preheat oven to 180 C / Gas 4. Lightly grease one 20x30cm baking tin.
    2. Mix together the flour and the caster sugar.
    3. In a saucepan, combine the Dr Pepper, cocoa and 225g butter; bring to the boil. Pour melted butter mixture over the flour and mix well. Stir in the beaten eggs, bicarbonate of soda, vanilla, buttermilk and mini marshmallows; mix well. Pour batter into the prepared tin.

    6. Remove cake from oven and spread peanut butter topping over warm cake. Place cake under the grill, about 10cm from the heat source. Grill for just a few seconds or until topping starts to bubble. Do not scorch. Let cake cool at least 30 minutes before serving.

    Tip

    If you can't find Dr Pepper, Coca Cola works a treat, too.

    I made this as a Valentine treat for the husband. Yikes is it SWEET! I left out about 1/4 cup of the sugar and it is still super sweet. If I make it again I might leave out a little more, maybe make it with 1.5 cups instead of the 2 called for...I mean you have DP, marshmallows, and that gooey sugary coating...I doubt the 1/2 cup of sugar will be missed!  -  14 Feb 2007  (Review from Allrecipes US | Canada)

    I got a request for Dr. Pepper cake. This recipe sounded pretty good so I gave it a try. The cake was sweet and moist. Everyone liked it and there were no leftovers.  -  08 Aug 2007  (Review from Allrecipes US | Canada)

    I added 1 1/2 tsp. cinnamon to the cake batter as per a similar recipe. Tasted like a moist chocolate cake - could not taste the Dr. Pepper in it. I used a chocolate glaze since I cannot eat peanut butter. Good cake, but don't expect any Dr. Pepper flavor.  -  03 Nov 2009  (Review from Allrecipes US | Canada)
