Here are some simple variations you can use for a mug cake: (I love the peanut butter one and I also use nutella...yuuummm!)
-Chocolate Chip - Add chocolate chips of course. Simple but delicious
-Vanilla - Replace the cocoa powder with custard powder. Check the timing and don't cook too long.
-Fruit Sponge - Place fruit in the bottom of the mug and mix in another container. Pour half the mixture over the fruit before cooking as usual. One recipe will make two mugs this way. To make it a vanilla fruit pudding leave out the cocoa and add custard powder. When cooking half the mixture this way, half the timing too. e.g. 1.5 minutes in 100W microwave.
-Very Lemon - Add lemon juice and lemon zest. Leave out the cocoa and vanilla and add extra flour. Check timing for your oven.
-Poppy Seed and Almond - Add almond essence and a teaspoon of poppy seeds. Leave out the cocoa and add a little extra flour. Watch the timing as it might need a little less time than the chocolate.
-Ginger Pudding - Add ground ginger and crystalised ginger chopped finely. Leave out the cocoa and add a little extra flour.
-Chocolate Cherry - Simply add chopped glace cherries, or add cherries and coconut
-Chocolate Peanut Butter - Add some small blobs of peanut butter before cooking. Or put a larger lump in the middle. Chunky peanut butter works best for this
-Surprise Cake - Add a small lump of something interesting to the centre before cooking. Try cream cheese, marmalade or jam. (This will be hotter than the cake so take care)
