In one bowl beat the egg and heavy whipping cream together.
In another bowl mix all the dry ingredients together. I like using a whisk, to give a similar affect a sifter would.
In your cooking bowl (Yes a bowl.), melt the 1/2 T of butter in a microwave. Once melted, move the butter around in the bowl (this will help it from sticking).
Pour the extra butter into the beaten egg and heavy whipping cream and mix.
Pour a third of the dry ingredients into the egg mixture. Once it's somewhat mixed, pour another third, and repeat.
Mix pretty well but some lumps are okay.
If you choose to use a flavor extract, go ahead and add it here. For the photos of this recipe, I used 1/2 t almond extract. Amounts of the extract you use, may be different. Start small and keep adding to your liking.
Lastly, pour your chocolate egg mixture into the buttered bowl.
Cook for 1:06 minutes. If you like a gooier cake, cook for less time.
