Chocolate Lava Mug Cake

 Chocolate Lava Mug Cake

This Chocolate Lava Mug Cake is perfect for those times you crave something sweet, but don’t want to whip up a whole cake or dessert.  Mug cakes have a bit of a reputation for being either too rubbery or eggy, but this mug cake is perfectly fluffy.  The secret is to not cook the cake too much; if anything it’s better slightly under done than over, which will give the cake a fudgy texture.

This is not another plain mug cake!  It has a delicious gooey chocolate centre that adds a great sauce to the cake.  To make the ‘lava’, you just top the cake batter with chocolate chips (which is what we have used), or broken up chunks of chocolate.  The chocolate doesn’t need to be pushed into the batter at all, just leave it sitting on top and the cake will rise around it as it cooks.  Finally, pour a tablespoon of water of the chocolate and pop in the microwave for a minute or so.

It might take a little practice to work out exactly how long your mug cakes will take to cook in your microwave, give that all microwaves are different.  Mine is a little older than the newer, higher powered microwaves so it took a little over a minute for me, but you might find a minute to be perfect in your microwave.

As tempting as it is to dive into your hot mug cake with a spoon,  it’s best to let it sit for a few minutes before eating.  To start with the lava centre will be very hot, and secondly it just gives the lava centre a few minutes to take on a saucy consistency.  If you want to take this dessert a step further, drizzle with a little cream or top with a scoop of ice cream.  This recipe will make a good size serving for one.
