Quick 1 Egg Chocolate Guinness Cake

This is a 1 bowl quick to beat together, moist, crumbly chocolate cake.  Just what you need when you open the fridge and are greeted with 1 egg and need a cake! It is not too sweet and topped with a light, cream cheese icing that compliments the cake well and equally served plain is as delicious.

You can’t taste the Guinness, but it gives a delicious moistness and as my Irish friend says Guinness contains a lot of iron so is ‘healthy’ for you too. The cake makes for a great talking point and an unusual take on a chocolate cake and the children at the table ate the cake without detecting the bitterness sometimes that comes through when you cook with Guinness. This differs from other chocolate Guinness cakes in that they are quite dense, rich and delicious. Mine is lighter with the yogurt and is more of a crumbly traybake than dense rich cake and still delicious.

Ideas for when to bake the cake:

Watching the Ireland rugby match.

St Patricks Day celebrations.

This can be a great bake for Easter, after you may have abstained from alcohol and chocolate, you can sink mini eggs or Lindt eggs onto each slice.

Father’s day or for a Guinness lover’s birthday, you could cut the cake into the shape of pint glass and frost the top.

A coffee morning bake.

A little square for an afternoon tea selection.

The photo I took on the day that I made this cake was not picture perfect. I should have used a sharp knife to cut the cake not a butter knife but the taste was delicious.
