Put the butter, Lyle's, brown sugar, Guiness, ginger, cinnamon, and clove in a saucepan, and melt over low heat.
Take the saucepan off of the heat, and whisk in the flour and baking soda. It will be lumpy, but it comes together.
In a small bowl, whisk together the sour cream and eggs. Pour the sour cream mixture into the batter and mix until smooth.
Pour into a greased 9x13 pan and bake in a preheated 325 oven for 45 minutes.
