I may not be known for my baking, but I am kind of famous for my chocolate mint cake.  Two layers of chocolate mint cake with mint cream cheese frosting, yes!  It’s easy peasy and I make it every year for St. Patrick’s Day.

I clipped this recipe out of a magazine almost 20 years ago, and I’m still making it.  Almost every year I put out a big spread for St. Pat’s Day and this is dessert.  My good friends and family have come to expect it.

The chocolate cake bakes in a jelly roll pan and then is cut in half crosswise, giving you the two layers.  The frosting is a traditional cream cheese frosting with added mint extract.  It’s just the right amount of mint, not at all overpowering.

If you like chocolate mint, you will love this cake.  Make it for St. Patrick’s Day next week, or make it any time you’re feeling a wee bit Irish.  Or what the heck, just make it anytime because it’s so good!  And just ignore the crumbs in my frosting, yours will be perfect. ? Kelly
