Chocolate cake recipe + buttercream = the most beautiful St. Patrick’s Day Cake! Inspired by the beauty of shamrocks and all things green, this 2-layer naked Shamrock Cake is sure to be a crowd pleaser!
This cake comes together quite easily once you have prepared. I start by making the chocolate cake recipe listed below in a 15×10 sheet pan. (Be sure to see my notes for baking times!) Allow cake to cool completely.
Create a template for your shamrock. You can freehand draw a shamrock on a piece of paper or print one off of the internet. Be sure that the size is correct! You will need to cut out 2 shamrocks from your sheet cake.
Next, I prepared the buttercream. Separate it into 4 bowls and then tint various shades of green. Start by adding a little McCormick green food coloring to one, then a little more to the next and so on. Place the buttercream in pastry bags fitted with decorating tips. I used an #2D, #9FT, #32, and the final tip didn’t have a number (the tip with the lightest green frosting in it) but is very similar to a #32. Feel free to use whatever tips you have on hand! This St. Patrick’s Day cake design is open to all interpretation.
Because it’s a 2-layer naked cake the bottom layer of frosting can be a fun “practice” layer. You can experiment with your piping and find out which techniques you like the best. Then the top layer can be covered with your favorite swirls and dollops!
I know that cake decorating can be intimidating but this is one of those cakes that you can’t screw up. No matter how you choose to do your dollops and swirls it will be beautiful! Want proof? Let your child or friend who has never decorated cakes try it. They are so pleasantly shocked and encouraged by the ease of this design and then the stunning final product.
If you have never decorated a cake this is the cake for you. If you have decorated a 1,000 this is the cake for you. Simple design paired with amazing taste is always a winning combination!

Now, you may be thinking “that’s a lot of frosting!” But it’s not! Truly. This is a naked cake so those fun frosting dollops are the perfect amount of frosting on each individual slice. You can always use more or less depending on your tastes!
For this St. Patrick’s Day cake I prepared the above chocolate cake recipe in a 15×10 baking sheet.
Bake at 350°F for 20-26 minutes. The center should no longer appear wet and if you press your finger into the cake it should spring back.
I used this buttercream recipe.
For a fun variation try making your chocolate with Stout beer instead of coffee! You can also use hot water in place of the coffee.
