How to Make St. Patrick's Day Shamrock Whoopie Pies
Here is a visual guide to making the green shamrock whoopie pies. A full printable recipe card can be found below.
Start by preheating the oven, lining a large baking sheet with parchment paper or a silicone baking liner and putting out your shamrock cookie cutter.
Gather your ingredients. If your butter isn't already soft, make sure to leave it in a warm spot so it will reach room temperature by the time the cake cut outs are ready to be filled.
Combine the cake mix, along with ingredients required on packaging PLUS cocoa powder and green gel food coloring. Mix well.
Spread the batter out on the parchment lined baking pan. Bake until edges are starting to brown and pick in center pulls clean. Start watching closely and checking after 10 minutes.
Once cake is out of oven and cool, cut out your green shamrocks.
Flip each over carefully so not to break them and save the scraps for a trifle, cake pops, or snacks!
Beat the frosting filling until fluffy then put in piping bag and pipe onto half of the shamrock cut outs.
Pop the other half of the shamrocks on top and gently press to adhere.

- Using a spatula, spread your cake batter onto your lined baking sheet. Baking time will vary, but it will be about 12-16 minutes (considerably less than standard cake timing).
- To make the buttercream, beat together butter, sugar and milk on medium speed. Gradually increase the speed to high.
