St. Patty’s Surprise Inside Cookie

Come March, I find that St. Patty’s Day can’t arrive soon enough. Immediately my mind jumps to shades of green everywhere, shamrocks, and those silly little pinches you’ll get for not wearing green. This rolled cake-cookie – officially dubbed the St. Patty’s Surprise Inside Cookie – is festive, green, and a yummy treat. With only 7 ingredients, including the sprinkles, you’ll be pleased to find how easy this recipe is! This year St. Patty’s Day falls on a Saturday, so the plan is to invite a few of the boys’ friends over, and pair this green drink with fruit shamrocks with the cookies to complete the party. I’m fairly certain St. Patrick himself would approve of such a dessert table.

The perfect shamrock cookie - surprise!


  1. Make the dough
  2. Cut out the shamrocks
  3. Shape and roll
  4. Bake

This recipe was adapted from Eugenie Kitchen’s darling Rainbow Heart Cookies.

Stack the shamrocks up and use egg wash to make them stick together


One of the biggest take-aways from this recipe is that the dough needs to be slightly chilled to assemble. Each chilling period should really take a full hour, so give yourself time to come back to this recipe in steps. Patience, folks! I promise the time and effort will be worth it.

With that being said, mix up the dough and roll it out, splitting it into thirds. Apply green food color to one third. Give it a good knead so that the color is distributed evenly. Chill in the fridge for one hour.

Stack the shamrock shaped dough and place on another rolled out piece of sugar cookie dough


Roll out the green dough and cut using a shamrock cookie cutter. Pile up the shamrocks but make sure to brush an egg wash in-between the shamrocks. Put back in the fridge for an hour.

Wrap the dough around the stack of shamrock cookie cut outs


Take the vanilla dough and wrap the shamrock stack like a cylinder. Put back in the fridge for one hour.

Roll the cylinder of shamrock cookies in rainbow sprinkles

Brush the wrapped-and-stacked cookies with egg wash, and roll in sprinkles. You’ve nearly reached the end of the rainbow, folks!

Carefully slice each shamrock cookie onto parchment for baking

Slice the cookies where it feels like there’s some give. Stick back in the fridge for a final 30 minutes (last time, I promise!).

Bake for 10-12 minutes at 350 degrees. There you have it! There’s a slice of luck with each St. Patty’s Surprise Inside Cookie for ya lasses and laddies.

      Super festive. I love St. Patty’s Day – it makes March a little more manageable. 😉

  • This is so very clever! I would never have thought of piling up the shamrocks like that! And those sprinkles make these cookies so much fun!

      In my opinion, the sprinkles really make these cookies. I love the rainbow rims with the green dough.

    I have always wanted to make these instead of buy them. They’re so cute and not as hard as I thought!

      Great point – kids would love to make them. This recipe translates to any shapes you want, for any holiday.

    I love these! Plus they’re so much healthier (maybe?) and fresher than the store-bought cut and slice dough. Super cute!

    • Cindy "TheSweetNerd" Rodriguez

      They are healthier because you know every single ingredient that is going into the dough. Not so with the store bought!

    I never knew how to get the shapes inside the cookie – thanks for enlightening me!
