  1. Popcorn: You can use air-popped, unflavored microwave popcorn, or stovetop popcorn (see here for how to make perfect stovetop popcorn).
  2. Marshmallows: I like to use mini jet-puffed marshmallows. Make sure they’re fresh and not stale, so they’ll melt into a soft and gooey texture.
  3. Butter: Unsalted is my favorite kind of butter and that’s all I have in my house, so that’s what I use. If you’re using salted butter, omit the salt from this recipe.
  4. Bailey’s Irish Cream: An alcoholic drink flavored with cream, cocoa and Irish whiskey.
  5. Salt: Salt, in small amounts, enhances the taste and flavor of sweetness.
  6. Add-ins – I used St. Patrick’s Day sprinkles, confetti, marshmallows.

Bailey’s Irish Cream gives this St. Patrick’s Day dessert an extra kick to it. It’s a quick and easy treat to make at home. You can add in whatever goodies you have on hand and get as creative as you want to.

Step 1: Make 10 cups of popcorn. I like to make stovetop popcorn (see my recipe for perfect stovetop popcorn here), but you can use air-popped or unseasoned microwave popcorn. Use 1/3 cup popcorn kernels to make 10 cups of popcorn.

Step 2: Make sure to remove all un-popped kernels.

Step 3: Place popcorn in a large bowl and set aside.

Step 4: Line a large, rimmed baking sheet with parchment paper or a Silpat baking mat.

Step 5: In a medium saucepan, melt 3 Tbsp butter over medium-low heat.

Step 6: Add in 5 cups of marshmallows and 1/3 cup of Bailey’s.

Step 7: Stir mixture until the marshmallows are about 75% melted. The residual heat will continue to melt the marshmallows.

Step 8: Remove the marshmallow mixture from the heat and stir in the salt.

(See my recipe for popcorn marshmallow treats here for more detailed instructions and tips)

Step 9: Slowly pour about a third of the marshmallow mixture over the popcorn and gently fold into the popcorn.

Step 10: Continue adding marshmallow mixture a little at a time and folding it into popcorn. Completely cover the popcorn with the marshmallow mixture.

Step 11: Pour popcorn onto prepared baking sheet.

Step 12: Use spatula to spread popcorn evenly on baking sheet. Press gently so you don’t smash the popcorn.

Step 13: Now for the fun part! Time to mix the add-ins into the marshmallow popcorn. While the popcorn is still a bit warm (if it’s too cool the sprinkles won’t stick to it), sprinkle the candy onto the popcorn.

Step 14: Let the St. Patrick’s Day popcorn cool. Pull apart and enjoy!

What Other Mix-Ins or Decorations Can I Use?

  • St. Patrick’s Day m&m’s
  • Different colored marshmallows
  • Drizzle on melted green chocolate 
  • Drizzle on white or green candy melts 
  • Lucky Charms cereal
  • Food coloring to make green popcorn

The possibilities are endless!

How Long Will the St. Patrick’s Day Popcorn Marshmallow with Bailey’s Last?

Any kind of marshmallow popcorn doesn’t generally last very long in my house! This St. Patrick’s Day popcorn recipe tastes best right after it’s made, but it’ll last about 3 days if stored in an airtight container (see here for storage tips and how to keep popcorn fresh). The popcorn does get a bit chewier over time as the popcorn absorbs some of the moisture from the marshmallows, but it still tastes good!

How Do I Store Bailey’s Marshmallow Popcorn to Keep it Fresh?

The best way to store these St. Patrick’s Day popcorn snacks is in an airtight container. If you still have any left after about 2-3 days, wrap them up in plastic wrap, put them in a freezer safe container, and store them in the freezer for up to 6 months.

St. Patrick's Day Marshmallow Popcorn with Bailey's Irish Cream

Serves: 8 Prep Time: Cooking Time:
Nutrition facts: 110 calories 5 grams fat
Rating: 5.0/5
( 2 reviews )


  • 10 cups popcorn
  • 3 Tbsp unsalted butter
  • 8oz (5 cups) mini marshmallows
  • 1/3 cup Bailey's Irish Cream
  • 1/4 tsp salt
  • St. Patrick's Day sprinkles


  1. Prepare popcorn, put in bowl and set aside (see my recipe for the perfect stovetop popcorn here).
  2. Line a baking sheet with parchment paper, or a silicone baking mat. Set aside.
  3. In a medium saucepan, melt butter over medium-low heat.
  4. Once butter has melted, add in marshmallows and Bailey's Irish Cream. Stir mixture until marshmallows are just about melted. Remove from heat and add in salt.
  5. Slowly pour about a third of the marshmallow mixture over the popcorn and gently fold into the popcorn. Continue adding marshmallow mixture a little at a time and folding it into popcorn. Completely cover the popcorn with the marshmallow mixture.
  6. Spray spatula with cooking spray. Pour mixture into prepared baking sheet. Using the spatula, gently press the mixture into an even layer in the baking sheet.
  7. While the mixture is still warm, sprinkle the candy onto the popcorn.
  8. Allow St. Patrick's Day popcorn to cool completely.
  9. Break apart into pieces and enjoy!

Note on Texture: The Bailey's adds extra liquid into the marshmallow mixture, which results in the popcorn being a bit more gooey than regular marshmallow popcorn. I like the texture and the Bailey's flavor is very pronounced, making it extra yummy! If you like a drier popcorn, try adding in less Bailey's (try 2 Tbsp to 1/4 cup) or add in more popcorn (try 12 cups).
