Rainbow Dipped Shamrock Cupcakes are a perfect — and easy — St. Patrick’s Day dessert. A box of cake mix, a box of lime Jello and some rainbow sprinkles and chocolate gold coins for flair! This post contains affiliate links.
Guys, this year has been a vibe. Is eating a million rainbow sprinkles going to fix everything? No. But will it hurt to try? Also no.
This is the same base recipe as my Grinch Cupcakes, basked off my Watermelon Cake and of the combinations I’ve tried, the lime Jello mix that gives it the green color is absolutely my favorite. Something about this flavor combo made it tough to stop eating them and was one of the reasons that my winter coat only technically fit. Technically meaning it did zip, but I had limited mobility. So take these and share the love. They’ll go quick :).
Rainbow Dipped Shamrock Cupcakes How-to
Grab a box of white cake mix and a box of lime Jello. I’ve tried this recipe with a few Jello flavors and the lime is just so delish.
Dump everything in a bowl: cake mix, box of Jello, eggs, oil and water and mix it up for two minutes.
Time to fill the cupcakes
I rarely use cupcake liners because they tear off so much of the cupcake. I want to enjoy every morsel and it’s such a waste. I love Baker’s Joy because you spray it on, nothing sticks and it doesn’t leave a sticky residue. I used liners just for decoration in the final pictures. Can’t get enough flair in my book :). As far as filling the tins, I will say that these batter spoons you’ll see below are so worth it. It’s easy to get every cupcake close to the same size and it’s the easiest way I’ve found. Find them here.
Bake them at 350° for 14-19 minutes.
Time to Frost
So once the cupcakes are completely cool, grab your frosting. I used Pilsbury white frosting. Now you need just a totally slapdash frosting style for this one because the sprinkle application evens anything out. So frost each cupcake.
Put some rainbow sprinkles in a bowl and dip the tops of the cupcakes in the sprinkles until it’s coated. Add some chocolate gold coins for added fun and decorative cupcake liners if you’d like.
There you have it! An easy peasy St. Patrick’s Day dessert in a festive green. And rainbow sprinkles. I think we can all agree rainbow sprinkles make everything at least a tiny bit better :).
