10 Fun and Easy St. Patrick’s Day Cake Ideas


Mar 11

With St. Patrick’s Day around the corner, I thought I’d put together my 10 favorite St. Patrick’s Day Cake Ideas for you. Just hoping to make the creative process a wee-bit easier for you 😉

Rainbow Swirl Cake

First up is my personal favorite: my Rainbow Swirl Cake. If you’ve been here a while, then I know many of you have seen this one. It’s a couple years old, but it continues to be one of the most popular cake designs. So many of you have recreated this cake and I’ve just loved seeing every single one!

I recently made this cake again with Kelly Clarkson on her show, Kelly Clarkson Show. And last year I had the privilege of making it with Savannah Guthrie and Jenna Bush Hager on The Today Show. Both clips will give you tutorials for making this cake, or you can find the full step-by-step picture tutorial HERE.

Lucky Charms Cake

If you’re looking for something a bit more simple, this Lucky Charms Cake is so fun and truly the easiest of the bunch. Since you’re adding Lucky Charms marshmallows over the entire cake, you really don’t have to worry too much about getting your sides totally smooth. Plus, your kids will love helping with this cake. Win win!

Carved Rainbow Cake

Did you catch my video on Instagram for THIS CAKE? I actually did two sides because I couldn’t decide which design I liked best. The first side is this rainbow with sprinkles.

The second side I tried out stripes and clovers.

I think the rainbow side is my favorite, but I truly loved designing both. Do you have a favorite?

Rainbow Dot Cake

Another new one I designed this year was my Lucky Charms-inspired rainbow cake. I love that the rainbows aren’t in traditional rainbow order, but it still screams St. Patrick’s Day with the colors coordinating with our beloved Lucky Charms cereal.

I piped the buttercream around this Green Velvet Cake and then used my scraper to smooth it out.

But the real star of the show isn’t what’s on the outside! It’s what’s on the inside! Using round cookie cutters, I cut holes in two layers of my cake. As I stacked the cake layers, I added gold coins in the empty space. I then continued to frost and decorate the cake, hiding the coins until we cut into it. The kids loved the surprise!

Rainbow Stripes

If you love bold and vibrant colors, this next color palette is for you! I went with very traditional rainbow colors to create this striped cake.

Green Ombre

Or, if you want more green for your St. Patrick’s Day cakes, these next few cakes are for you. First up in this bunch is my ombre cake.

When I’m making my colors for an ombre buttercream, I always start with the darkest shade first. Once I have my darkest color created, I place a bit of the dark buttercream in another bowl and add a bit of white buttercream. Once that’s mixed, I add a scoop of the lighter shade to a third bowl of white buttercream for an even lighter shade.

Four Leaf Clover Cake

My next design is made with a #2 and a #4 Wilton piping tips. You can see in the picture below that the leaves are made by simple swipes and the stem is made with a little line.
