Lucky Charms Cake Recipe

Last updated on February 11th, 2024 at 09:10 am

I have long been obsessed with Lucky Charms cereal from a very young age. So when I moved to the UK I was sad that they didn’t sell it at first. For the first few years I had my family ship me boxes of the fluffy sugary cereal. I not only ate it for breakfast on occasion but I quite like having a dry bowl of it while watching a movie like my version of popcorn! I was ever so excited when Tescos started selling it on their shelves and I could get it whenever I want. I have made Lucky charm cupcakes in the past but I had an idea for a layered birthday cake using the Lucky charms marshmallows and here my recipe began…Lucky Charms Cake Recipe Birthday Cake

First you get to spent a little bit separating your marshmallows from the wheat cereal into a bowl. I did mind while watching a movie with Mr P. Two birds, one stone and all! I also bought various pastel colored sprinkles to add to the mix. There was no right or wrong way I just used whatever I thought would look nice together. I even added a little edible sprinkle glitter but it didn’t show up to well in my photos. It’s all about variety so you can’t go wrong.

Don’t forget to use your Oxo Good Grips spatulas and measuring beakers just to make it that much easier to get it done right the first time. I am loving the Oxo Good Grips kitchen range with all my baking lately. If you are regular reader you will know I use a variety of their products and I really do think they are 100% worth every penny if you are into your baking and cooking!ย

You don’t have to be a kid to have a love for Lucky Charms clearly and what’s not to love about all the flavors and colors of marshmallow and frosting mixed together. It took all the will power I had to not just eat the whole bowl of separated lucky charm marshmallows.

Directions to put the cake together:

After you have separated your marshmallows cover them and set them aside, then bake your cakes and make your frosting as per my recipe above. Allow your two cakes to cool in the open air and set aside uncovered so the outer edges become stiff. You don’t want to cover your cakes and lock the moisture in because when it’s time to frost them the cake will pull away with the frosting as you try to smooth it out!

Using a cake stand or a plate which ever you choose, place one layer of cake on it and give it a nice thin coat of frosting on top and the sides. Layer your marshmallows flat on top of first layer. I do mind in a circle pattern making sure no marshmallows are on top of each other. See photo at the beginning. You just want one flat layer of them. Use as many or little as you want for your inside layer. If you separated a whole box of Lucky Charms you will have plenty for the top and decorating if you do half the bowl.

Add second layer of cake on top of your marshmallows and GENTLY press down. Add frosting on top and to all sides, really thick, to seal the entire cake. I bought a piping bag for ยฃ3 from Tesco with various tops to use. Using the big star top, I created a star pattern at the bottom where the cake meets the plate and then a mini circle wave on the very top of the cake where I piled on my lucky charms’ marshmallows. You can use whatever pattern you like. I completely made up my stars and waves on mine as I am not very handy with a piping bag yet! Next lesson to learn!

I threw on some sprinkles and edible glitter around the marshmallow center to finish it off and also add a circle of marshmallows on the platter for effect!
