St Patricks Day Guinness Cupcakes are So Cute and tasty with mint buttercream frosting. Make these for your Rainbow Holiday Party! Kids Love them and So do grown ups.
Okay folks! St. Patricks day is coming up so it’s time to get moving in the kitchen! I absolutely love to make cupcakes as festive as I can. I make my whole family groan whenever a holiday comes around because I’m running around the house like a lunatic putting up decorations.
It’s so fun having little themed decorations and food around holidays! I can’t help myself. I have a decoration addiction, much like my flower addiction if you have read any of my previous cupcake posts.
I get energized creating little cute things! Like these St Patricks Day Guinness cupcakes.
The actual chocolate cupcakes are so enhanced by the addition of Guinness. They have an added depth of flavor. A deep rich chocolate flavor. The texture is tender, moist and holds together well.
The mint Buttercream frosting makes an excellent counterpoint to the chocolate. The result is one outstanding cupcake. Perfectly themed for St Paddy’s Day.
Homemade is all about limiting the amount of chemicals in our diets. And being creative. Watch how I compare the colors and textures of working with Natural Vs. Artificial Food Dyes. We were Shocked at the results!
I got so excited about baking for St Patrick’s Day I actually made two versions of my Chocolate guinness cupcake.
The cake recipe and frosting are the same. The decorating are VERY different. So I split up the posts. This way it’s less confusing for you to read.
The rainbow St Patricks Day Cupcake is pictured below. That was a bunch of fun to make. So easy too. I have directions in the post for how the frosting is done if you are interested. Pop over and take a look.
These Adorable solid Green cupcakes I decorated with a rainbow airhead (affiliate link) candy strip, little star clouds made out of white frosting, and a gold Rollo (or gold coin) candy to top it off!
Guinness Cupcakes are SO rich and delicious. Kids love them!
