HOW To Make A Fun St. Patrick’s Cake
- Bake your favorite recipe using the 6-inch cake pans. I used the vanilla cake recipe that my friend Blair did; click here.
- Let the cake cool for 10 minutes, then take the cake out of the pan.
- Cut the top using a serrated knife or a cake lever if there is a significant dome.
- Make your favorite buttercream and set aside a small batch of buttercream for the green color.
- Whiten the buttercream using white food gel coloring.
- Fill and Crumb coat the cake with buttercream covering all the bare spots.
- Please put it in the fridge for 10 minutes.
- Fill one disposable piping bag and cut off a snip large enough to pipe.
- Pipe in rows working the way bottom to the top.
- Use the cake topper comb to smooth the buttercream, but not too much since you will be using the stripe cake comb to create lines.
- Use the stripe cake comb to create the lines. Heat the scraper as needed. The key is to have apparent indents.
- Put the cake in the fridge for 15 minutes.
- Tint buttercream green.
- Fill a disposable bag with green buttercream.
- Fill the lines with the green buttercream.
- Use the cake comb to scrape off the green. Slowly scrape until you no longer see muddy lines. Fill in the lines as needed.
- Scrape off the top with a knife for a clean edge.
- Apply the sprinkle clovers (from the sprinkle blend, or you can google it to find stand-alone sprinkle clovers)
- Sprinkle on the sprinkles on the bottom of the cake.
- Put the fondant rainbow topper on the top of the cake.
- Pipe “clouds” using the 2A piping tip.
- Sprinkle on the sprinkles on the top.
- Enjoy the cake!

Fondant Rainbow Supplies
I like Satin Ice for my fondant needs, but other brands work fine.
- Red Fondant
- Orange Fondant
- Yellow Fondant
- Green Fondant
- Blue Fondant
- Purple Fondant
- Circle Cookie Cutter
- Piping Gel or Edible Glue
- Fancy Sprinkles Edible Glitter: (CAKEINSPO15 for a discount. Make sure the glitter is EDIBLE when purchasing from Amazon.)
Fondant Rainbow Topper Instructions
- Grab a ball from purple fondant.
- Warm it up for 3-5 seconds to soft and pliable. The extruder works better when the fondant is smooth.
- Use a small hole setting for the extruder.
- Put the fondant in the extruder and push it out.
- Please put it on the top of the circle cookie cutter.
- Repeat the steps with the rest of the colors except two that you want to do a rope texture.
- Switch the small hole to a smaller hole for the two colors you want to do a rope texture.
- Do two for each color.
- Twist the same color to make it into a rope border.
- Assemble the rainbow by putting the colors in the correct order.
- Use an edible glue or piping gel between each color and gently press down to attach each color.
- Once all colors are attached, cut off the edges by using an Exacto knife or a scraper.
- Leave it to dry for at least 24-48 hours.
- Affix a bamboo skewer on the back of the fondant rainbow by using a little melted chocolate on both sides.
- Brush the fondant rainbow with some edible glitter.
- Gently attach the fondant rainbow to the cake.
- Enjoy the cake!
