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!

How To Make a Fondant Rainbow Topper

Scroll down for the short video below.

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
Extruder
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!
