Spring is just around the corner and I am so looking forward to it! Celebrate Spring by making this easy Spring Rainbow Cake! This is a perfect cake for St. Patrick’s Day too!

You will need:
- Round cake, any flavor
- Light blue frosting
- White frosting
- Red, Orange, Yellow, Green Blue & Purple fondant
- White sugar pearls
- 1/3 cup Light corn syrup
- Wilton flower icing decorations
Frost cake with light blue icing

2. Pipe on clouds with white icing.

3. Melt green candy coating according to package instructions. Pipe green stems onto parchment paper. Let dry completely.

4. Carefully peel the stems off of the parchment paper and place on the side of the cake.

5. Roll out fondant and cut flower shapes using a daisy cookie cutter.

7. Push in sugar pears in the middle of each flower.

8. Cut open a paper towel tube and line with parchment paper. Place fondant flowers in the middle to dry overnight. This gives a nice curve to the flower blossoms.

9. Roll out fondant into long tubes.

Press together the rolls to make a rainbow and let dry for 24 hours.

10. Place flowers on cake. Add some small flower icing decorations too!

11. Place the rainbow on the clouds.
