Bake cupcakes according to the box instructions and let them cool completely before decorating.
15.25 ounces yellow cake mix
Melt cocoa candy melts in the microwave for one minute, stirring after each 15 second interval. Continue until they're melted and smooth, then dip pretzels 3/4 of the way into the chocolate one by one. Allow them to dry slightly before placing them on parchment paper. Pour leftover chocolate into a piping bag and cut off a small tip.
1/2 cup Light Cocoa candy melts, 24 pretzel sticks
Holding the pretzel, drizzle chocolate over it in a back and forth motion. Lay them on parchment paper and allow them to set completely.
For the palm leaves, melt down your dark green candy melts the same way and add to a piping bag. Lay out a piece of parchment paper and pipe palm trees leaves on top, creating 3 leaves on each side. Sprinkle immediately with sanding sugar and let harden completely.
1 cup dark green candy melts, dark green sanding sugar
Lay a piece of plastic wrap on your work surface. Pipe a line of blue frosting and white frosting on top of the plastic wrap, then roll it up.
16 ounces white frosting
Cut one end off the wrap. Then, drop the open end down into a piping bag fitted with a 1M tip.
Starting in the center and working your way out, pipe frosting on top of each cupcake.
Remove your palm tree leaves from the parchment paper and dab some chocolate on the back. Stick to the top of your pretzel "tree trunk" and hold until set.
Sprinkle half the cupcake with crushed graham crackers. Lay the edible flowers on top of your graham cracker sand, then add a palm tree..
Serve and enjoy.
Notes
Don't have graham crackers? You could also use crushed Nilla Wafers or Golden Oreos for the sand.
