Zest about 1 1/2 lemons to make 1 tablespoon of zest.
Use a lemon juicer to juice the lemons until you have 1/2 cup of lemon juice; about 3-4 lemons, depending on their size.
Prepare cake pan to bake the cake mix.
Bake cake according to the instructions on your cake mix. Substitute 1/2 cup of the water the mix calls for with 1/2 cup of lemon juice. (Some cake mixes call for only 1/2 cup of water. You would just replace all of the water with lemon juice. My mix called for 1 cup of water, so I replaced 1/2 cup of the water with 1/2 cup of lemon juice.) Add the lemon zest at the end.*Important* When adding the zest, add it in a little bit at a time while mixing. It tends to clump together. After you're done mixing, make sure all of the zest is off of the mixer paddle and mixed in. When cake is completely cool, transfer to a large mixing bowl and crumble with your clean hands.
Make sure there are no large lumps of cake left in the bowl and it is completely crumbled.
Add 3-4 tablespoons of lemon frosting to the cake. (You want to add enough of the frosting so the cake sticks together.)
Start mixing in the frosting with a large fork.
Finish mixing the cake and the frosting with your clean hands until fully incorporated and no longer crumbly.
Line two cookie sheets with parchment or waxed paper.
Make a large cake ball with your hands that is a little bigger than the cake ball former.
If you don't have a cake pop former, not to worry. You can roll the balls with your hands. If you want the cake pops to be uniform in size, you can use a cookie scoop or a tablespoon measuring spoon to measure out the cake balls.
Put the ball into the former. You want it to be bigger than the former.
Squeeze the cake pop former together.
Remove the extra cake from around the former.
Open cake pop former and place pop on the cookie sheet.
Repeat making pops in the former until all of the cake is gone, placing each one on the prepared cookie sheets.
Freeze cake pops for 15 minutes.
Add candy melts and vegetable shortening to a large, glass measuring cup, or a deep microwave-safe bowl. You can also use a large, tall microwave-safe glass.
Melt candy and vegetable shortening in the microwave for 20-second increments until completely melted. Stir in between each 20-minute increment.
Remove the cake pops from the freezer. Transfer the cake pops to the refrigerator and leave out 5-10 for dipping at a time.
Start by taking a lollipop stick and dipping it about 1/2-inch into the melted candy.
Insert stick halfway into the cake pop.
Lower cake pop all the way into the melted candy in one motion and then pull up. You do not want to dip more than once. If there is too much candy on the pops, they may be too heavy and come off of the stick.It's important to add the vegetable shortening when melting the candy because it thins out the candy so it isn't too thick. After pulling the cake pop out of the melted candy, you're going to tap the wrist that is holding the cake pop to remove the excess melted candy. Tap until a lot of the candy has come off.
Continue to hold the cake pop over the candy bowl until you see that it has almost stopped dripping. I usually count 30-60 seconds.
The cake pop is ready to decorate.
Hold cake pop over the nonpareils or sprinkles and add a little bit at a time with your fingers until decorated the way you want it.
Place decorated cake pop onto a cake pop stand or a styrofoam block.
Continue dipping cake pops and decorating until finished.
Let the cake pops dry for about 1 hour before serving or storing.
Serve and enjoy!
