Bake the vanilla cake according to the package instructions and let it cool completely. Once cooled, remove the darker edges/corners if preferred for an even color.
Crumble the cake into fine crumbs in a large bowl.
To prepare the buttercream frosting, add room temperature butter, powdered sugar, and vanilla extract to a mixing bowl. Beat using a hand mixer for about 2–3 minutes on low to medium speed.
Add the frosting gradually to the cake crumbs in batches (REFER NOTES). Adjust quantity of frosting accordingly. Mix until the crumbs come together and you can form smooth balls.
Use a icecream scoop to measure small portion of the mixture. This is to ensure even sized cake pops
Use your hand to shape and smooth the mixture into small balls and place them on a tray. Freeze the cake balls for about 30 minutes.
Meanwhile, melt the candy melts according to package instructions.
After chilling, roll the cake balls again gently to smooth and perfect their shape.
Dip the tip of each lollipop stick into melted candy melts and insert it into the cake balls. This helps the sticks stay in place. Dip each cake pop into the melted candy coating.
Tap gently to remove excess coating. Immediately sprinkle decorations over the coated cake pops.
Place the cake pops in a lollipop stand or on a plate lined with parchment paper to dry.
Store the cake pops in the refrigerator and enjoy
