Here is my trick that works AMAZINGLY well! But, you need a juice extractor. I tried to find one online, and they are hard to find 😦 But, my mom had two, so I just permanently borrowed one.
With no further ado, here is my trick!
Put the juice extractor in, pull it out, and out comes the cupcake! I push the cupcake center out of the juice extractor and then can either pop it in my mouth, OR rip/cut off the bottom half, pop that in your mouth, and save the tops to go back on the cupcakes after you fill them!
I use a piping bag with a small coupler or with a injector tip or something to fill them
Then, you can frost them or top and frost them!
Super easy, if you have the right tool 🙂
