Well, I first saw these "cake push ups" just a few weeks ago. A member on our site mentioned them & I thought that this idea was pure genius! Three cheers for a new way to eat cake! :0) --
Basically, a very smart person (I don't know who you are!) figured out that push ups are not just great to use with ice cream---but with cake too!
The good news is that you can order these push ups and make cake push ups for you and all of your friends! A quick Google search will give you numerous online suppliers of these cute containers--I've even seem them in local craft stores that carry cake supplies.
Here's how you make them! --
Simply use a circle cutter of a similar size to your container to cut out little cake rounds from a cake layer or two.
Experiment with your favorite flavor combinations.... I'm using strawberry & whipped cream here, but I also used vanilla buttercream, mint buttercream, chocolate chips, Andes mints, jimmies, sprinkles, & even a mock "mousse" made with vanilla pudding and whipping cream ....
I made some cute little chocolate toppers that I piped with melted chocolate bark... but they would have been cute also with just a swirl of icing! 
Finding a way to display these is a little tricky. We used a circle of styrofoam which we wrapped with a brown ribbon (double sided tape) and covered with chocolate chips!
And the big finish!!! 
You can see that I experimented with lots of different flavor combinations! The cake push ups do have lids, and so if you need to travel with them, you can attach the lids and do your final toppers before party time! All in all, this little novelty is a lot of fun. I did find out after launching a few strawberries across the counter that you really should "push up" gently! :0) -- But once I figured that out, it was smooth sailing....and now I am full of cake! --

That's all for now! Thanks for stopping by the blog today....and if you have any fun ideas for me to try, send me an e-mail!! :0)
I live on the Ontario-Quebec border and purchased them in Walmart in both an Ontario and a Quebec store. They are where the cake decorations and cake pans are in the store. Cost is $4.00 plus tax for 2 in a package. Someone told me thay can also be purchased at MICHAELS but I think are a bit more expensive. I believe Wilton may also make them. Grace
Thanks Grace, yes-- I've seen them at our Michael's too! This post is a few years old and they used to be so much harder to find. Thankfully you don't have to buy them in bulk anymore like you used to. Thanks for the head's up about Walmart!
