Cupcake cards are very popular now and they are such fun to make. Look for some nice paper with a cupcake design on it. The best kind is paper with lots of different cakes that are small enough to fit on your cards. That way you can make tons of different cards using the same ingredients.
There are lots of ways to make these cards.
The easiest version is just cutting the whole card out of the printed paper. I did that for the second one from the bottom.
If you feel a bit more like fiddling cut out one of the cakes and glue them to the front of a card. If you use colors that go will together this will look awesome. The third card from the bottom was done this way.
But you can take it one step further and cut out your cake motive two times. So you have two cakes that are the same. If you use a tiny piece of double sided foam tape you can actually make a 3D cake on your card. If you happen to have some Mod Podge Dimensional or some clear nail polish you can paint some parts of your cake like the fruit and make it stand out even more.
The cake at the bottom of the card holder and the chocolate heart card were done this way.
