I looked all over the net for ideas and possible tutorials. For many, I would need a shaped cake pan, which by the time I decided to do the frog theme, it was too late and I didn't have the money for it anyways. And I would have had to get it online, which I waited til Friday to let my mom know what I needed to make it.
I found one that sounds great and pretty easy. I ended up making it my own kind of. I just got two white cake mixes and store bought buttercream icing. The tutorial said I needed a 8in square cake, and 9in round one and two cupcakes. As I said before, I waited to long. I realized I only had one thing, the cupcake pan. I ended up using a rectangle pan instead of square. And also used my springform pan for the round one. Which was a great idea.
So pretty much just bake the mixes as stated, or if by scratch do that. Make sure to make the 3 size cakes you need.
I put it in the fridge for the night, because lately, I can't just get rid of these fruit flies. They are few now though luckily.
I frosted it the next morning, just took and frosted the top of the cupcakes in white, then mixed up most of what was left and made that a limeish green, which I later used for spots.I used what I had left from that and the other can to make a darker green. Then I frosted it, and it actually turned out nice and smooth, better than any other time I have ever done so.
Then I just used M&Ms, KISS ones at that, to make the eyes and mouth.
ETA: I realized that I never actually explained how to go about doing the cake. Once the cakes have cooled, you will want to take the square/rectangle one and cut it to make the legs and feet. You can see that the one foot looks a bit bigger, I cut that one too close and it came apart when I moved it. So, I had to try and get it in there just right. Which didn't go the greatest.
After cutting the legs/feet, you pretty much just frost the pieces and put them together. I frosted the cupcakes first, then the body, then the legs.
That is pretty much it.
