Monster Cake from Sowdering About in Seattle!

I’m in a FB group for Seattle blogger’s and have met (online anyway) some very talented people, including Randi from Sowdering About in Seattle. When I sew her monster party, I knew it would be a perfect fit for her to join us! I couldn’t decide if I wanted her to share how to she made the cake or the headbands… We decided on the cake! It looks so delicious and I wish I had some now!!!! Be sure to check out her blog and all her fun food ideas and crafts!

Welcome Randi!

My son turned one in January and in celebration, we threw him a “monster” themed birthday party. It was very fitting for him since he is, well,  a monster. 

We had various decor, that was mostly homemade, including but not limited to a pretty awesome cake. I really loved how it came out, it probably was my most favorite thing we had at his party. I thought it would make a great tutorial, so here I am.

Because I baked this cake while we were on vacation in Las Vegas, I didn’t actually take pictures while I made it, so instead, I did what any normal person would do. I made another one. I mean, there is never BAD time for cake right? Lucy decided that she wanted our new monster cake to be a purple cake with red frosting.  I used a basic white cake mix from the store and just added some Wilton’s frosting dye to it.

Once it was all mixed, I cooked the cake according to the directions on the box and when it was done, I froze it.   Freezing the cake turned out to be the best for me because where I had planned to have this cake done in just a couple of days, life got in the way, kids got sick, we got super busy.  Anyway, the cake was frozen so it lasted longer.   When I was ready, I brought the cake out and started frosting it before it was defrosted.  Also, this is where you would normally put on the “crumb layer” of frosting.  This is basically a thin layer of frosting all over the cake which “captures” all the crumbs so that they don’t get tangled up into your top layer of frosting.  I normally do this.  I did not do the crumb layer on this cake.  Not for any particular reason except that I just plain forgot. I mixed the frosting together with Wilton’s frosting dye like I did with the batter.

The recipe I used for the frosting was super easy:
  • 1 cup butter (salted)
  • 4 cups powdered sugar
  • 2-3 tsps vanilla extract (I didn’t measure, just put some in)
  • a splash of whipping cream
Cream the butter and sugar together on low.  Slowly add vanilla and your splash of cream (I left mine a little thicker so I didn’t add a lot of cream).  Mix on med-low until it’s fluffy.  At the end, I added the color and mixed until it was the color I wanted, which ended up being pink, not red.
I noticed with the Wilton’s dye, that if you let it sit a little, it will darken.  So that’s what I did.  After it was all mixed, I let it sit for about 15 minutes.  When I was ready, I pulled out my frosting bag and I used the grass frosting tip that you can get from any craft store.
I always make a HUGE mess when I am frosting.  I will save you from those pictures.  Once my bag was full of pink frosting, I just started piping.  I made small downward strokes to get the “hair” look I was going for.
The best part about this particular style of cake, is that it doesn’t need to be perfect.  It’s actually the imperfections that make it the best.  I mean, what monster have you ever seen with perfectly combed hair?  None.
On Dexter’s cake, I just used large marshmallows on a skewer for the eyes and I used a food marker for the eyes balls.  However, Matt said that we should do something different with this one, so he grabbed some Fruit Loops and we shoved small marshmallows into the holes and then stuck a toothpick in them.  I like how it came out, a little more colorful and fun if you ask me!!
I struggled trying to figure out the best way to cut into this cake to show you the middle.  I didn’t want to just cut into it without a special reason, even though really, Tuesday is a good enough reason to cut into a cake.  But, as it turns out, we were having some friends over for a space craft to celebrate National Space day.  What’s better than a monster cake that you call an alien cake on Space Day right?

Dexter was totally impressed with his cake.  He said it even tasted good with the dirt he had just eaten too.

I thought it turned out pretty amazing.  The colors were great and all the kids loved it.  But what kid doesn’t love a purple cake right?
I hope you all enjoyed this and have fun making your own monster cakes!!!
