Surprise-Inside Cake with a Rainbow Heart

If you tuned in last Saturday, then you know I took the Surprise-Inside Cakes class on Craftsy from Amanda Rettke of I Am Baker to learn how to make her signature surprise-inside heart cake. Well, here is the reveal with an Easter spin on it.

As mentioned before, not perfect but a good start for my first time.

I used box cake mix as Amanda recommended, and chilled it, but I think next time I will use a heavier crumbed cake that’s closer to a pound cake crumb to prevent it from crumbling while carving. Other than that, this is such a fun cake to make and people love it! And if you haven’t noticed, I’m still on my pastel kick, but it’s appropriate for an Easter dessert.

The only recipe I have for you today, is my new Vanilla Malt Buttercream. It’s incredibly easy to make and of course, deliciously awesome.

Don’t forget, the giveaway for this Craftsy class with Amanda is still going on, so hit the jump here to enter.

      Skye – I have to admit, yes it was. It’s definitely something you want to make in steps.
