Half Birthday Cake: 8-layer Starlight Yellow with Strawberry Filling

I made this cake this morning for Leyna's half birthday. It was SO GOOD. My only regret is that I didn't make my own icing because the store bought kind is super sweet.
For the cake I used my standard birthday cake recipe found here, and baked two 9 inch round cakes. After they cooled I stacked them and cut them in half straight down so I ended up with 4 half circles. I then cut each half circle in half horizontally to make it half as thick. I could use a little practice on this step - they weren't quite straight. Next I put some icing on my cake stand and set the first layer on top. I then alternated cake and strawberry jam layers (I used Costco's Organic Strawberry Jam) until they were all stacked, flipping the layers this way and that so that if the cake was lopsided I could put the thinner or thicker side of the next layer to adjust it. Does that make sense? I finished it all off with white icing from a jar but I wish I had used homemade buttercream. I also need lots of practice on my cake icing skills. Crumbs everywhere!
I meant to finish the whole thing off with sliced strawberries right before we ate it but I forgot. Oops. It was delicious anyway and I'll be making this again FOR SURE!!!
