Cut apart a 9×13 inch chocolate chip graham cracker cake then top it with marshmallow frosting to make this adorable S’mores Lamb Cake for Easter, a baby shower, or a farm themed party. Watch the video tutorial to see how easy this is to create.
You all loved the Rainbow Unicorn Cake that I created using one 9 inch by 13 inch sheet cake, that I just had to make another cut-apart cake for you. As I was piping on the the white frosting to cover the unicorn cake my friend suggested that it looked like a woolly little lamb. It did!
With Easter coming up soon and with several of you asking for cute ideas for spring baby showers, I thought it was the perfect time to create a lamb cut-apart cake.
I have such an affinity for baby animals and lambs are just so darn cute, especially the ones with a mix of black and white wool, so that’s how I designed my cake. I’ve always thought sheep look like big marshmallow puffs with legs, so I couldn’t resist topping my cake with marshmallow frosting.
Being I was going to do that, I figured I might as well turn the cake into a s’more cakes.
To keep this cake as simple as possible I started by adding chocolate chips and graham crackers to a doctored white cake mix. Then I blended some marshmallow cream with some Wilton Ready to Use White Icing (affiliate links). I know this cake would taste even better with homemade marshmallow frosting if you want to go through that effort, but I was going for quick and easy and was happy with the result.
To make the black frosting I simply added some cocoa powder and black food coloring to the marshmallow frosting. It tastes great and has a deep black color which looks great on the cake.
Let’s watch the video to see how quickly you can cut and frost one of these cuties.
- I have to admit that I prefer to pipe on my frosting like I did when I made my Unicorn Rainbow Cake, but I know most people prefer to just frost a cake so that’s how I made this S’more Lamb Cake. It looks pretty easy, right?
- You don’t need any special tools to make this cute cake.
- I cut out a cake cardboard into the shape of the lamb just because I wanted to be able to put the cake on various backgrounds for my video and pictures. You can simply place the cake pieces on a rectangle cake board, a serving platter, or even a cutting board. The cake is quite large when laid out so you will need something that is around 14 by 18 inches.
