Terrarium Cake

Posted on March 05 2012

I can't contain my excitement about this cake, how totally fun it is! I myself don't own a terrarium because I cannot be trusted to keep any plant alive, but I think terrariums are so cool. I've noticed how popular they are recently, so when we got these chocolate crunchies in I knew a terrarium cake must be made!

I filled my terrarium jar with chocolate cake batter about 1 inch deep, set the whole jar on a cookie sheet, and baked. I was a little nervous about baking in something not labeled for baking, but it worked beautifully! Please bake at your own risk though.

After cooling I poured in some chocolate crunchies, enough to resemble a nice layer of top soil. I then tinted decorator frosting with a 50/50 mix of leaf green and forest green gel paste coloring and filled my frosting bag fitted with a round cupcake frosting tip. I generously pipped in blobs and swirls of frosting and sprinkled with green non-pareils for a mossy feel.

Then I tucked in some candy rocks here and there and topped with 2 totally cute chocolate mushroom lollipops. Learn to make the mushrooms here.

I just love how this cake turned out and how really very simple it was to put together. I love projects like that!

    Hi Farah! We used a large serving spoon and just scooped it out. We served a large spoonful of cake along with scoops of ice cream in bowls. Thanks for reading!

    If you are concerned about baking in a glass jar, try a recipe for microwave cake, available on the internet. For individual terrariums, look for a microwave cake in a mug recipe.
