Easy Harry Potter Cake

Harry Potter fans are you ready to make an easy Harry Potter cake? This is the year of cakes in our family. Every other year we do big fun parties with decorations, friends, games and everything. But with super simple cupcakes because who has time for all that and a fun cake? Not this mama. Then on the odd years, we make a really fun cake along with a very simple family dinner and gathering to celebrate.

When my soon to be 7 year old asked for a Harry Potter cake, specifically a Monster Book of Monster cake, I jumped at the chance. This year he started reading the series on his own and loved his Monster Book we did for a Harry Potter party we did last year for his big bro.

To make this easy Harry Potter cake I first started with two rectangular baked cakes (I used my pyrex glass rectangular baking dishes)

My son wanted it to be my favorite double chocolate cake recipe.


Double Chocolate Cake 

1 box Pillsbury Devils Food Cake Mix
4 large eggs
1/2 Cup canola oil
1/2 Cup water
8 oz sour cream
1 small box instant chocolate pudding mix
1 bag mini or regular chocolate chips

Preheat oven to 350 degrees F. In a stand or electric mixer add the cake mix, eggs, oil, water, sour cream, pudding mix and chocolate chips. Beat until well combined, about 1 1/2 minutes. Will be thick. Pour evenly into 2 well greased 9 inch cake pans. Bake for 30-35 minutes or until toothpick comes out clean from center of cakes. Let cool completely.

Time to Start Making

After the cakes were cooled they needed to be leveled. Last year I finally added a cake leveler to my baking supplies. You can also use a knife. Basically, you want to cut off the rounded top.



Not pictured: After leveling your two layers, add frosting to the middle, stack and frost.

Now time for the cut off top leftovers. Use the cut off top and fold it on itself to use as the top rounded eye area of the monster. easy-harry-potter-cake-tutorial-3

Cut a half circle shape out of the doubled over cut off cake top. (note, I only used the top of one of the cakes, the second cut off cake top was for my kiddos to snack on while I worked!)


Put your half circle on top of your cake. The straight edge you will leave alone but using a knife, trim the rounded edges to make it like a hill.


Frost like so.


Now that the base is done, it’s time to start decorating (this is my very favorite part!)

For the ‘pages’ I piped on some white frosting in lines. I used a tip from this set.  I went around three edges with frosting, like pages in a book. Don’t worry about making them look perfect, it is a crazy monster book after all.


I also wanted to show the base. My husband custom cut a piece of wood we had but I have also used cardboard covered in paper or foil, use what you’ve got. I also used a cake turntable to make life easier which was a gift that I have loved using when making cakes.


Now  that the base is done it’s time for the teeth! This teeth were very similar to the way I made clay teeth for our Monster Book of Monsters replica. Just made out of fondant but it could also be made out of gumpaste if you want it harder.


To make the gums you make two thick ‘snakes’ out of red fondant. Then use a round tool from a set I have but you can also use a toothpick, a wooden skewer…..whatever works! These area going to be the gums.


Teeth time. Make up a bunch of small 1/2 inch or so balls out of white fondant. Then start to roll them out letting each end taper off to a point.


One end will go in the hole and the other is the exposed tooth. You can add a small drop of water in each hole to make sure the teeth stick and stay in.


Don’t worry about making sure all the teeth are the same size and shape. It makes it look more interesting and scary!


Curve the ‘gums’ and let them dry for a bit. easy-harry-potter-cake-tutorial-14

While the teeth are drying it’s time to add the eyes and ‘fur’. I looked around and can’t seem to find these specific eyes but there are a ton here. You could also make your own out of fondant.


Before adding the eyes, add some fur using a grass frosting tip and chocolate frosting. Once you have some ‘fur’ on, add the eyes. Then go to town adding fur everywhere. Go back over the eyes and all over the cake. Again, nothing has to be perfect, it is a monster after all.


Once the teeth have dried out a little bit add them to the cake. Mine were a little heavy so I used some toothpicks you can’t see to help hold them in place. Also I made up tounge using a strip of red fondant and making a line down the middle.


This easy Harry Potter cake, Monster Book of Monsters was a hit with Mr. 7 year old! But who wouldn’t love this furry monster?


Also a note I actually had made up an extra layer (I originally though I would need to do 3 layers) so I cut it in half and stacked it to make a mini monster book and used the leftover frosting we had. We ran out of the white and didn’t have enough fondant. He sure was cute though! We had more than enough cake so we sent them up the street to our neighbors who loved him. This just goes to show you can really do any size cake for this that works best for what you have. I bet you could even do cute monster book cupcakes just using ‘fur’, some eyes and if you’re really ambitious some teeth. But I would go simple.


And there you have it, an easy Harry Potter cake, perfect for any of Potterheads out there.
