Preheat the oven to 350 degrees.

Prepare your 3D Skull cake pan using coconut oil and flour to keep the cake from sticking. Make sure to cover generously, so nothing sticks to the pan. Set aside for later.

In a medium bowl, cream sugar and butter; beat in eggs; add vanilla; and mix all together. Add flour and baking powder and mix. Add milk and mix completely.

Fill each of the skulls in the pan about 3/4 of the way full.

Bake for about 30 minutes or until toothpick done.

Remove it from the oven and allow it to cool.

Once the cake has cooled, you should be able to just dump the skull cakes out.

How to Make Candy Stuffed Sugar Skulls:

Start trimming the cake skulls so they fit together nicely.

Use a spoon to dig out a hole in the back of the skull's head for the candy. If you want to include more candy, you can increase the size of the whole thing by using the front of the skull too. Just to make sure everything lines up.

Load your skull up with NERDS® Fun Size Candy, NESTLÉ® BUTTERFINGER® Fun Size Candy, or NESTLÉ® CRUNCH® Fun Size Candy. I found that when adding NERDS®, it was easier and more fun for everyone if I opened the box and poured them in. The Fun Size NESTLÉ® BUTTERFINGER® and NESTLÉ® CRUNCH® fit great!

Use an edible adhesive to glue the front and back of the skulls together and allow them to dry thoroughly.

If needed, trim the tops of the skulls so they are even, and add extra adhesive if needed.

Roll out a small strip of fondant and lay it over the top of the skull to cover the gap where you glued the skulls together. It will help to hide the gap when you cover the skulls in fondant.

Roll out your fondant. I found it easiest to roll it into a thin circle.

Sit the skull in an upright position and lay the fondant on top of the skull so you can work down using your fondant tools. Working with Fondant takes some practice; as you can see, my sister and I are nowhere near pro status, but one day maybe. In the meantime, it's super fun to learn.

Draw the mouths using your edible markers, and color the eyes if you choose to go that route. My sister and I found it easiest to start with the mouths and coloring in the eyes. We tried to get ahead of ourselves and start adding all the fun bright colors and things, but ended up taking them off to draw on the mouth and color in the eyes.

Now it's time for the fun part, where you can get creative! Using your edible markers and fondant tools, decorate your Day of the Dead Skulls however you like.

Most importantly, have fun, and if you’re not sure what the sugar skull represents, I suggest reading about it before making your own sugar skulls; it might influence the direction you choose to go.
