So what could top an Instructables holiday meal but an Upside-down Pineapple RoboCake? Make individual serving size cakes to enjoy when winding down for a special treat after the guests have gone or just make one big family size one to share with everyone.

Traditionally, upside down cakes are made in a cast iron pan. Since we want a special shape, you will need to break out your Instructables Robot Robo-form which will mold the cake. You can also make this with the Hello Kitty form which would be purrr-fect for your feline fanatics.

Step 1: Get Ready...

Since you spent all day preparing the other parts of the meal for your guests, dessert should be quick and easy. I will take the shortcut here and use prepared ingredients but if you had the time and inclination, please make everything from scratch.

You will need:

- Box of cake mix (any kind, white, yellow, sponge, chocolate, marble, etc.)

- Can of sliced pineapples in syrup ( you can substitute any kind of sliced fruit, canned or fresh)

- A couple of pats of butter

- A bit of brown sugar, any kind of regular sugar will work if brown sugar is not in the cupboard. You will have a richer color and flavor if brown sugar is used.

- Robo-form "pan" (Robo-form with an aluminum foil bottom)

- Heavy cookie sheet or cast iron pan to fit your Robo-form

Don't have an Instructables Robot Robo-form or Hello Kitty-form, make one:

small custom forms
or
larger custom cake pans.

Step 2: Pan It Out. Butter It Up...

I don't really measure in my cooking as I do more things according to taste. In our family we don't really have a sweet tooth so things are not overly sweet as preferred by many.

Heat your oven up to 350 degrees F.

Form the bottom of your improvised spring form pan by adding a bottom with aluminum foil and wrapping the excess over the top edges of the form. Crimp the bottom to the edge to ensure a leakproof seal. Place this on you cookie sheet or cast iron pan to put in the oven. The heat from the cookie sheet or cast iron pan will help brown the bottom of the cake.

Place a few pats of butter in the bottom of the form. You want a layer of decadent fat for the pineapple or fruit to bathe and sear in the bottom and sides of the pan. Place in the oven for a bit to melt the butta.

If you are doing the smaller size cake, you can throw this in the toaster oven for a minute or two. Just do a toast cycle until you hear the butter start to pop.

WARNING: Don't do this in the microwave, severe damage and danger when placing metal objects for use in microwave oven.

Step 3: Pineapple Bottom Top...

When the butter has melted, remove from oven. Turn the form so you can coat the sides of the form. You can now sprinkle with a bit of brown sugar all over which will make a nice glaze for the fruit.

Drain the syrup from the can of pineapple but save it to add some to the cake mix.

Layer the bottom with the pineapple slices. You can also stand a few pieces on the sides.

If desired, you can throw in a few garnish items for color such as maraschino cherries.

Step 4: Batter Down...

Prepare your favorite cake recipe. I just followed directions on the box but substitute some of the liquid required with the syrup from the can to add flavor and sweetness.

Follow the box directions to bake the cake. Test for doneness by sticking a toothpick or wooden skewer in the center of the cake. If it comes out clean, the cake should be ready. Adjust your baking time for the size of the cake. The cake should also be browned a bit and the sides separated from the sides of the pan.

Let the cake rest for about 15 minutes after it comes out of the oven. This will let the cake absorb any excess juices on the bottom.

You may need to help your cake separate from the sides of the pan by scraping or sawing down the sides with a wooden skewer or thin knife.

Place a large serving platter over the top of the form. With a good grip on the platter and the cake, flip the entire assembly over. Remove the form. You cake will now be upside down with the bottom being the top.

Step 5: Yum, Yum, Yum...

This should be served warm and if desired, with whipped cream or ice cream on the side. Add a nice hot or cold beverage to wash it down.

Happy holidays and may you enjoy the company of good friends, good family and good eats.
