Warning: It’ll Be Messy. You’ll Make Mistakes. Probably.

With the idea of making a slime cake, it would only be natural to infer it’d be messy. Consider the composition of actual slime. The vivid green liquidity substance that oozes and spreads. When blasted, its victims are covered completely in green.

We were too excited to relive an aspect of our childhoods that we completely ignored those minute details… and quite a few others in the recipe. Baking a cake can be relatively messy, but a slime cake is at another level.

We dug up whatever we had in our pantries and also used Ramen noodle budget affordable products you could find at your local Aldi or Dollar Tree.

FYI, for the tl;dr people, you can skip to here.

What you’ll need:

1 box Duncan Hines Classic Yellow cake mix

8-inch round cake pans (2)

2 boxes of vanilla instant pudding


Vegetable Oil

Pam cooking spray (to line the pans if they aren’t nonstick)


Betty Crocker Classic green gel food coloring

Chilled heavy cream



2 large Ziploc bags


Lots of paper towels

Large serving dish or cake stand


Baking the Cake

Prepare your supplies. Lay out everything needed to make boxed cake mix. Tip: a good ol’ fork or large spoon will do in place of a whisk.

This is actually the easy part. Just follow the instructions on the Duncan cake box to make the 2 cake layers. Keep watch of the oven so the cake doesn’t burn.

Pudding Slime

According to the slime cake recipe in Nickelodeon Magazine, preparing the green slime is the next step. We had to make a few guesses with some of the measurements. We made the pudding mixture according to the directions on the box and reduced the amount of pudding mix by using about 1 ½ boxes instead.

The pudding making portion reminded us of Stu from Rugrats. It also made us question why so many anime characters cry for pudding. ?

We made the mistake of placing the pudding in the fridge without adding the food coloring, which was supposed to be added while blending the other pudding ingredients. Not to worry though, we weren’t too deep into the process that we couldn’t go back a step. Of course, this wasn’t the last of the roadblocks we encountered though.

Supposedly 8-12 green drops of food coloring are required to get that iconic lime green shade, but FYI it’s a straight up lie. Tip: Be sure to modify the number of green drops if you plan on making this beast. 18 drops or so worked pretty well for us.

Food coloring during the ‘90s was probably different then. Many dyes have been reviewed and delisted throughout the years due to safety concerns and a variety of other reasons. The concentration may be less now. Society’s mindset toward color and food additives have changed as well. Think about it, would words like organic, gluten-free, free-range or grass-fed have been uttered in the ‘90s? Yeah, we didn’t think so.

This step really should have been done before baking the cake. The pudding has to chill in the refrigerator for at least an hour. While the cakes bake, the pudding could chill around the same time.

The process is extensive and slightly frustrating. Perhaps it’s because we’re hopeless at baking and following instructions. Nevertheless, we recommend having something playing in the background to keep your spirits up.

Our source of entertainment as the cake baked was the Rapunzel Before Ever After special on Disney Channel (much to Fox’s chagrin). During the breaks we saw the commercial for Disney’s then upcoming series Andi Mack. Honey had already seen the promos and wanted to see if Fox would have the same reaction.

In case you were wondering what the hubbub is about:

“You see it right?” Honey asked.

“So that’s her..,” Fox began. Without skipping a beat Fox researched the series online and soon we were watching the first episode exclusive. Andi Mack is different from the trash Disney Channel usually spits out (e.g Girl Meets World) and has bit of a Lizzie McGuire feel. If that doesn’t catch your interest, your best bet is something on Netflix. Our go-to favorite is Bob’s Burgers.

The Filling

The baking had to be put on pause as a replacement carton of heavy cream was fetched from the store (along with a Popeye’s chicken drive by). Tbh the recipe called for so many ingredients, we were bound to forget something during the commute.

This time we did not forget the green food coloring as we combined the a carton of chilled heavy cream, sugar, and vanilla. A tub of whipped cream would have probably worked just as well, but going by the book seemed much more fulfilling to us- at least for making the whipped cream. Again, more than 12 drops of green food coloring were necessary.

Yet when it was time to whisk the mixture we were at a standstill. There was no whisk in sight. It’s at these moments you make do the only way you can: with a fork and arm as powerful as any machine. Tip: Be sure not to scrape the bottom of the mixing bowl as you “whip” or else you’ll be spending a long time whipping the cream. Use the fork to fluff the mixture.

No judgement. Housing proper kitchen tools was never a priority of ours.

Have you ever encountered weird whisk alternatives? For Honey being introduced to an actual whisk happened in a home economics class and was a mind blowing experience. Fox happened to win a rotary egg beater at an elementary school carnival. Although nifty, the gadget is a bitch to clean and pinches your fingers. Fox went on to own an electric mix later in life. Sadly, the mixer had been rightfully owned stolen by a sibling and is now beyond reach. If you have mixer money, treat yo self!

After you finish whipping the cream into soft peaks, scoop it into a Ziploc bag. Twist and seal to create a pastry bag. This will give you a better handle on spreading the filling onto the cake.

Layering the Cake

Carefully flip a cake layer onto the serving dish. Cut a small slit into a corner of the bag, then perform a squeeze dance over the layer. We spelled out “Honey and Fox” for funsies before spreading the filling.

The filling was excessive, but we didn’t want it to go to waste so we piled it on and continued stacking the cake.

Sliming the Cake

The fun yet extremely messy part- getting the pudding in a Ziploc bag and letting the slime flow.

Recipe Notes

From the lessons we've learned from our own experience, we're straying from the recipe order and suggest making the slime first due to the minimum 1 hour chill period.

Our reaction to the moment we completed the slime cake:

Don’t be fooled by the sweet slime cake shots in Nickelodeon Magazine. Making a slime cake is a lot of work. We started around 7pm and ended by midnight. Even though we took a foodie break, watched a show, lost an hour due to foolishness, it was still time consuming.
