Ingredients for Rat Cake Silly Cake
Here’s everything you’ll need to bring this mischievous little rat to life – and yes, I’ve learned the hard way that substitutions can lead to some very un-rat-like results!
- 2 cups all-purpose flour – spooned and leveled, please! Packing it gives you a dense rat nobody wants to eat
- 1 cup granulated sugar – regular white sugar works best for that perfect crumb
- 1 tsp baking powder – fresh is key, test it if yours has been sitting awhile
- 1/2 tsp salt – just enough to balance the sweetness
- 1/2 cup softened butter – leave it out for 30 minutes until it gives slightly when pressed
- 2 large eggs – room temperature helps them incorporate better
- 1 tsp vanilla extract – the good stuff, not imitation!
- 1/2 cup whole milk – the fat content makes for a richer rat
- Black gel food coloring – liquid works in a pinch, but gel gives that perfect gray rodent hue
- 1 cup chocolate frosting – homemade or store-bought, no judgment here
- 2 marshmallows – for those beady little eyes (mini ones work great)
- Black licorice strings – about 6 thin pieces for proper whiskers
Pro tip: If you can’t find black gel coloring, mix equal parts red, blue and green food coloring – it creates a surprisingly good gray base! For more baking tips, check out these baking tips.

Equipment You’ll Need
Don’t worry – you don’t need fancy equipment to make our mischievous rat cake! Here’s what I always grab from my kitchen:
- Rat-shaped cake pan – the star of the show! Mine’s a 9-inch silicone mold I found online
- Large mixing bowl – for all that batter mixing action
- Whisk and spatula – my trusty sidekicks for smooth batter
- Cake tester or toothpicks – gotta check if our rat is done without burning his little feet
No rat pan? No problem! Use a regular round pan and shape the ears/tail with extra batter or frosting. I’ve even seen people use a loaf pan turned sideways – get creative!
If you’re in the mood for something more elegant but equally unforgettable, don’t miss the rich and creamy Basque Burnt Cheesecake—a caramelized masterpiece that’s just as bold in flavor as it is in appearance.
How to Make Rat Cake Silly Cake
Alright, let’s bring this mischievous little guy to life! I promise it’s easier than it looks – just follow these steps and you’ll have everyone squealing with delight (in a good way).
Preparing the Batter
First things first – preheat that oven to 350°F. Now, grab your biggest mixing bowl and let’s make magic happen. Whisk together all your dry ingredients – that’s the flour, sugar, baking powder, and salt. Don’t just dump and stir – take an extra 30 seconds to really whisk out any flour lumps. Trust me, your future self will thank you when that batter turns out silky smooth.
In goes the softened butter – I like to cut it into chunks first so it incorporates easier. Use your mixer (or some serious elbow grease) until it looks like coarse sand. Now the fun part – crack in those eggs one at a time, then pour in the vanilla and milk. Mix just until combined, no more! Overmixed batter makes for tough rats.
Time for the transformation! Add your black gel food coloring a little at a time – I start with about half a teaspoon. The batter should be a dark, moody gray, not quite black. Too light and your rat will look washed out, too dark and you’ll lose those cute details in the pan.
Baking and Shaping
Now, grease that rat pan like its life depends on it – I use butter and a light dusting of flour, making sure to get in all those little ear crevices. Pour in your beautiful gray batter, smoothing the top gently with a spatula. Pop it in the oven and set your timer for 25 minutes – but don’t wander off!
The perfect rat cake should spring back lightly when touched and a toothpick should come out with just a few moist crumbs. Overbake it and your rat will be dry as the desert – we want him moist and slightly fudgy! Let him cool in the pan for 10 minutes (patience!), then carefully turn him out onto a rack to cool completely. Trying to frost a warm rat is a recipe for disaster – trust me, I’ve made that mistake!
Decorating Your Rat Cake
Time for our rat to get his personality! Spread that chocolate frosting generously – I like to start with a thin crumb coat first to catch any loose crumbs. Then go wild with the rest, making sure to define those ears and tail. For the eyes, snip mini marshmallows in half and press them gently into place – they’ll look wonderfully beady. Finally, take your licorice whiskers and insert them with tweezers (or clean fingers) at a jaunty angle. Step back and admire your handiwork – you’ve just created the most delightfully disgusting dessert on the block!

Tips for the Perfect Rat Cake Silly Cake
After making more rat cakes than I’d care to admit (okay, maybe I’m a little obsessed), I’ve picked up some tricks that make all the difference:
- Gel food coloring is your best friend – liquid dyes water down the batter, but gel gives that perfect eerie gray without changing the texture
- Chill your cake before frosting – 30 minutes in the fridge firms it up so you don’t get crumbs in your chocolate fur
- Tweezers for whiskers – clean eyebrow tweezers let you place those licorice strings just right without smudging frosting everywhere
- Bake a test tail – pour extra batter in a greased spoon to make a removable tail you can position perfectly after frosting
Remember – the messier he looks, the more realistic (and hilarious) your rat cake becomes!
Variations and Substitutions
Who says rats can’t have makeovers? Here are my favorite ways to mix things up when I’m feeling fancy (or just ran out of ingredients!):
- Frosting switcheroo: Vanilla frosting with cocoa powder makes a great chocolate substitute, or go wild with peanut butter frosting for a “nutty rat”
- Eyes that pop: No marshmallows? Candy eyeballs work perfectly, or pipe white frosting dots with chocolate chip pupils
- Color experiments: Pink rats for Valentine’s Day, green for St. Patrick’s – just adjust your food coloring!
- Dietary tweaks: Almond milk works beautifully, and gluten-free flour blends can substitute cup-for-cup (just add 1/4 tsp xanthan gum)
My motto? There’s no wrong way to make a rat cake – just delicious new possibilities! For more dessert ideas, explore these desserts and sweets.
Serving and Storing Rat Cake Silly Cake
This little guy is best served at room temperature – the flavors really pop, and the texture stays perfectly moist. I like to present him on a plain white plate so all his ratty details shine (bonus points for adding a wedge of cheese prop!). If you have leftovers (which is rare in my house!), pop them in an airtight container. He’ll stay fresh for about 3 days at room temp or up to a week in the fridge. For longer storage, wrap individual slices tightly in plastic wrap and freeze for up to 3 months – just thaw at room temperature when those rat cravings strike again!
Nutritional Information
Now, I’m no nutritionist, but here’s the scoop on our mischievous little rat cake: Each slice packs about 250 calories with that perfect balance of sweetness and richness we all love. Remember, these are just estimates – your actual results might vary depending on ingredient brands and how generous you are with that chocolate frosting!

Frequently Asked Questions
Over the years, I’ve gotten all sorts of questions about this delightfully weird cake – here are the ones that pop up most often from fellow rat cake enthusiasts!
Can I make this without a rat-shaped pan?
Absolutely! A regular round pan works fine – just use extra batter or frosting to shape ears and a tail. I’ve even seen creative bakers use a loaf pan sideways to form the body.
Help! My frosting is too runny – how do I fix it?
Been there! Pop it in the fridge for 15 minutes to firm up. Too far gone? Mix in a tablespoon of powdered sugar at a time until it thickens. Works like a charm!
Is there a vegan version of rat cake?
You bet! Substitute the eggs with flax eggs, use plant-based butter and milk, and check your food coloring is vegan. The marshmallows will need replacing too – try vegan marshmallows or white chocolate chips.
Can I make this cake ahead of time?
Totally! Bake it up to 2 days in advance – just wrap tightly and frost day-of. The unfrosted cake actually freezes beautifully for up to 3 months!
