During the early days of Covid, when work slowed down and budgets were tight, I found myself searching for recipes that didn’t need fancy ingredients or big spending. That’s when this simple chocolate cake became my kids’ absolute favorite.
Known as wacky cake or Depression cake, this recipe dates back to the 1930s, when families had to bake without eggs, milk, or butter due to shortages. What makes it so special is that it uses pantry staples, comes together in just minutes, and still produces a moist, rich, and deeply chocolatey cake.
Over time, I realized how versatile it was. Sometimes I baked it in a pan for a quick dessert, other times I poured the batter into muffin tins to make cupcakes for birthdays and school snacks.
And now, as Halloween rolls around, this same reliable recipe transforms into spooky monster muffins – a playful treat decorated with vibrant icings, edible sugar eyes, and creepy color combinations. It’s proof that simple recipes can carry us through hard times and still bring joy and creativity into the kitchen.
How I Make These Muffins
Whenever I make these muffins, I start by preheating the oven and getting my muffin tin ready with paper liners – in this case, I’m using Halloween-themed liners. Then I mix all the dry ingredients in a big bowl: the flour, sugar, cocoa, baking soda, and a pinch of salt.
I usually make little wells in the dry mixture for the wet ingredients, pouring in the oil, the vinegar, and the vanilla separately before stirring everything together.
The batter ends up quite dry, which always surprises me at first, but that’s exactly how it should be. I gently stir in the warm water to make sure everything blends smoothly, careful not to overmix. And here’s when the magic happens. It becomes super thin and wet, perfect to pour into the muffin cups, that’s why I always prepare the butter in a plastic pitcher.
So, now it’s time to scoop pour the batter into the muffin cups – I like to fill them about two-thirds of the way, leaving room for them to rise beautifully.
While they bake, the kitchen fills with an amazing chocolate aroma!
I let them cool completely before even thinking about decorating – otherwise, the icing will just melt into a sad puddle. Once cooled, they’re ready for their transformation into Halloween monsters.
I whip up some royal icing with an egg white and icing sugar (and some lemon juice drops), tint it in bright orange, green, and violet, and let my imagination run wild.
$ ~ Saving tip: You only need to buy red, blue, and yellow coloring -like I do- to obtain different colors.
>> Yellow + red = orange
>> Red + blue = purple
>> Yellow + blue = green
Sugar eyes go on while the icing is still soft, and suddenly plain muffins become mischievous little creatures. The best part? No monster needs to look perfect – the wobbly shapes and funny faces are what make them charming, spooky, and uniquely ours.
Why I Chose Crazy Monsters
When I was about 18, I actually started a cake decorating course. Life had other plans, and I never managed to finish it. Back then, I was quite good at piping and decorating, but now – more than 25 years later – I can admit it’s not as easy as it used to be. That’s where these creepy monster muffins come to the rescue.
Halloween is one of the most forgiving holidays when it comes to decorating. Monsters don’t need to look “perfect” – in fact, the messier and sillier they are, the better! Once you add those white sugar eyes, everything comes alive.
And really, who has ever decided what a monster is supposed to look like anyway? With Halloween, every strange shape, wobble, or swirl simply becomes part of the fun.
Chocolate Cake (Wacky Cake)
Ingredients
- 180 grams all-purpose flour
- 200 grams granulated sugar I use brown for richer taste
- 1.4 cup unsweetened cocoa powder
- 1 tsp baking soda
- ½ tsp salt
- 6 tsp vegetable oil (3 oz)
- 1 tbsp white vinegar
- 1 tsp vanilla extract
- 1 cup warm water
Instructions
- Preheat your oven to 180°C (350°F). Line a muffin tin with paper liners.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
- Make three little wells in the dry mixture: one for oil, one for vinegar, and one for vanilla. Pour each liquid into its own well.
- Add ¾ cup of the warm water and stir gently until combined.
- Add the remaining ¼ cup of water and mix until smooth. The batter will be thin enough to pour into the muffin tins. Don’t worry, that’s perfect.

Tips for Perfect Halloween Muffins

- Flavor twist: Add a teaspoon of instant coffee to enhance the chocolate flavor.
- Texture boost: Sprinkle mini chocolate chips on top before baking for extra gooeyness.

Halloween Icing (Royal Icing) Recipe
Royal Icing sets firm, making it perfect for monster-style decorations.
Ingredients:

- Spoon or pipe onto the cooled muffins. While still wet, stick on edible sugar eyes to create monster faces.
More Fun Decorating Ideas
- Monster Faces
Cover muffins with one color of icing, and add sugar eyes. You can even pipe a scary mouth with black decorating gel.

- Spider Webs
Frost with white or violet icing and draw thin white circles on top, then drag a toothpick from the center outward to make webs.
