Get ready for Halloween with this fun Eyeball Fault Line Cake, made from vegan green velvet cake layers and finished with green vanilla and black chocolate frosting. A hidden layer of candy eyeballs peeking through makes it extra spooky and festive.
Happy Thursday! I’ve been having so much fun with this #SpookyOctober series, and today’s creation is one of my favorites: the Eyeball Fault Line Cake. Inside, it’s a vegan green velvet cake, layered and frosted with bright green vanilla frosting and deep black chocolate frosting. The focal point — and the best part — is the row of candy eyeballs tucked into a fault-line-style gap along the side. It’s playful, dramatic, and perfect for a Halloween party.
This month my goal is to share at least one spooky treat each week, and this cake definitely fits the bill. It’s not my everyday decorating style, but Halloween is the perfect time to experiment with bold colors and silly details. I filmed the decorating process so you can see how the design comes together step by step — spoiler: placing the eyeballs is the most time-consuming part, but also the most satisfying!
Equipment you’ll need
This cake looks fancy but only requires basic cake-decorating tools:
- 6″ cake pans – I usually bake 6″ layers. Using two or three pans speeds things up and gives more even results.
- Cake decorating turntable – helpful for smoothing sides and working efficiently.
- Cake scraper – a straight metal scraper makes it easier to get tidy sides.
- Open star decorating tip – great for piping small swirls or rosettes on top.
- Decorating bags – disposable bags work fine; a large reusable bag is handy for covering sides and filling with frosting.
Special ingredients to consider
The recipe is mostly pantry-friendly, with a few items to make the look pop:
- Candy eyeballs — if you need a fully vegan cake, note that many store-bought eyeballs contain confectioner’s glaze. You can also make vegan googly eyes from scratch if you prefer.
- Green and black food coloring — used for the cake batter, green frosting, and to darken the chocolate frosting.
- Dark cocoa powder — using dark cocoa helps achieve a true black with less food coloring.
If you’re looking for a fun, show-stopping Halloween baking project, try this Eyeball Fault Line Cake. The contrast of bright green and deep black is eye-catching, and the peekaboo row of eyeballs adds playful creepiness. Below is the full recipe and instructions so you can recreate it at home.

Eyeball Fault Line Cake (Vegan Green Velvet)
Ingredients
- For the cake
- 2 tbsp ground flaxseed + 6 tbsp water
- 1 cup granulated sugar
- 1 2/3 cup + 1 tbsp all-purpose flour
- 1 tbsp cocoa powder
- 1 1/2 tsp baking powder
- 1 tsp baking soda
- 1/2 tsp salt
- 1/4 cup vegan butter, room temperature
- 1/3 cup nondairy yogurt
- 1/4 cup vegetable oil
- 1 tbsp vanilla extract
- 2/3 cup nondairy milk
- 1 cup vegan chocolate chips
- 1–2 tbsp green food coloring, for desired color
- For the frosting
- 1 cup shortening
- 1 cup vegan butter
- 4 cups powdered sugar
- 1 tbsp vanilla bean paste or vanilla extract
- 1–2 tbsp nondairy milk, as needed
- Pinch of salt
- Black and green food coloring
- Candy eyeballs
Instructions
- Preheat oven to 350°F and grease three 6″ round cake pans.
- Whisk the ground flaxseed with water in a small bowl and set aside to thicken.
- In a stand mixer bowl, combine flour, cocoa powder, baking powder, baking soda, salt, and sugar.
- Add vegan butter and beat on low until the mixture resembles coarse crumbs.
- In a separate bowl, whisk together oil, flax mixture, nondairy yogurt, and vanilla. Add to dry ingredients and mix until combined.
- Pour in nondairy milk and beat on medium-low until smooth. Add green food coloring to reach the desired shade.
- Divide batter evenly among the three pans and bake 30–35 minutes, until a toothpick comes out clean. Cool completely.
- Make the frosting: beat shortening, vegan butter, and vanilla until smooth. Add powdered sugar, 1 cup at a time, until thick. Add salt and 1–2 tbsp nondairy milk if needed for consistency.
- Separate about half the frosting into another bowl. Add 1 tbsp cocoa powder and black food coloring to that portion until you reach a rich black. Thin with a little nondairy milk if necessary.
- Leave the remaining frosting green by adding green food coloring until you reach your preferred color.
- Trim cake tops if needed. Place one layer on your stand and spread green frosting between layers. Stack all layers.
- Apply a thin crumb coat of green frosting over the whole cake and smooth. Around the middle where you want the fault line, apply a thicker strip of green frosting and press candy eyeballs into that strip to create the peekaboo effect.
- Chill the cake 15–20 minutes so the green frosting sets.
- Pipe or spoon black frosting around the cake, avoiding the eyeball strip. Smooth gently with a bench scraper, leaving slightly uneven edges at the fault line so some green shows through.
- For a two-tone topper, place black and green frosting side-by-side on plastic wrap, roll into a log, twist the ends, and transfer a cut end into a piping bag with your chosen tip. Pipe swirls on top, finishing with sprinkles if desired.
- Serve immediately or refrigerate until ready. Note: candy eyeballs may show condensation if refrigerated, so handle accordingly.
