Ingredients
- All purpose flour: ensures cake structure Look for unbleached for best flavor
- Baking powder: helps the cake rise evenly Use a fresh container
- Salt: balances flavors and boosts sweetness
- Salted butter: brings richness Its fat content also makes your cake tender
- Shortening: lightens the texture and helps the crumb stay soft
- Sugar: sweetens and caramelizes for just a hint of golden hue
- Peppermint extract: brightens the flavor Pick a pure extract rather than imitation
- Egg whites: provide lift and keep the cake subtle in flavor Use eggs at room temp
- Milk: moistens and blends everything together Whole milk adds the most richness
- Neon green food color: makes the eggs pop Gel color gives vibrant results
- Green buttercream frosting: adds a creamy gooey layer Storebought or homemade
- Green royal icing: creates that slime effect Gel paste colors work best
- Chocolate fondant: forms the tough outer shell Use a good quality brand for easier rolling
Instructions
- Make the Batter:
- Begin by heating your oven to three hundred fifty degrees Fahrenheit This step ensures even baking from the moment your pan enters the oven In a medium mixing bowl measure out the flour baking powder and salt Whisk together until there are no lumps The even distribution is key for a tender crumb In a separate large mixing bowl use a hand mixer or stand mixer to cream together your butter shortening and sugar Beat them for about three to four minutes on medium speed until light and fluffy This step introduces air for a lighter cake Add the egg whites to the creamed mixture one at a time Be sure to mix each in thoroughly before adding the next Scraping down the bowl between additions helps maintain a smooth batter Pour in the peppermint extract and blend It should smell cool and fresh at this point Alternate adding the dry mix and the milk into your wet ingredients Do this in three additions of dry and two of milk Always start and finish with dry ingredients to keep the mixture from curdling Mix on low just until everything comes together Line your cookie sheet with parchment and spray lightly with nonstick spray Spread the batter in an even layer to promote uniform baking Bake in the center of the oven for about eighteen minutes The surface should look matte and spring back when lightly touched Let cool completely before handling
- Prepare and Assemble the Eggs:
- Crumble the cooled cake into a large bowl and mix in a spoonful or two of green buttercream Working with gloved hands is easiest Scoop and roll into balls They should be about the size of classic truffles Roll out your chocolate fondant to about one eighth inch thick Use a template or a round cutter to create shells big enough to wrap each cake ball Encase each cake ball with the fondant and press the edges to seal For some eggs leave the tops slightly open to show the green interior Trim away any extra fondant
- Decoration and Finishing Touches:
- Pipe green royal icing around the tops of each egg letting it drip down like slime Create as much or as little ooze as you like If you want extra shine add a second coat after a few minutes Arrange your finished Alien Egg Cake Balls on a platter and admire your extra terrestrial handiwork

My favorite part has to be the chocolate fondant shell Watching little hands stretch the covering over each egg reminded me of my childhood afternoons with cousins and flour everywhere It is a memory that keeps me smiling every time I make these
Storage Tips
You can keep finished cake balls sealed in an airtight container in the refrigerator three to five days This keeps them moist and fresh If you plan ahead you can freeze the undecorated cake balls and wrap them well in plastic then finish decorating when you need them for a party
Ingredient Substitutions
If you do not have peppermint extract try a drop of vanilla for a more classic flavor Instead of chocolate fondant you can use any color fondant or even modeling chocolate The buttercream can be homemade or store bought as long as it is thick enough to bind the cake crumbs
