Steph of The Cupcake Project created a recipe called How to Make Cupcakes in Egg Shells.
But, if you decorate the eggs before serving, you have Easter Egg Surprise: an egg with cake inside.
It’s fun and memorable: Most people won’t have seen anything like it.
Here’s the recipe.
We took it one step further, using white eggs and decorating them.
This protects everyone from any bacteria on the egg, and protects the eggshells from any oils on hands that may prevent the dye from adhering.
HOW TO DECORATE CAKE EGGS AFTER THEY’RE COOKED
We used a wide paintbrush and took the advice of Incredible Egg to use water warmer than the eggs.
They also caution that hands should be washed in hot, soapy water before and after handling eggs—even if they’ve already been cooked or decorated.
Because a hole has been punched into the top of the shells to insert the cake batter (photo #1), you can’t fully dip cooked cake eggs in dye (well…maybe if you use dark chocolate cake, a bit of color won’t show).
Instead, you can try one of these three techniques.
Option 1: Try this if you have an exceedingly nimble grip, and can hold the eggs at the top while dipping them into the dye. We filled a juice glass with dye (diluted in water) that would not reach the top of the egg when the egg was added to the glass. The narrow glass held the egg upright. We could lift the egg out using doctors’ gloves and a spatula, but it wasn’t easy.
Option 2: We next moved to the hand-painted approach. Using wide hobby paintbrushes, we placed food coloring in ramekins, placed the egg upright on a nonslip mat and held it with one hand, as we painted swaths of color with the other.
Option 3: We didn’t try this one for lack of time, but we think it will work and could be the easiest. Dye the eggshells before adding the cake batter, and bake the cake in the colored shells. The cake eggs bake at 350°F for 23 minutes, so they should retain their colors.
You can practice the first two techniques with the raw eggs in your fridge (and return them for subsequent cooking).
Or, you can color whole eggs and then bake them in the oven to get hard boiled eggs.
The hard boiled eggs look and taste the same.
THE HISTORY OF EASTER EGGS
The tradition of painting hard-boiled eggs during springtime pre-dates Christianity. Fertility and rebirth are fundamental to life—not just for people but for the crops and animals that sustain them.
The most ancient known decorated eggs are 60,000 years old: engraved ostrich eggs found in Africa. Decorated eggs have also been found from prehistoric Egypt and the early cultures of Mesopotamia and Crete [source].
