Brownie baked inside an eggshell

Brownies baked inside an eggshell. I know what you are thinking… But why? Well, just because it is fun to watch people reaction when face to what they think it is a hard boiled egg, but then a brownie comes instead… You can prepare them for Easter, or April fools’ day. You must admit, it is an eggcellent idea!

{Egg shell brownie}

Summary: Brownies cooked inside an egg shell, after the indications on this post


  • 12-16 eggs for the shell (or an 8 inch pan if you want to bake a classic brownie)
  • 7 oz bittersweet chocolate, chopped (200 g)
  • 1 stick butter, room temperature (125 g)
  • 3 large eggs
  • 1 cup granulated sugar
  • 1 pinch of salt
  • 1 cup all-purpose flour
  • 3 Tbls unsweetened cocoa powder


  1. To prepare the egg shells, carefully poke a small hole at the bottom of each egg, using a corkscrew bottle opener.
  2. Once you have poked a tiny hole, peel back the edges of the hole to expand it a bit. The holes need to be large enough to fit the tip of a piping bag inside.
  3. Turn the egg upside-down and dump out the contents, which you can store for other preparations I used a wooden skewer to help get all of the egg out of the shell.
  4. Rinse the insides of the eggs out thoroughly over the sink. Then, immerse them in saltwater for thirty minutes (100 g salt for every 1 liter water). Eggs need to be filled with the saltwater in order to sink.
  5. Rinse the egg shells in cold water and lay
    the eggs hole side down on a paper towel to dry.
  6. Drizzle about 1 teaspoon of sunflower oil in each egg and turn/flip it in your hand until the inside is completely covered. Get rid of any excessive oil. The easiest way to pour de oil inside the egg shell is to use a small funnel.
  7. Prepare the brownie batter.
  8. Put the chocolate and butter in a medium heatproof bowl and set over a pan of simmering water, or melt in the microwave Melt the chocolate and butter, stirring occasionally until smooth. Remove from heat and set aside to cool.
  9. In another medium bowl whisk together the eggs and sugar at low-medium speed until combined.
  10. Whisk the warm chocolate mixture into the egg mixture.
  11. Stir in the flour, salt and cocoa powder with a wooden spoon until just combined.
  12. Place the prepared egg shells into a cupcake tin. Use aluminum foil to help them stand upright.
  13. Load the batter into a piping bag fitted with a round tip. Make sure that the tip can fit the egg hole. If it can’t, expand the hole a little bit at a time until it fits. Fill your eggs about 3/4 full with batter. This is the tricky part. If you underfill the eggs, you won’t have a complete cake egg inside when you crack them after baking. If you overfill the eggs, cake will overflow out of the egg during baking. It looks ugly right after baking, but just remove
  14. the excess cake and clean the shell with a damp towel. It is important to do this when the cake is still hot, when cold it is much harder to clean the shell.
  15. Bake the eggs at 350º F for 15-20 minutes. Let cool, crack, and eat!

    this excellent blog, “Brownie baked inside
    an eggshell”. Will you mind in case I actuallyimplement some of your own concepts?
    Thanks for your effort -Freda

    Hello Sandeea,

    I’m inspired a lot by your recipe brownie in egg :D

    In Taiwan, it’s popular to bake pudding in eggshell, but I haven’t seen cake in eggshell before ! I cited one of your picture and link to your website on my facebook page.
    If it’s not proper to cite your picture, please let me know thank you so much !

    My soulmate and I made these today…so much fun. We filled each large brown egg shell 3/4 and they all overflowed. Maybe only fill each 1/2 way??

    Overall, they were a curious treat and were enjoyed by all.

    Wow, doing this for easter!
    Can I still colour the eggs afterwards?
    Have you tried what happens when using hot colours?

    Have a good weekend!

  18. 13 April 2015, 2:52 pm - katie

    I tried it and you can even use hot colours if you don’t leave the eggs in te hot colour too long, it will still be fluid.
