🔪 How to make mini egg tray bake cake
Prep: Preheat the oven to 180°C (160°F/350°F/Gas 4) and line a 20 x 30cm traybake tin with baking paper.
One: Cream together the softened butter and sugars until light and fluffy. You can use a wooden spoon or an electric mixer.
Two: Beat in the eggs one at a time and mix in the vanilla extract.
Three: Fold in the flour and crushed mini eggs. Make sure the mini eggs are crushed into very small pieces, otherwise they will sink to the bottom of the cake.
Four: Spoon the cake batter into the prepared tin and bake for 30-35 minutes until golden brown. Set aside to cool.

Five: To make the buttercream frosting, mix together the icing sugar, softened butter, vanilla extract, and milk with an electric whisk until smooth and creamy. If the mixture is still a bit stiff, add a touch more milk.
Six: Remove the cooled cake from the tin then spread the top of the cake with the smooth vanilla buttercream. I use a palette knife.
Seven: Sprinkle the top with the crushed mini eggs before cutting it into slices.

Top Tips
- Make sure all your ingredients (especially the butter and eggs) are at room temperature before you start the recipe.
- Test the mini egg sponge to see if it is done with a skewer or tooth pick. If there is wet batter sticking to the skewer it needs a bit more time in the oven. When it's ready it should come out clean with a few crumbs attached.
- Crush the mini eggs for the cake batter really finely to prevent them from sinking to the bottom of the cake.
🍴 Serving suggestions
Serve the mini egg cake at Easter parties with Easter rocky road, creme egg tiffin, and simnel cake muffins.
It's also great as an Easter dessert with a scoop of mini egg ice cream.

Storage
Store - The iced cake can be stored in an airtight container or cake tin for up to 3 days.
Freeze - It's best to freeze the cake uniced. Wrap the mini egg sponge cake in clingfilm (plastic wrap) and foil and freeze for up to 3 months. Defrost at room temperature before icing it.

❓ Frequently asked questions
Yes, you can make this cake gluten-free by using a gluten-free self-raising flour in place of the regular self-raising flour.
Yes, you can use a different type of frosting if you prefer, such as cream cheese frosting or a white icing glaze instead of the vanilla buttercream frosting.
Troubleshooting Guide
Dry cake - Overbaked or oven too hot; check early and use an oven thermometer
Sunk middle - Opened oven too soon or underbaked; keep the door closed until set
Mini eggs sinking - Pieces too large; crush finely before adding
Dense sponge - Overmixed or ingredients too cold; mix gently and use room temp ingredients
Runny buttercream - Butter too soft or too much milk; add icing sugar or chill briefly
Stiff buttercream - Too much icing sugar; add milk a little at a time
Cake sticking to tin - Tin not lined or removed too hot; line well and cool before removing
Uneven bake - Oven hot spots or uneven batter; level batter and rotate tin if needed
