Help!?
What can we use if we can't find the boxed cake mix or baking paper?
If you don't have the boxed cake mix, mix 1¼ cups plain flour, 1 cup sugar, 1/3 cup cocoa, 1 tsp baking powder and a pinch of salt to replace it, and if you don't have baking paper, grease the cake tin well with butter or oil and press a circle of foil into the bottom before pouring the batter.
My cake sank in the middle or the skewer comes out wet — what should I check?
If the cake sinks or the skewer/toothpick doesn't come out clean, make sure you added the eggs, milk and oil exactly as the box instructs, whisked the batter until it looked smooth and even, and ask an adult to bake it the full time on the box plus 5–10 minutes if needed before testing again.
How can I adapt the activity for different ages?
For younger children, focus on washing hands, measuring the boxed mix into the mixing bowl, and helping whisk and smooth the batter while an adult handles preheating and oven steps, and for older kids let them follow the whole process including cooling on the rack and spreading the chocolate frosting themselves with adult supervision for the oven.
How can we personalize or extend the Frosted Chocolate Sponge Challenge?
To extend or personalize the cake, stir chocolate chips or a spoonful of jam into the batter before pouring into the prepared tin, split the cooled cake to add a filling, or decorate the spread chocolate frosting with themed sprinkles and a photo setup to share on DIY.org.

Facts about baking for kids
🍫 Chocolate for frosting comes from cacao beans that grow inside pods on tropical trees — each pod can hold dozens of beans.
🔥 Preheating the oven is key for even rise — most cake recipes bake around 325–375°F (160–190°C).
📏 Scooping flour directly with a cup can add about 20% more flour than spooning and leveling, which can make cakes denser.
🎂 Sponge cakes get their fluffy texture mostly from whipped eggs and air, not from lots of chemical leaveners.
🧁 With just a piping bag and a few tips you can create dozens of frosting designs like rosettes, stars, and shells.
