Retro food is popular now, and people want old tastes. One dessert coming back is a classic school sponge cake with jam and custard.

Nate Anthony shared how to keep sponge cake moist without an oven on TikTok. He uses a different appliance.

The slow cooker helps keep the sponge moist and fluffy, not the oven. Nate said, "You can make a classic jam and coconut sponge in your slow cooker."

Baking in the slow cooker keeps the cake moist.

Nate said, "This reminds me of school. My mum made it, but she used a box mix."

To make it, mix butter and sugar, then add other ingredients. Pour the mix into the slow cooker and let it cook.

Put a tea towel over the slow cooker before closing the lid to keep the sponge moist.

You can use any flavor jam you like, or try lemon curd.
