Yes, the cake is definitely under baked. Even if a cake has a perfect golden brown edge and nice looking crust, but still sinks in the middle, you didn’t bake it for long enough. The cake should have a springy texture, not a gooey one. If you are unsure of whether the cake is baked through, try doing the touch tests. When poked, the centre of a perfectly baked cake springs back. If yours doesn’t, bake it till it does! You can also insert a wooden skewer or a toothpick in the centre of the cake. If it comes out clean, your cake is ready! Another off the list of most frequently asked baking questions.
