How-to
How to use a cake tester: where to insert it, when to start checking, how to read the result and how to care for the tool afterward.
The middle of a cake is the last part to set, and that is the only spot a cake tester needs to reach. Get the timing, the angle and the reading right, and the guesswork about whether the cake can leave the oven disappears.

The edges of a cake bake first and look done long before the middle does. The center is the thickest part and sets last, so a check there tells the truth about the whole cake.
For cupcakes and muffins, test the center of one of them instead of the whole tray.
The routine is short, and the timing matters more than the motion.
The wire gives one of three answers. The same read works with the toothpick alternative for baking, though a short pick may not reach the center of a deep pan.
| On the tester | Meaning | Next move |
|---|---|---|
| Clean or dry crumbs | Cake is done | Take it out |
| A few moist crumbs | Likely done | Optionally bake a little longer |
| Wet batter | Not set yet | Back in, check again soon |
The same check carries over to most baked goods that set from the middle out. Recipes that aim for a soft center, such as fudgy brownies, call for reading the crumbs rather than waiting for a perfectly clean wire.
After each bake, wash and dry the tester, then store it somewhere dry. Several models are listed as dishwasher safe, but the maker's instructions decide, so follow them for the specific tool. Look it over now and then, since a bent wire or rust means it is time to replace it. See our recommendations on which cake tester to buy for lengths and grip styles.
