This can happen for a variety of reasons but here's a few things to check: Don't overbake your pound cake. Check your pound cake a few minutes ahead of time by inserting a toothpick. It should come out clean or with just a few crumbs. Double check measurements. If ratios are off, this an effect moistness. Do not overmix pound cake batter. Mix just until combined. Get an oven thermometer. If your oven temp isn't calibrated correctly then it can cause baking times to be off.
