Adding fresh fruit to cakes can be a tricky endeavor; you'll never really know how your cake is going to turn out until you cut it open. If you are using strawberries, it's essential to toss them in a bit of flour before adding them to the loaf batter. Doing this will help to prevent the berries from sinking to the bottom while baking. The flour will act as a protective barrier, providing your strawberries with enough buoyancy to remain suspended within the cake. Plus, the flour will also help to keep the berries from releasing too much liquid, which could otherwise result in a soggy cake. So, if you're looking to enjoy a moist and flavorful cake, be sure to toss your diced strawberries in flour before adding them to the batter.
