The number of slices in a pound cake can vary depending on the size of the cake slices and the specific recipe used. As a general guideline, a standard pound cake recipe typically yields around 12 to 16 slices from a 9x5 inch (23x13 cm) loaf pan or bundt pan.
However, the thickness of the slices and the overall size of the cake can affect the number of servings. If you cut thinner slices, you may get more servings, and if you cut thicker slices, you may get fewer servings. Additionally, if you're using a different pan size or altering the recipe, the number of slices may vary.
To get a more accurate estimate, you can divide the weight of the whole pound cake (after it's baked) by the weight of a single serving, accounting for the desired slice thickness. Keep in mind that these numbers are still approximate, as the actual number of slices can differ based on personal preferences and cutting technique.
