I have a question about the recipe "Chocolate Mochi Snack Cake" from Sarah Jampel. Do I go by the cups or the ounces in this recipes? They don’t seem to match! Thank you.
Measurements may not be exact, as sometimes recipe writers round up in converting back and forth from Imperial to metric or vice versa.
If you want exact, get a chart or a scale and do them to your satisfaction.
If you have no tools or time, use the volume measurements.
There are more of them, so it was probably developed using volume. And many have made the recipe as written with great success.
If you are still unsure, find another chocolate mochi cake recipe, especially one from UK or Canada where both measuring systems operate and recipes are often written for both.
