Question about oil portion

One of my friends and I are planning on making a batch of some cupcakes next week. We plan on making it into oil rather than butter. However, the recipe calls for 1/2 cup of oil, and we are using 1 cup since we're using a half ounce. One idea I had was to just make two batches, but that seems like it might be less potent, and we want them reallllllly potent.

What can I do about these portions?

Make two batches and eat two cupcakes. I put extra oil in a batch of brownies once for potency and they came out too gooey. I was okay with it, but there was a visible difference from the regular proportions. Either way you'll probably have a good time though haha
