Enhanced Goodberries is a component of SimDing0's Tweak Pack.
Here is a list of all the components (the download link is at the bottom of the list), but the change to Goodberries is...
"
/----------------------------------
| Component 1: Enhanced Goodberries
\----------------------------------
The Goodberries spell was effectively useless in the original game. The ability to consume an item in combat and heal 1 hit point is pointless when you're level 30. This component causes the amount of hit points healed by Goodberries to increase with levels.
The progression is as follows:
Level Hit Points Healed
3 (or less)...1
6 ...............3
9 ...............5
12..............7
15..............9
18.............11
21.............13
I do not consider this too overpowered for a level 2 spell, but it may retain some purpose, while being less useful in most circumstances than healing spells or potions. "
