Narrative:

Cessna 414 called; requested IFR departure clearance from I6's (mt sterling; il) to ZZZ. I issued the clearance as filed and assigned 15000 ft and the correct squawk at XA00Z. At about XB00Z; peoria approach called and said pointout approved on specific code climbing. I responded that 'I don't know who that was but I thought ZAU was working the aircraft VFR.' at XA00Z brl lo sector in ZAU called and asked about aircraft X. They had a code near pia at 15000 ft and thought I forgot to make a handoff. I said I didn't clear him and I thought they had done it. I asked for a radio check from aircraft X and he said loud and clear. I asked if he was given a clearance and he said affirmative but he was not radar idented. I called aircraft X radar contact and made the departure entry into the computer. I then handed off aircraft X and changed his frequency to ZAU. I forgot that I gave the clearance and didn't enter the departure message in the NAS computer. Traffic was light and there were no mitigating circumstances.
