Brownies

The first time he saw the brownies, he threw them in the bomb disposal chute -- because what evil lair doesn't have a bomb disposal chute? -- and then summoned his head of Security and did the same with him.

The second time a mysterious plate of brownies appeared in his supposedly-impregnable inner sanctum, he had them analyzed -- chemically dismembered for poisons or mind-control drugs, scanned for radioactivity and nanobots, the plate fingerprinted and traced to point of sale -- and then, because they were dark chocolate and that seemed only appropriate, and also because they smelled really amazing, he surreptitiously ate the one remaining brownie that had survived the process.

When the third plate was sitting innocently on the corner of his expansive black-glass desk, he did a cursory test for the more likely toxins himself, then took the brownies with him to his favorite leather armchair and slowly, luxuriously worked his way through them; and when he was done, he decided not to close the gap he'd finally found in his security net, just yet.
