2 bishops of the same color

I was winning a game and I decided I would try something unique instead of getting a rook or queen in the end game I would try 2 bishops of the same color to see if it would give a draw, surprisingly to me it still gave me the win, now how is it possible to use 2 dark bishops to win a game with a king?   I think chess.com needs to fix this

any thoughts on this?

It is not possible to mate with two bishops on the same colour because the king can just stay on the light squares and never get checked.

Chess.com thinks this is a win for you because it only checks your material. In fact, it thinks you cannot win with just a knight against a pawn, as I have seen a few posts of games that were drawn on timeout with insufficient material, where the opponent timed out but it was a draw because the opponent "didn't have enough material to force a mate".

No it doesn't.

"6.9 - Except where one of Articles 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.2.3 applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves."

This quotation is from the FIDE Laws of Chess regarding draws by insufficient material. Since your opponent had a pawn, and the possibility to checkmate your king, they didn't have what is considered to be insufficient material.

How is black winning when they have insufficient material?

So if my opponent didn't have the pawn then it would be a draw I guess lol

Chess.com sadly, but understandable, doesn't use Fide rules in the case of insufficient material. They need something that is more easily evaluated than whether or not to be able to mate.
