The block reward is collected as one or multiple outputs in the coinbase transaction. These funds are subject to a 100 block maturation period.
The block reward is composed of two parts: The block subsidy, which is 12.5 BTC currently, and the collective transaction fees from all transactions in the block. Since the transaction fees are about one and two bitcoins in the blocks that you cite, block rewards amount to 13.5 and 14.5 BTC respectively.
Unfortunately, "block reward" is used inconsistently. Some use it for the "block subsidy" while others use it for the total coinbase output.
