By doing this, DMA stores the values not into TIM16_CCR1 but into memory where the DestAddress variable is located.

You want

DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t) &(TIM16->CCR1);

If you are in doubts, always start by reading out and checking the registers, here TIM and DMA registers.
