MOSFET driving MOSFET for reduced reduced Rds
This doesn't drive the output MOSFET with a higher gate voltage - it will only see about 2V as the first MOSFET is acting as a source follower - the 5V from the MCU will be reduced by the threshold.

To drive the output stage with a higher voltage will require a couple of stages. Something like the following schematic. Bec careful about exceeding the VGS of the output stage.

You don;t say if you are using PWM modulation, if you are you will need to ensure fast charge and discharge of the MOSFET gate capacitance - this circuit may not be adequate.
