Adrian Peterson was like a living, breathing genie last night ... 'cause when his "n-word" DJ Whoo Kid asked for a red velvet cake, AP made it his personal mission to deliver the baked goods.

Whoo Kid made the plea for his favorite cake on TMZ just a few days ago ... saying he'd wave his $10,000 fee if a Super Bowl MVP asked him to DJ his party and provided his favorite dessert.

Whoo Kid said if anyone could make that happen, "I'll be your n-word for the night."

Clearly, Adrian got the message ... because he rounded up an RV cake with the message, "n-word we made it" ... and presented it to the DJ at W.i.P. nightclub in NYC last night.

Now, technically, Adrian isn't a Super Bowl MVP ... but he IS an NFL regular season MVP.
