As business magnate Warren Buffett turned 90, his close friend and billionaire philanthropist Bill Gates baked a special cake for him.

In a video that has gone viral on social media, Bill Gates can be seen baking a special Oreo cake bearing Buffett’s face.

“Warren has the mental sharpness of a 30-year-old, the mischievous laugh of a 10-year-old, and the diet of a 6-year-old,” Gates wrote in his blog.

“Here’s a short birthday video in honour of his dietary preferences,” he added, sharing the video.

In the clip, one can see Gates entering a kitchen ready to bake a cake.

The remaining video shows a close-up of the entire baking process followed by the big reveal – the finished cake with Buffett’s face on it.

At the end of the video, Gates cuts a piece of the cake and puts it on a plate. The message “Happy 90th Birthday Warren” can be seen written next to it.
