The 'cake theft' incident at Trump's inauguration.

American pastry master Duff Goldman was shocked to discover that the cake served at Donald Trump's inauguration was identical to a design he had created for Barack Obama's ceremony in 2013.

The 42-year-old renowned American chef has decided to launch a "community impeachment" on Twitter with his followers, according to Vanity Fair magazine on January 21.

"The cake on the left was invented by me for President Obama's inauguration four years ago. The one on the right is for Mr. Trump's inauguration. I didn't create it," Goldman said in the accompanying photo.

Goldman's creation consists of nine tiers, each with a different flavor, and is decorated with stars, stripes like the American flag, and the seals of the military and the president.

Buttercream Bakeshop, the bakery that makes cakes for Mr. Trump, admitted to receiving an order from the White House requesting that the cake be made exactly like the one Mr. Obama made previously.

"While we often enjoy creating new cake designs, we're happy to recreate old ones if asked, like this masterpiece," explained Tiffany MacIsaac, owner of Buttercream Bakeshop, on Instagram.

This means Buttercream Bakeshop denies the "copycat" accusation, stating that they were simply fulfilling orders, and adding that all profits are donated to a charity.

The Washington Post quoted MacIsaac as saying that the shop received the order several weeks ago, meaning almost at the last minute, and the customer insisted on having the cake look exactly like Obama's.

How can we know when the customer is always right!
