Is Trump's inauguration cake a copycat of Obama's 2013 cake?

Uh oh.

Celebrity baker Duff Goldman tweeted Friday that President Trump’s inaugural cake is identical to the one he made for President Obama in 2013.

The only problem? He didn't make Trump's cake.

The Food Network star posted a photo of the cake he prepared for President Obama alongside the cake from President Trump’s inaugural ball Friday.

“The cake on the left is the one I made for President Obama's inauguration 4 years ago,” Goldman tweeted. “The one on the right is Trump's. I didn't make it.”

President Trump and Vice President Mike Pence cut the nine layer cake, which looks identical to Goldman's 2013 cake, at The Salute to Our Armed Services Inaugural Ball on Friday.

Tiffany MacIsaac, owner of Washington’s Buttercream Bakeshop, told The Washington Post she created Trump's much-talked about cake.

“They came to us a couple of weeks ago, which is pretty last minute, and said ‘We have a photo that we would like to replicate,'” MacIsaac told the Post. She said bakery associates told the caller to use the pictures as "inspiration," but they asked for an exact replica.

She told the Post that the cake was meant to be a prop.

“It’s just a Styrofoam cake. It’s not for eating,” she said. “I wasn’t expecting it to be seen on TV.”

MacIsaac told the Post she did not meant to upset Goldman.
