It’s fat bonus time for employees of Hostess.

The Kansas City-based snack-cake maker says that starting next week, it will give employees free weekly multipacks of goodies, like Twinkies and Ding Dongs, plus samples of other sugary treats it makes — thanks to the recent tax overhaul.

And the free snacks are just the icing on the cake.

Last Friday, all 1,036 hourly employees were handed $500 in cash, and each is also getting an extra $750 this fiscal year to put toward his or her 401(k) account, a company rep told The Post.

Hostess Brands Chairman Daren Metropoulos said it was the least the company could do after benefiting from the Republican tax bill, which was enacted in December.

“The recent tax-reform changes have given us the opportunity to review our benefit and compensation structure,” he said in a statement. “The company’s management and board take great pleasure in sharing the company’s success with our employees.”

In addition to the iconic Twinkie, Hostess makes Ding Dongs, Ho Hos and Donettes, as well as muffins and coffee cakes.

The company said a representative from each of its bakeries will be in charge of choosing a “product of the week” and shipping multipacks of it to each employee.

The baked-goods conglomerate is the latest in a string of companies that have pledged to use part of the large corporate tax cut to both incentivize workers and keep them from jumping ship.

American Airlines, Starbucks, Disney, Home Depot, JPMorgan Chase and others have announced wage raises, one-time benefits or other bonuses for employees.
