Victoria sponges, flapjacks and cupcakes were among the sweet delicacies baked for charity.
About 25 employees of York Ward and Rowlatt Vauxhall dealership in Wellingborough gave up their time and ingredients to produce the cakes for a sale in aid of Help For Heroes.
Judy Povey, spokesman for the firm, said £365 was raised for the cause.
She said: “Visitors came along steadily throughout the day.
“We would like to thank our customers who came and we were delighted with the £365 raised.”
