National Chocolate Cake Day is coming up on Monday, January 27, and Magnolia Bakery is making the day special with an offer for its DoorDash customers.

In honor of the food holiday, Magnolia Bakery is giving away a free slice of chocolate cake with chocolate buttercream with any purchase of $20 or more from the bakery chain through the food delivery platform.

This offer is valid for one day only in New York, Los Angeles and Chicago bakeries when ordering through DoorDash.

Also available through DoorDash is Magnolia Bakery’s new line of frozen-to-thaw Banana Puddings, an airy, whipped frozen dessert that’s made with real bananas, naturally flavored and does not melt when thawed from frozen in the refrigerator.

They’re priced at $9.99-$10.99 per 14-ounce cup and come in three flavors – Wafer Cookie Bits, Chocolatey Hazelnut Swirl and Red Velvet Cookie Bits.
