Just contact me for your coffee cake orders though instead of calling the number at the end of the video. I am their rep in this area. Thanks!
Here is a little info about the history of their company.

My Grandma's of New England® started an industry in 1990 with their original Cinnamon Walnut Coffee Cake - and with good reason. These decadent, dinner-worthy cakes are made from the finest and freshest ingredients available. The moistness and flavor of the cake are unmatched. All cakes are handmade and certified Kosher under Orthodox supervision

 And there really was a Grandma! My Grandma's of New England ┬« started baking coffee cakes in a modest 250 square foot bakery in a remote section of Newton, Massachusetts. Baking her famous Cinnamon Walnut coffee cake in her kitchen, Grandma's business grew steadily by word of mouth. Soon, customers were driving from locations as far away as one hour to buy one of her cakes that were still warm from the oven. Completely selling out was a daily occurrence. Around major holidays, word quickly spread that if you wanted a cake for your family to enjoy, you had to place your order at least one week in advance.

After moving to Dedham, Massachusetts in 1994, we expanded our flavor selection to include the Granny Smith Apple, Golden Raspberry and Cappuccino flavored coffee cakes.

Demand for our cakes was at an all time high in 1996, and in 1997, we relocated to our current facility at 1636 Hyde Park Avenue, in the Hyde Park section of Boston. Business remains solid and demand for our quality product has never been higher.

We launched our first My Grandma's Website in early 1998.

Today our line includes the New England Blueberry, Ted Williams Chocolate, Banana Walnut, Cape Cod Cranberry, Chocolate Chip, Red, White and Blue Patriot Cake, Pumpkin Spice and Lemon Poppy flavors.  All cakes may also be special-ordered without walnuts.

Our cake is packed in a plastic freezer bag that preserves freshness whether fresh or frozen. Shelf life in the bag is 14 days when unrefrigerated and up to 12 months if frozen. Cakes are shipped via UPS to arrive at their destination within 3 business days of shipment.
