Grandma’s Oven Bakery & Cakes – Designing Confectionery Masterpieces

Wedding Cake and Cookies

In 2008 Anna Hiebert and her daughter Martha Zacharias embarked on a journey to fulfill a lifelong dream of opening a bakery. Although they had no formal training, Anna was a tremendously skilled baker with experience creating delicious homemade treats for her family. The decision to open Grandma’s Oven Bakery in Aylmer was a daunting one but the initial leap of faith paid off as eight years later the business is a huge success.  The bakery started by employing only family but over the course of time has grown to accommodate increased demand for its delicious sugary treats. 

For the past eight years Anna and Martha have worked alongside each other as business partners – Anna baking and supervising staff and Martha running the business and taking care of custom cake orders.

Martha has recently taken over as sole proprietor as Anna slowly works towards retirement. In the meantime she is still expertly whipping up traditional recipes from her Mennonite background that include pies, fresh breads, squares, and cookies of all types. Customer favourites include chocolate filled cream cookies, chocolate dipped marshmallow cookies, cornflake cookies, cake truffles, cheesecakes, and deliciously decadent cupcakes in a variety of enticing flavours. These flavours are continuously changing and include everything from strawberry swirl with cream cheese, chocolate peanut butter, and red velvet to lemon and chocolate with cookies and cream.  

Martha has always enjoyed baking but her artistic side longed for a creative outlet. She began by creating basic cakes for special occasions and weddings and has worked up to designing edible works of art that are nothing short of confectionary masterpieces. 

Word has spread about Martha’s artistry and not only are her cakes a hit in Aylmer, but across southwestern Ontario as well. She now makes cakes, cupcakes, cake pops, and cake truffles for approximately 200 weddings a year with a large portion of her business coming from the London area. Martha’s reputation has even reached the Muskoka area where she recently delivered a wedding cake to an extremely satisfied couple.
