Introduction
I started baking custom cakes in 2016 when my daughter turned 1. I wanted to create something that would make a statement for her first birthday party and since I didn’t have the budget to invest in a professional baker, I decided to do it myself.
After making my daughter’s first two cakes, once my son was born I’ve made birthday cakes for both my kids every year since and the designs became more elaborate with each birthday. Eventually, I found myself getting custom cake orders from family members and friends for all sorts of events. At that point, since I enjoyed it so much, I decided it was time to start selling cakes professionally and at the end of 2024, Monumental Cakes was born!
My goal is to help you create memorable experiences and shared moments of joy with your friends and family. I love to help people elevate major milestones or turn everyday occasions into unforgettable memories. I do this by baking my cakes with passion, creativity, and the finest local ingredients available.
I know exactly how important those moments are and I feel privileged to be a part of them, which is why I guarantee the quality of every single one of my cakes. I’m committed to your vision and to providing my customers with a great experience from start to finish.
I don’t discriminate. I love living and working with families in Charlestown but I make custom cakes for everyone and any occasion. I’m happy to work with any budget or dietary restrictions you may have. So, start an order and let’s get to work on making your dream cake a reality!

I got an amazing Justin Bieber cake from here! The cake was absolutely delicious and Justin was super easy to work with. It turned out just how I wanted! My only critique would be that the writing on top of the cake was a little messy, but not a huge deal. Definitely recommend!

Justin is probably the most talented baker in Massachusetts, he baked this beautiful cake for a special occasion for me and it tasted absolutely delicious, the care, thought, and detail that was put into the effort of this cake I cannot begin to explain. Such a wonderful experience. Now he'll be my go to for cakes!

So so so glad I ordered from this bakery. I got a 3 tier 6 inch cake for my husbands 40th. Justin was extremely responsive and was able to accommodate my order that no other bakery would. The design of my cake was perfect. It was delicious. 10/10 would order from them again :)

Amazing! Justin did my sons first birthday cake. It was adorable, so well done and absolutely delicious. Even non-cake lovers loved it. He was easy to work with, super responsive and brought my idea to life. Would definitely recommend and will work with him again on future cakes.
