Happy Customers


I was recently at my friend’s wedding. She had the most beautiful cupcakes! I couldn’t get enough of them. I think I tried every flavor (all delicious). I had to know where they were from. Needless to say I will definitely be using Sweet Mixin’s for my own wedding. – Josie, Johnson Creek

Everything about Sweet Mixin’s cakes is amazing! The taste, the decorating…absolutely amazing! The flavor choices are wonderful. It would be difficult to choose a favorite, because each one I’ve tried has been just delicious! (Well, maybe the chocolate fudge – outstanding!) The decorating is incredible. Her flowers are gorgeous…they look like they come straight out of a magazine! And she can find a way to make or recreate just about anything. The cake for my husband’s retirement party (from the Fire Department) had flames, a hose squirting water, even a replica of his helmet! Absolutely amazing!! – Laura W.

I attended my niece’s birthday party and when it came time for the cake, it was a beautifully decorated unicorn and it was absolutely scrumptious! I’m already looking forward to the next party just so I can have another piece of delicious cake! Mary is not only a cake decorator, but her artistic abilities make her cakes look unique. I highly recommend Sweet Mixin’s for any occasion. – Terri
