I think the pecan butter tart from Annex Espresso Bar is from Circle and Squares. The butter tarts ($5) at Krave Espresso on St Clair W are from Circle and Squares. I understand Circle and Squares are telling all the coffee shops who stock their tarts, that their butter tarts are the best in Ontario or Canada. 
Hard sell from the barista. I told him maybe best in Toronto right now. Maid’s Cottage used to tell the coffee shops they supplied that they had the best butter tarts in Toronto.
They’re good tarts, but so are BaNoi, Andrea’s, Gerrard Street, Dough’s, etc. Of course, rural butter tarts in Grey County, and in Muskoka, and in Orangeville, and elsewhere in Ontario, are great, too.
I tried the pecan butter tart from Annex Espresso Bar yesterday. It’s fine. I like BaNoi and Maid’s Cottage butter tarts more.
Better pastry and filling at BaNoi. BaNoi’s tart is maybe a little closer to a salted caramel taste than Grandma’s butter tart would have been.
I don’t know where or when the clumsy thick-crusted quarter pound butter tart trend began. I like my butter tarts to be smaller with a delicate flakey crust.
I found the crust too heavy and thick in this pecan butter tart, which I believe is sourced from Circle and Squares.
The mocha square from Annex Espresso Bar was right up my alley.
