Switzerland has many culinary delights to offer... Unfortunately cinnamon bread as we on t'other side o' the pond know it is not one of them.
But fear not, a little creativity solves the problem. Or craving in this case.
Get up early and head out to Wadenswil on the left side of the lake. Just at the Bahnhof you will find Cafe Brandli.

There you will find the closest aproximation I have yet to discover, their Zimtbrotli. This is not a loaf of bread but rather a roll, studded with heavenly cinnamon bits.
Get there by 8 AM as the Zimtbrotli go fast. Or call and reserve a few.
Zimtbrotli is not to be confused with a Zimtschnecke pastry, by the way. Horse of an entirely different color.
Back home, slice the roll lengthwise, in three parts. Dunk in your favorite French Toast mixture (I am partial to adding the juice and peel of an orange), and voila, a taste of home.
Or, since you've already come out this far, just pack those Zimtbrotli in your Rucksack and continue on the S13 to explore the delights of hiking in the Ausserschwyz and Einsiedeln regions. The Zimtbrotli will sustain you for a good few hours' hike.
Or start baking. Which is easier, but perhaps not as much fun.
Forgive the lack of umlauts and accents, using the iPad and am too lazy to hunt for them.
