Preheat oven to 375° Fahrenheit and grease a 9-inch glass pie pan (or a spring form pan) with butter and then toss in 1 Tbsp of sugar and tip pan to coat entirely.

In a large bowl, whisk together the sugar, eggs, half and half, orange zest, salt, and vanilla extract until fully combined. Add in the flour and mix well then set aside. Separately, pour the coarsely chopped cranberries and walnuts straight into the greased pie pan and then pour the clafoutis batter over the chopped mixture (the berries and nuts will start to float to the top).

Bake for 30 minutes or until set in the center then remove from oven and let cool completely before dusting with powdered sugar (optional) and serving for a colorful, classic, and simple dessert with a touch of fall!
