Preheat the Oven: Set your oven to 350°F (175°C) and line a baking dish (about 8x8 inches) with parchment paper.
Mix Wet Ingredients: In a bowl, stir together Greek yogurt, honey (or maple syrup), orange zest, vanilla extract, and a pinch of salt until smooth.
Combine Dry Ingredients: In another bowl, mix the rolled oats, dried cranberries, nuts, and cinnamon.
Bring It Together: Pour the wet mixture into the dry ingredients. Stir well until everything is nicely combined.
Press and Bake: Spread the mixture evenly in the prepared baking dish. Press it down firmly. Bake for about 20-25 minutes or until golden brown.
Cool and Cut: Let the bars cool completely in the dish. Once cool, lift out the parchment paper and cut into squares or rectangles. Enjoy
