In a large mixing bowl, combine the softened butter and granulated sugar. Using an electric mixer, beat the mixture on medium speed until it becomes light and fluffy, about 3-4 minutes.
Mix in the vanilla extract and orange zest, ensuring that the ingredients are well blended and the mixture is fragrant.
Gradually sift in the all-purpose flour and salt, mixing on low speed. Continue to mix until a soft and cohesive dough forms.
Gently stir in the fresh orange juice until fully incorporated into the dough. The dough should be moist and slightly sticky.
Divide the dough in half and shape each portion into a log, roughly 1.5 inches in diameter. Wrap each log in parchment paper tightly and refrigerate for at least 1 hour, or until the dough is firm.
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cookie removal.
Once the dough is firm, remove the logs from the refrigerator. Using a sharp knife, slice the logs into cookies about 1/4 inch thick. Place the cookies onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading.
Bake in the preheated oven for 12-15 minutes, or until the edges are lightly golden. Once baked, remove the cookies from the oven and let them cool completely on a wire rack.
While the cookies cool, place the dark chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring in between, until the mixture is smooth and fully melted.
Once the cookies are cool, dip the edge of each cookie into the melted chocolate, allowing any excess chocolate to drip back into the bowl. Place the dipped cookies on a wire rack or a sheet of parchment paper to set.
After the chocolate has hardened, your delicious chocolate dipped orange shortbread cookies are ready to be savored!
Notes
For a stunning presentation, arrange the cookies on a decorative platter and garnish with fresh orange zest.
