Step 1: Prepare the Date Filling - Place the pitted dates in a food processor with the olive oil. Process until you achieve a smooth paste. Set aside.
Step 2: Mix the Dry Ingredients - In a large mixing bowl, combine the all-purpose flour, semolina, instant yeast, ground mahlep, and powdered sugar. Stir until evenly mixed.
Step 3: Combine Wet Ingredients - In a separate bowl, whisk together the melted clarified butter and milk. Gradually add this mixture to the dry ingredients, mixing until a soft dough forms.
Step 4: Shape the Cookies - Preheat your oven to 350°F (175°C). Take a small piece of dough and flatten it in your palm. Add a teaspoon of the date filling in the center, then fold the dough over the filling and shape it into a ball.
Step 5: Bake - Place the shaped cookies on a baking sheet lined with parchment paper. Bake for 20-25 minutes or until lightly golden. Allow them to cool slightly before dusting with powdered sugar.
Step 6: Serve and Enjoy - Your Mamoul are ready to be enjoyed! Serve them warm or at room temperature.
