To prepare sunny apricot marbles candies recipe, first you need to gather your ingredients. You'll need: 1 pound (240 g) of ripe, unsalted, unpeeled, sliced, fresh, or dried, oranges; 1 cup (250 ml) granulated sugar; and 1 teaspoon (2.5 tsp) vanilla extract. Preheat the oven to 375 ?F (191 oC) and prepare your baking sheet. Line the bottom and sides of the pan with foil or parchment paper. Place the orange slices in the center of each foil-lined pan. Bake for 12 to 15 minutes or until the slices are lightly browned. Remove the foil and paper and let cool for 5 minutes. Cut each orange slice in half lengthwise, then cut each half into 12 inch (1.3 cm) slices. Set each slice aside. Melt the white chocolate chips over low heat until they are melted. Add the sugar and vanilla and stir to combine. Pour the chocolate mixture into the lined pan and bake for 15 to 20 minutes, stirring often. Allow the mixture to cool completely before cutting into squares. Store in an airtight container for up to 3 months.
