Preheat the oven to 350°F (175°C) and prepare a baking pan with parchment paper.
02 -
Combine lukewarm milk, lukewarm water, instant yeast, and 3 tablespoons granulated sugar in a large mixing bowl. Let sit for 5 minutes until foamy.
03 -
Add all-purpose flour and sea salt to the bowl. Mix until a soft dough forms, then knead on a lightly floured surface for 8-10 minutes until smooth and elastic.
04 -
Transfer the dough to a lightly oiled bowl, cover, and let rise in a warm spot for 1 hour or until doubled in size.
05 -
In a medium bowl, combine frozen raspberries, 1/3 cup granulated sugar, cornstarch, and fresh orange zest. Mix gently to coat berries evenly.
06 -
Roll out the dough into a large rectangle. Evenly spread the chocolate hazelnut spread over the surface. Distribute the raspberry mixture on top.
07 -
Roll each long side of the rectangle toward the center, meeting in the middle. Slice into 12 equal pieces using a sharp knife. Pinch the bottom of each piece to create a heart shape and arrange them, cut side up, in the prepared pan.
08 -
Cover the rolls loosely and let them rise for 30 minutes, or until noticeably puffy.
09 -
Bake in the preheated oven for 30 to 45 minutes, or until the rolls are golden brown and cooked through.

Allow rolls to cool slightly in the pan before transferring to a wire rack. Serve warm.
