Cinnamon Pinwheels

Material :
400 g flour
1/2 tsp baking powder
1/4 tsp salt
100 g cinnamon red hot candies
300 g butter, softened
300 g sugar
1 egg
1/2 tsp vanilla extract
Red paste food coloring

How to Make :

1. On waxed paper, combine flour, baking powder, and salt
2. In mini food processor with knife blade attached (or in coffee grinder), pulse cinnamon candies until finely ground; set aside
3. In large bowl, with mixer at medium speed, beat butter and sugar until creamy. Reduce speed to low; beat in egg and vanilla. Gradually beat in flour mixture just until blended, occasionally scraping bowl with rubber spatula. Transfer half of dough to small bowl; with hand, knead in candies, then enough red food coloring to tint a pretty red
4. Between two 20-inch sheets of waxed paper, roll cinnamon dough into 15" by 10" rectangle. (If paper wrinkles during rolling, peel it off, then replace it to remove wrinkles.) Repeat with plain dough. Refrigerate dough rectangles 10 minutes or until chilled but still pliable
5. Remove top sheet of waxed paper from each rectangle. Place plain rectangle (still on waxed paper) on work surface with a long side facing you. Invert cinnamon rectangle on top of plain rectangle, so that edges line up evenly; remove top sheet of waxed paper. Starting from a long side, tightly roll rectangles together jelly-roll fashion, lifting bottom sheet of waxed paper as you roll. Wrap log in plastic wrap and freeze at least 1 hour or overnight, or until dough is firm enough to slice
6. Preheat oven to 325 degrees F. Grease large cookie sheet. Remove log from freezer. With sharp knife, cut log crosswise into 1/4-inch-thick slices. Place slices, 1 inch apart, on cookie sheet
