These Raspberry Jam Pinwheel Cookies are a super simple but utterly delicious cookie recipe perfect for the holidays, teatime, or anytime you're craving a bite of deliciousness.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of a stand mixer fitter with the paddle attachment, or with a electric miser, cream the butter and sugar together until light and fluffy; about 3 minutes. Beat in the egg and vanilla until fully combined.
Add the dry ingredients and mix on low speed until just combined. Use a spatula to gently incorporate any remaining dry ingredients. If the dough feels too wet, add 1 to 2 tablespoons more flour.
Divide the dough in half. On a lightly floured surface or sheet of parchment paper, roll the dough into a rectangular shape; about 9 x 7-inches and ¼-inch thick. Trim the edges into a nice and even shape.
Spread the raspberry jam over the surface, leaving ¼ to ½-inch border around the dough.
Working slowly, roll the dough firmly and evenly at the long side (9-inch). If it begins to crack, press it back together and keep rolling into a log. Lightly wrap in plastic wrap and refrigerate until chilled; about 2 hours. Continue with the 2nd portion of dough.
Preheat the oven to 350°F and line a baking sheet with parchment paper.
Remove the dough from the refrigerator and cut it into ½-inch rounds. Place on the prepared baking sheet about 2 inches apart. Bake for 10 to 12 minutes. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
If you want to drizzle icing over the cookies, whisk together powdered sugar, milk, and vanilla until smooth and pourable.
