Prep Work: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or a silicone baking mat.

Combine Dry Ingredients: In a medium bowl, whisk together flour, baking powder, and salt. Set aside.

Cream Butter and Sugar: In a large bowl, use an electric mixer to cream together the softened butter and granulated sugar until light and fluffy.

Add Eggs and Vanilla: Beat in eggs, one at a time, followed by the vanilla extract. Ensure each egg is fully incorporated before adding the next.

Mix in Sour Cream: Add the sour cream and mix until well combined.

Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Avoid overmixing.

Form the Cookies: Roll the dough into balls or use a cookie scoop. Gently flatten each ball to form a thick disc. Place them on the prepared baking sheets, leaving enough space between each cookie.

Bake: Bake in the preheated oven for 10-12 minutes, or until the cookies are set but not browning. Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.

Make the Frosting: While cookies cool, beat together butter, powdered sugar, milk, and vanilla extract until smooth. Add a few drops of food coloring to reach the desired color.

Decorate: Once cookies are completely cool, spread the frosting on each cookie and add sprinkles.

Serve and Enjoy: Let the frosting set for a bit, then serve these beautiful, soft Lofthouse-style cookies to your loved ones
