Cream the butter and sugar together until light and fluffy, about 2 to 3 minutes.
Beat in the egg, egg yolk, sour cream, vanilla extract, and almond extract until smooth and fully combined.
In a separate bowl, whisk together the flour, cornstarch, baking powder, and salt.
Add the dry ingredients to the wet ingredients and mix just until combined.
Cover the dough and refrigerate for 30 minutes.
Preheat the oven to 350°F. Line two baking sheets with parchment paper.
Scoop the dough into 3-tablespoon portions and place them 3 inches apart on the prepared baking sheets.
Flatten each dough ball into a thick disk about 3 inches wide.
Bake for 10 to 12 minutes or until the cookies are puffed and set. The tops should remain pale.
Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Frosting
Beat the butter until smooth and creamy.
Add the powdered sugar, heavy cream, clear vanilla extract, almond extract, and salt.
Beat for 3 minutes until light and fluffy.
Assembly
Pour the rainbow nonpareils into a shallow bowl.
Spread a thick layer of frosting over each cooled cookie.
Turn the frosted cookie upside down and gently press the frosting into the sprinkles until completely coated.
Lift and shake off any excess sprinkles.
Allow the frosting to set for 20 to 30 minutes before serving.
Notes
These Dot Cake Cookies are designed to look just like classic bakery sprinkle cookies with a soft vanilla sugar cookie base, thick vanilla frosting, and a complete coating of colorful rainbow nonpareils. Follow these tips for the best flavor, texture, and appearance.
Use Room Temperature Ingredients
Room temperature butter, eggs, and sour cream blend together more easily and create a smoother cookie dough. This helps produce soft, evenly baked cookies with a tender crumb.
Measure Flour Correctly
Too much flour can make sugar cookies dry and dense. For the most accurate results, measure the flour by weight using a kitchen scale. If measuring by cups, spoon the flour into the measuring cup and level it off with a knife.
Chill the Dough
Chilling the dough for 30 minutes helps prevent excessive spreading and creates thick bakery-style cookies. This step is especially important for achieving the soft, puffy texture that works best with frosting.
Do Not Overbake
The cookies should remain pale when they come out of the oven. Overbaking can make them dry and crumbly. The centers should look set, but the tops should not develop much color.
Use Clear Vanilla for the Frosting
Clear vanilla extract gives the frosting a bright white appearance and creates the classic bakery-style birthday cake flavor found in many frosted sugar cookies.
Coat the Frosting Completely
For the signature Dot Cake Cookie appearance, spread a generous layer of frosting over each cookie and press the frosting directly into a bowl of rainbow nonpareils. This creates a colorful coating of sprinkles across the entire surface.
Allow the Frosting to Set
After dipping the frosting into the sprinkles, allow the cookies to rest for 20 to 30 minutes. This helps the frosting firm up and keeps the sprinkles in place.
Storage Tips
Store the cookies in an airtight container at room temperature for up to 4 days. Place parchment paper between layers to protect the frosting and sprinkle coating.
Freezing Instructions
Unfrosted cookies can be frozen for up to 3 months. Thaw completely before frosting and decorating with the rainbow nonpareils. For the freshest appearance, add the frosting and sprinkles just before serving.
Flavor Variations
For a stronger birthday cake flavor, add a little extra almond extract to the cookie dough and frosting. You can also swap the rainbow nonpareils for pastel sprinkles, holiday-colored sprinkles, or themed sprinkle mixes to match any celebration.
