Cream Butter & Sugar: In a large bowl, cream together the softened butter and granulated sugar for 2–3 minutes until the mixture is light, pale, and fluffy.
Add Wet Ingredients: Beat in the egg, vanilla extract, and almond extract until fully combined and smooth.
Mix Dry Ingredients: Gradually add the flour, baking powder, baking soda, and salt. Mix on low speed until a soft dough forms.
Add Sprinkles: Gently fold in the 100g of sprinkles with a spatula until evenly distributed.
Chill: Cover the bowl and chill the dough in the refrigerator for at least 30 minutes. This prevents the cookies from spreading too thin.
Preheat & Shape: Preheat your oven to 180°C (160°C fan). Line two baking sheets with parchment paper. Scoop the dough into balls (about 2 tablespoons each), place them on the sheets, and flatten them slightly with your palm.
Bake: Bake for 12–15 minutes, or until the edges are just barely golden. The tops should still look soft and pale. Let them cool completely on a wire rack.
Make Frosting: In a medium bowl, beat the softened cream cheese and butter until smooth. Add the powdered sugar, vanilla, salt, and heavy cream. Whisk until creamy and light.
Frost & Decorate: Spread a thick layer of frosting over the cooled cookies and top with extra sprinkles before the icing sets.
