1-First, combine 1 cup salted butter, ½ cup granulated sugar, and ¼ cup powdered sugar in a bowl until smooth and creamy this creates the base for your dough’s tender feel.

2-Mix in a pinch of table salt and 1 teaspoon vanilla extract to add that extra flavor boost, blending until everything is evenly incorporated.

3-Add 2 ¼ cups all-purpose flour and 1 tablespoon cornstarch (if you’re using it), mixing until just half combined, then gently fold in 3 tablespoons nonpareil sprinkles to keep them from breaking or bleeding color.

4-Press the dough into a ¼-inch thick rectangle on a parchment-lined baking sheet, and feel free to press on extra sprinkles for more fun. Pop it in the fridge for 30 minutes to chill this step is a game-changer to prevent spreading.

5-Preheat your oven to 375°F (190°C), then cut the chilled dough into ¼- to ½-inch squares and arrange them on parchment-lined baking sheets, spacing them out a bit.

6-Bake for 7-9 minutes until set, or go 1-2 minutes longer if you want them extra crispy keep an eye on them to get it just right!

7-Let the bites cool completely on the sheet before diving in, as this helps them firm up and stay delicious.
