Pistachio Pudding Sugar Cookie Bars

Store any leftover bars in an airtight container at room temperature for up to 3–4 days. The bars will remain soft and flavorful thanks to the moist texture from the pudding mix.
For a richer flavor, you can replace the vanilla extract with almond extract, which pairs beautifully with the pistachio flavor.
If you prefer a nut-free version, you can skip the pistachio garnish and use sprinkles for decoration.
These bars also freeze well. Once cooled and frosted, wrap them tightly in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw before serving.
