Tips
Cream butter and sugar until visibly light and fluffy, about 2-3 minutes, to incorporate air for a tender crumb.
Do not overmix the dry ingredients into the wet mixture; stop as soon as streaks disappear to prevent tough, dense texture.
Ensure dough is pressed into an even thickness on the pan so all edges bake at the same rate.
Good to Know
Cover cooled, unfrosted crust tightly and store at room temperature for up to 2 days, or refrigerate for up to 4 days. Top shortly before serving for best texture.
Prepare and chill dough up to 2 days ahead. Bake up to 1 day ahead and store unfrosted. Add toppings the day of service.
Serve at room temperature. Cut into squares or rectangles after topping. Pairs well with coffee, tea, or milk.
Common Mistakes
Overmix dry ingredients into wet mixture to avoid a tough, dense cookie texture.
Skip the chill time to avoid spreading too thin and losing tender structure.
Use cold butter or egg to avoid breaking the emulsion during creaming.

FAQ
Can I make this without vanilla paste?
Yes, substitute 1 teaspoon vanilla extract, though paste provides more concentrated flavor. Add it with the egg rather than separately, and reduce any other liquid accordingly.
What if my dough is too sticky to roll?
Ensure your butter was softened, not melted. If dough is still sticky, chill it for 15 minutes before attempting to roll. Use parchment on both sides while rolling.
How long can I keep the baked crust before topping?
Unfrosted crust stays fresh at room temperature for 2 days covered, or refrigerated for up to 4 days. Do not freeze unfrosted. Top the day of service for best texture.
