# Needed Ingredients:
→ Cookie Base and Streusel
01 - 2 cups all-purpose flour
02 - 1 cup granulated sugar
03 - 1/2 teaspoon baking powder
04 - 1/4 teaspoon salt
05 - 1 cup unsalted butter, cold and cubed
06 - 1 large egg
07 - 1 teaspoon vanilla extract
→ Filling
08 - 1 cup guava jam or guava paste, softened
# Steps:
01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang for easy removal.
02 - Whisk together flour, sugar, baking powder, and salt in a large mixing bowl.
03 - Add cold cubed butter to the flour mixture. Using a pastry cutter or fingertips, blend until mixture resembles coarse crumbs.
04 - Add egg and vanilla extract to the mixture. Blend until combined and a crumbly dough forms.
05 - Press approximately two-thirds of the dough evenly into the prepared pan to create the base layer.
06 - Gently spread guava jam over the base, leaving a small border around the edges.
07 - Crumble the remaining dough evenly over the jam layer to create a golden streusel topping.
08 - Bake for 35-40 minutes until the top is lightly golden brown.
09 - Allow bars to cool completely in the pan before lifting out and cutting into 16 equal bars.
