# What You'll Need:
→ 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
# How-To Steps:
01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large bowl, whisk together flour, sugar, baking powder, and salt until well combined.
03 - Add cold, cubed butter. Using a pastry cutter or fingertips, blend until the mixture resembles coarse crumbs.
04 - Add the egg and vanilla extract. Mix until combined and a crumbly dough forms.
05 - Press about two-thirds of the dough evenly into the prepared pan to form the base.
06 - Gently spread the 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 streusel topping.
08 - Bake for 35–40 minutes, or until the top is lightly golden.
09 - Cool completely in the pan before lifting out and cutting into bars.
