Instructions

1. Cream 1 cup softened butter and 1 cup brown sugar in a large mixing bowl for 2-3 minutes until the mixture looks light and fluffy.
2. Incorporate 2 large eggs individually, beating thoroughly after each addition. Mix in 2 teaspoons vanilla extract until the batter feels smooth.
3. Separately combine 2 ½ cups flour, 1 teaspoon baking powder, ½ teaspoon salt, and 2 teaspoons instant coffee powder by whisking them together.
4. Merge dry ingredients into wet mixture, stirring minimally to prevent overmixing. Your dough should appear slightly dense and cohesive.
5. Gently fold 1 cup semi-sweet chocolate chips throughout the dough, ensuring even distribution.
6. Transfer the dough into a parchment-lined 9×13 inch pan, pressing and smoothing the surface with a spatula for an even layer.
7. Position the pan in a 350°F oven and bake for exactly 22-25 minutes. Your bars are ready when edges turn golden and a toothpick reveals moist crumbs.
8. Remove from oven and allow bars to rest in the pan for 10 minutes. Use parchment edges to transfer onto a wire cooling rack.
9. After complete cooling, slice into square portions. Serve at room temperature to appreciate the rich chocolate and subtle coffee undertones.

Notes

• Toast the instant coffee powder lightly in a dry skillet before adding to the dry ingredients to enhance the coffee’s depth and release its rich aroma.
• Always check bars slightly early, since oven temperatures vary and over-baking can lead to dry, crumbly texture instead of soft, fudgy centers.
• For a gluten-free version, swap all-purpose flour with a cup-for-cup gluten-free blend and add an extra tablespoon of flour to maintain the right consistency.
• Chill the dough for 30 minutes before baking to prevent excessive spreading and ensure thick, chewy bars with crisp edges.
