Step-by-Step Instructions
1. Prep Your Pan and Oven
Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. Grease lightly to prevent sticking.
2. Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, salt, cinnamon, ginger, and cardamom. Set aside.
3. Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and brown sugar until light and fluffy. This step helps create a chewy, tender crumb.
4. Add Wet Ingredients
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla, cooled coffee, milk, and chai tea concentrate.
5. Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet, folding gently until fully incorporated. Be careful not to overmix.
6. Bake to Perfection
Pour the batter into the prepared pan and smooth out the top. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
7. Let Cool
Allow the bars to cool completely in the pan before icing. This is crucial for the icing to set properly.
8. Make the Icing
In a small bowl, whisk together the powdered sugar, chai concentrate, cinnamon, and vanilla until smooth. Adjust the thickness with a little more chai concentrate or sugar if needed.
9. Drizzle and Serve
Drizzle the icing over the cooled bars and let them set for 15 minutes before cutting into squares. Enjoy every gooey, spicy bite!
