Follow these simple steps to create your Chai Latte Blondies:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper for easy removal.

2. Mix Wet Ingredients: In a large bowl, combine the melted butter, brown sugar, and granulated sugar. Whisk until smooth. Add the eggs and vanilla extract, mixing well.

3. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, baking soda, salt, and spices (cinnamon, ginger, cardamom, and nutmeg).

4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.

5. Add Chocolate Chips: If desired, fold in the white chocolate chips and/or nuts for added texture and flavor.

6. Pour Into Pan: Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.

7. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

8. Cool: Once baked, remove the blondies from the oven and allow them to cool in the pan for about 10-15 minutes. Then transfer to a wire rack to cool completely.

9. Cut and Serve: Once cooled, cut the blondies into squares and serve.
