What Are Matcha Blondies?

Matcha blondies are a variation of classic blondies made with matcha green tea powder instead of traditional brown sugar flavorings. The result is a rich, chewy dessert bar with a vibrant green color and subtle earthy notes balanced by sweet white chocolate.

Unlike brownies, blondies have a dense, buttery texture without cocoa powder, making matcha the perfect flavor addition.

Ingredients

1 box vanilla or yellow cake mix (15–16 oz)
1 can sweetened condensed milk (14 oz)
1/2 cup unsalted butter, melted
3 tablespoons culinary-grade matcha powder
1 cup white chocolate chips (optional but highly recommended)

How to Make Slow Cooker Matcha Blondies
