Copycat Café Part 12: Starbucks Matcha Swirl Loaf

0 Preheat your oven to 350°F. Grease and line a loaf pan with parchment paper.
1 In a large mixing bowl, whisk together the flour, baking powder, and salt.
2 In a separate bowl, whisk together the melted butter, sugar, eggs, sour cream (or yogurt), and vanilla until smooth.
3 Add the wet ingredients to the dry ingredients and stir until just combined. Be careful not to overmix.
4 Divide the batter evenly among three bowls.
5 Mix the matcha powder into one bowl.
6 Mix the freeze-dried strawberry powder into the second bowl.
7 Leave the third bowl plain (or just do matcha and strawberry)
8 Spoon alternating dollops of the matcha, strawberry, and vanilla batters into the prepared loaf pan. Use a butter knife to gently swirl the colors together, then smooth the top.
9 Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
10 Allow the loaf to cool in the pan for about 5 minutes before transferring it to a wire rack to cool completely.
