How to Make Starbucks-Style Lemon Loaf Cake

Step 1: Prep the Oven

Preheat your oven to 350°F (175°C). Grease and line a standard loaf pan with parchment paper, leaving an overhang for easy removal.

---

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together:

• Flour
• Baking powder
• Salt

Set aside.

---

Step 3: Make the Lemon Batter

In a large bowl, whisk together the sugar and eggs until pale and slightly thickened. Slowly whisk in the oil, followed by the sour cream, lemon zest, lemon juice, and vanilla extract.

The batter should be smooth, glossy, and fragrant with lemon.

---

Step 4: Combine & Bake

Gently fold the dry ingredients into the wet mixture until just combined. Do not overmix—this keeps the loaf tender and soft.

Pour the batter into the prepared loaf pan and smooth the top.

Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

---

Step 5: Cool Completely and Add Glaze

Allow the loaf to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before frosting. Add your lemon syrup to your warm cake and then let cool.

How to Make Matcha Vanilla Frosting

In a small bowl, whisk together:

• Powdered sugar
• Matcha powder
• Vanilla extract

Add milk or cream 1 tablespoon at a time until you reach a thick but pourable glaze consistency.

The frosting should be smooth, lightly green, and subtly earthy—not bitter.

---

Frost the Loaf

Once the lemon loaf is fully cooled, spoon or drizzle the matcha vanilla frosting over the top, letting it naturally drip down the sides.

Allow the frosting to set for 10–15 minutes before slicing.

Frequently Asked Questions

Does this really taste like the Starbucks lemon loaf?

---

Can I skip the matcha?
