Starbucks Lemon Loaf Recipe
Lemon is one of my all-time favorite flavors for desserts… besides chocolate, of course! It’s light and refreshing with just enough tartness to keep it from being too sweet.
Whether it’s as simple as a dump cake, or something a bit more sophisticated — say, a lemon cream cake just like Olive Garden’s — there’s no shortage of recipes to let that citrus flavor shine.
Despite my own very excellent (if I do say so) pound cake loaf, readers have been begging for a copycat Starbucks recipe for lemon loaf… and it’s finally here!
What sets it apart is a sweet, buttery glaze that crusts beautifully over the top, providing an extra burst of flavor in every bite. Yum!
Ingredient Notes and Substitutions
- All-purpose Flour – Keep it simple for a dense yet tender crumb.
- Baking Soda & Baking Powder – You’ll need both to get enough lift!
The baking powder works with the lemon juice for the initial rise, then the baking powder keeps it fluffy while it bakes. - Fresh Lemons – Use both the juice and the zest in this Starbucks lemon loaf recipe.
- Unsalted Butter – If you only have salted sticks on hand, omit the salt in both the cake and the glaze.
- Vanilla Extract – Adds a touch of warmth and sweetness to the loaf and the glaze. Replace half of this in the cake with almond extract if you’d like!
- Sour Cream – It may sound strange, but sour cream is the secret weapon for adding tons of moisture to this Starbucks recipe for lemon loaf.
Plus, it keeps the crumb extra tender.
Feel free to substitute with plain Greek yogurt instead.
Tips for Making Perfect Starbucks Lemon Loaf at Home
- Fully cream the butter and sugar together.
This takes longer than you might think! It’s not enough for the butter and sugar to be combined — you need to whip some air into the mixture for a fluffy cake texture.
Watch for the butter to lighten in color to a very pale yellow. The texture will be a bit fluffy too. Only then should you start adding the eggs!
- Use lemon extract to boost the flavor.
You have a few options here: Replace half of the vanilla extract with lemon, or add up to 1 teaspoon of lemon extract in addition to the vanilla.
Or, simply increase the amount of juice and zest. Just know that the extra acidity might affect the texture of the cake.
Keep in mind that the glaze adds more lemony goodness, so you may want to try the Starbucks recipe for lemon loaf as written.
If it’s not enough, you can make adjustments for the next one!
- Cover with foil if it browns too quickly.
If the top is looking dark but the center is still raw, loosely cover the pan with foil so it doesn’t burn.
Baking on the center rack will help prevent this, or move it down one if the heat comes from the top of your oven.
- Allow the loaf to cool in the pan for at least 10 minutes.
This helps it firm up slightly so you can transfer it to the wire rack without it falling apart.
Don’t let it sit in the pan for too long, though — it will continue baking and end up dry. It should finish cooling on the wire rack where cooler air can circulate around the entire loaf.
Prep Ahead
- Bring butter and eggs to room temp
- Preheat oven to 325°F
- Juice and zest lemons
Kitchen Tools You Will Need
- 9×5-inch Loaf Pan – Keep in mind that glass and dark metal bread pans bake hotter. So, you may want to lower your oven temperature by 25 degrees if using one of these.
- Stand mixer or large mixing bowl with Hand Mixer. You can’t properly cream the butter and sugar without one!
- Citrus Juicer and Zester for maximum lemon flavor.
- Mixing Bowls – I like to have a variety of sizes on hand, and this set has them all.
- Wire Rack – Great for cooling all kinds of baked goods. I like to add a Small Baking Sheet or a piece of Parchment Paper underneath to catch any drips from the glaze!
Serving Suggestions
No Starbucks lemon loaf would be complete without that sweet glaze topping!
And when you make your own homemade version, you can add a little bit more – and more – and more! (that’s the best part of creating in the kitchen!)
Powdered sugar and milk form the base, while melted butter helps it crust over on top instead of soaking right into the surface.
Use freshly squeezed lemon juice and vanilla extract to flavor the mixture, plus a pinch of salt to balance the sweetness.
Then, spoon the glaze over the loaf while it’s still slightly warm.
Once your copycat Starbucks lemon loaf is completely cool, it’s ready for slicing! Don’t be tempted to slice any sooner or it will crumble apart.
The glaze should also be completely dry so it doesn’t ooze everywhere.
Enjoy a slice or two with tea or coffee — maybe even an iced coffee with sweet cream cold foam in the summer.
It also makes a refreshing snack or light dessert, much like my blueberry lemon cake!
Storing and Freezing Copycat Starbucks Lemon Loaf
Keep Starbucks lemon loaf at room temperature for 4 to 5 days — an airtight container will help keep it moist.
Avoid storing it in the refrigerator as the cold air will dry out the cake faster.
For longer storage, you can also freeze the whole loaf or individual slices for a quick snack! It will keep for up to 6 months, whether frosted or plain.
- With Glaze: Place whole loaf or slices on a baking sheet and freeze for 2-3 hours.
Then, wrap in plastic wrap and foil before storing in a freezer-safe bag or container. - Without Glaze: No need to flash freeze first! Just wrap in layers once cooled, then label and store.
Starbucks Recipe for Lemon Loaf FAQ
Once mixed, the lemon glaze should have a smooth, pourable consistency that doesn’t run right off the spoon. It helps to let the melted butter cool a bit before mixing it with the other ingredients.
If it’s too thin, add more powdered sugar. Too thick means you need more liquid, preferably more milk.
While I certainly love boxed mix shortcuts, I don’t recommend it for this Starbucks lemon loaf recipe. The texture is closer to a pound cake, so you need that extra butter for the base of the batter.
Avoid overmixing the batter and don’t overbake the cake either. Insert a toothpick into the center to test for doneness — it should come out with a few moist crumbs. If it’s dry, your Starbucks lemon loaf is overdone.
Keep any leftovers at room temperature in an airtight container. Exposure to air will dry it out faster, as will storing it in the refrigerator.
Enjoy!

Starbucks Lemon Loaf Copycat
Ingredients
- 6.5 ounces all-purpose flour, about 1 1/2 cups, spooned and leveled
- 1/4 teaspoon kosher salt
- 1/4 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/2 cup unsalted butter, softened to room temperature (1/2 cup or 1 stick)
- 1 cup granulated sugar
- 3 large eggs, at room temperature
- 2 tablespoons fresh lemon zest, about 2 medium lemons, zested
- 1 tablespoon fresh lemon juice, about 1/2 medium lemon, juiced
- 2 teaspoons pure vanilla extract
- 1/3 cup full-fat sour cream
LEMON GLAZE
- 1 1/2 cups powdered sugar, sifted
- 1 tablespoon fresh lemon juice, about 1/2 medium lemon, juiced
- 1 tablespoon whole milk
- 1 tablespoon unsalted butter, melted
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon kosher salt
Instructions
- PREHEAT OVEN AND PREP PAN: Preheat the oven to 325 degrees F (about 10 minutes). Coat a 9×5-inch loaf pan with non-stick spray and line the bottom and long sides with a sling of parchment paper. The parchment lets you lift the cooled loaf out cleanly later.
- WHISK THE DRY INGREDIENTS: In a medium bowl, whisk together 6.5 ounces all-purpose flour, 1/4 teaspoon kosher salt, 1/4 teaspoon baking soda, and 1/4 teaspoon baking powder for about 30 seconds until evenly blended. Set aside.
- CREAM THE BUTTER AND SUGAR: In a large bowl, cream 1/2 cup unsalted butter and 1 cup granulated sugar with an electric mixer on medium speed for 3 to 4 minutes. The mixture should turn pale yellow, look fluffy, and triple in volume. This step builds the structure that gives the loaf its tender crumb.
- BEAT IN THE EGGS: Add 3 large eggs room-temperature one at a time, beating for about 30 seconds after each addition until the batter looks smooth and the egg is fully incorporated. Scrape the bowl between eggs so nothing hides at the bottom.
- STIR IN LEMON AND VANILLA: Stir in 2 tablespoons fresh lemon zest, 1 tablespoon fresh lemon juice, and 2 teaspoons pure vanilla extract. The aroma jumps the moment the zest hits the warm batter.
- FOLD IN FLOUR AND SOUR CREAM: Add the dry ingredients in three additions, alternating with 1/3 cup full-fat sour cream in two additions, starting and ending with the flour mixture. Fold gently with a spatula after each addition for about 10 seconds. Stop the moment no flour streaks remain. The batter should look thick, glossy, and a little lumpy.
- POUR AND BAKE: Scrape the batter into the prepared loaf pan and smooth the top with a spatula. Bake on the center rack for 45 to 55 minutes. The loaf is ready when the top is golden, a wooden skewer inserted in the center comes out with just a few moist crumbs, and the kitchen fills with a warm lemon-vanilla aroma.
- COOL IN THE PAN: Remove the pan from the oven and set on a wire rack. Let the loaf rest in the pan for 10 minutes. Then lift the loaf out using the parchment sling and transfer to the rack to cool for another 20 minutes.
- MAKE THE GLAZE: While the loaf cools, whisk 1 1/2 cups powdered sugar, 1 tablespoon fresh lemon juice, 1 tablespoon whole milk, 1 tablespoon unsalted butter, 1 teaspoon pure vanilla extract, and 1/4 teaspoon kosher salt in a small bowl for about 1 minute. The glaze should be smooth, opaque white, and thick enough to ribbon off the whisk and hold a line for 2 seconds before melting back in.
- GLAZE AND SET: Set the wire rack with the warm (not hot) loaf over a rimmed baking sheet or parchment paper to catch drips. Spoon the glaze over the top, letting it cascade down the sides. Let the loaf rest 30 minutes for the glaze to set into a soft, opaque shell. Slice and serve.
