This copycat gluten free lemon loaf recipe is so moist and delicious. It is bursting with lemon flavor and that icing...
Why You'll Love This Lemon Loaf Cake
- It doesn't cost $3+ per slice.
- It's so moist.
- It's a lemon lover's dream.
- It uses real ingredients, no hard to pronounce chemicals.
- It's gluten free and dairy free!
- Gluten Free 1-to-1 Flour Blend - I use Bob's Red Mill 1-to-1 Flour Blend in all of my recipes. You can use the flour blend of your choice just make sure it has xanthan gum. Different flour blends may produce different results. For the best outcome, weigh your flour.
- Baking Powder - This leavening agent will help the cake come out soft and fluffy.
- Vegan Butter & Oil - This recipe uses a combination of butter and oil. The butter provides the richness of pound cake while the oil allows for more moisture to be used, resulting in a nice moist cake. If you're not dairy free, you can use regular butter in the same measure.
- Eggs - The eggs provide structure for the loaf. I haven't tried egg replacements with this recipe. If you do, let me know how it works in the comments.
- Vanilla - To provide some sweetness.
- Lemon Zest and Lemon Juice - The star of the recipe. No lemon extract is used here. You'll need 2 lemons for the cake and icing.
- Vegan Sour Cream - The sour cream helps keep the loaf moist. If your stores don't carry vegan sour cream, you can substitute dairy free yogurt or even milk. It might change the end result slightly, but it will still be delicious. If you're not dairy free, just use regular sour cream.
- Powdered Sugar

Substitutions & Variations
- Not Dairy Free - use dairy butter and sour cream in the same measure.
- Make it Vegan - This cake uses 3 eggs, which can be tricky to replace. I would try a combination of a baking soda + vinegar egg and some applesauce.
- No Lemons - Try replacing lemons with limes or oranges in the same measure.
- Make it Less Sweet / Lower Calorie - Omit the icing from the top of the lemon loaf.
How to Make an Gluten Free Lemon Loaf
This copycat lemon loaf is easy to make. For the best result, use an electric mixer.
STEP 1: Combine your lemon zest with the sugar. Use your fingers to rub the sugar and zest together. This imparts the oil from the lemon rind into the sugar making for a stronger lemon flavor.
STEP 2: Once your sugar is thoroughly mixed with the lemon, it will be light yellow in color.
STEP 3: Combine the butter, oil and lemon sugar in the bowl of an electric mixer and beat for 3 minutes until light and fluffy.
STEP 4: Add the vanilla and lemon juice. Then add the eggs one at a time, mixing for a minute between each addition.
STEP 5: Add half of the dry ingredients, followed by the sour cream. Then add the remaining dry ingredients.
STEP 6: Spread the batter into a lined loaf pan and bake!
How Do You Make Lemon Icing?
The icing on this cake makes it extra delicious. It's sweet and filled with lemon flavor.
Lemon icing is so easy to make. You combine powdered sugar and lemon juice and stir together until smooth. The icing will seem very thick, but that's what you want to get that copycat Starbucks lemon loaf cake.
Pour the thick lemon icing on top of the cooled cake and spread just to the edges with an offset spatula. It will naturally run down the sides a bit, but it should be thick enough to dry to the touch within about 30 minutes.
