Ingredients

Gluten Free 1-to-1 Flour – 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. 

Salt

Sugar

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

Step by step instructions for making a lemon loaf cake.

How to Make an Iced Lemon Loaf

  • 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.

Frequently Asked Questions

Yes! When you’re making a cake, you are trying to create an emulsion between the fat and eggs.  You want the ingredients to combine effortlessly, so the air bubbles can be whipped in resulting in a light cake.

This iced lemon loaf should be stored in an airtight container at room temperature.  It will last 3-4 days. 

If you don’t have a stand mixer, a handheld mixer will do fine.  You will want to use an electric mixer of some sort though to make sure you get enough air into the batter for it to rise.

I don’t think this cake will work without eggs (or using an egg substitute).  It relies on the eggs for structure and lift and there are a lot of them in the recipe.

If you need an egg free or vegan version, I’d recommend looking for a recipe that’s been written for vegan baking.
