Lemon Loaf Cake

Learn how to make this beautiful lemon loaf cake with this easy recipe. This cake is very moist and tender, made with sour cream. The lemon drizzle and icing on top add a ton of lemon flavour and ensure it stays moist.

A lemon loaf cake is a weeknight staple for breakfast, snacks, or even dessert. Like most quick breads, you can use the creaming mixing method to combine the ingredients. This allows you to incorporate more air into the batter, leading to a more delicate crumb.

Ingredients to Make Lemon Cake

If you want to make a lemon bread, you will need the following ingredients:

• granulated sugar—though brown sugar could also work here, it would add a molasses flavour that may overpower the delicate lemon flavour of the cake. Stick to granulated or caster sugar!
• lemon zest, which adds lemon flavour to the batter without adding extra liquid. You will mix the zest with the sugar first to help draw out the lemon oil from the peel to flavour the cake (this is how you make lemon sugar!)
• butter, preferably unsalted butter because you will add salt to the batter, but if you have salted, it will work. Just adjust the salt in the recipe accordingly, otherwise your cake may be too salty
• large eggs, don't use smaller eggs because your cake may be too dry, but don't use extra large eggs because they could affect the texture of the cake. Sometimes eggs can toughen a cake!
• vanilla extract is a great complement to lemon flavour, but you could also try lemon extract or even lemon oil to bring even more flavour to the cake
• cake flour, lower in protein and higher in starch, will give the cake a delicate, finer crumb that you would expect from a lemon loaf
• baking powder and baking soda are needed in this recipe. The baking soda is a base (alkaline) and balances out the acidity of the sour cream in the batter, while baking powder helps the cake rise up. Read up on baking soda vs baking powder if you are unsure
• salt is really important to balance out the sweetness. Don't skip it. I like to use Diamond Crystal fine kosher salt, but table salt will work, though the cake will be a touch saltier and you may want to halve the salt in that case.
• sour cream (full-fat) helps tenderize the cake and also the fat contributes to preventing the cake from going stale so quickly
• lemon juice (freshly squeezed) is the secret to bringing the mouth-puckering tanginess we expect from lemon desserts. While the zest is added to the cake batter to bring lemon flavour to the crumb, we use lemon juice in a simple syrup that you brush onto the hot cake to help infuse the crust with a burst of flavour.
• icing sugar is needed to make the icing for this cake. You can't replace it with regular white sugar because it's too coarse and we need a fine powdered sugar to make a smooth icing.

Special Tools and Equipment

Loaf cakes and quick breads don't require anything special. We are using the creaming method to make this lemon cake. Using a stand mixer makes it easier for you to mix the ingredients well and incorporate more air into the batter, leading to a finer crumb.

This recipe will fit in any 6-cup cake pan. You can use an 8.5" x 4.5" loaf pan or even a 9" x 5" (1 pound loaf pan). For the photos, I used a fluted loaf pan from Nordic Ware. It has an elaborate pattern, reminiscent of bundt pan shapes. By all means, use the loaf pan you already have in your cupboard, but the look will be different.

You will also need a pastry brush to brush the syrup onto the surface of the hot cake.

Infusing Baked Goods with Lemon Flavour

There are four main ways of infusing baked goods with lemon flavour:

1. lemon zest— the outermost layer of the citrus peel
2. lemon juice—freshly squeezed has a better flavour than bottled
3. lemon extract—either real lemon extract (preferably) or artificial, alcohol–based
4. lemon oil—an oil-based extract coming from the natural oils from lemon peel

For this lemon cake, we are using lots of lemon zest in the cake batter. We save the fresh lemon juice to make the lemon syrup to brush onto the warm cake to infuse it. Once cooled, we make a lemon icing with even more lemon juice to bring it all together.

You can definitely test out lemon oil or lemon extract in this recipe, but I haven't tried it yet. I don't have either of these ingredients, and I assume most bakers don't either. For this reason, I stuck to using fresh lemons for flavour in this recipe.

Trick for Thick Icing

For simple icings that are made of mostly powdered sugar (icing sugar) with a liquid, the key is to add very little liquid so that they don't become runny. For 60 grams (½ cup) of icing sugar, we only add 15 mL (1 tablespoon) of lemon juice. The icing is so thick that you have to spoon it onto the top of the cake. Then to achieve decorative drips, you have to nudge it over the edges.

The amount of liquid really doesn't seem like enough when you are mixing it with the icing sugar. However, if you use a small whisk, you can achieve a very smooth consistency. Make sure to work the two ingredients together until they form a thick paste.

Other Loaf Cakes to Try

Loaf cakes are a real treat during the week. They come together quickly. You can dress them up to make them fancy if need be for a dinner party or family dinner. If lemon cake isn't your favourite, you can try this chocolate loaf cake, topped with vanilla bean ice cream. Or, during the fall, make this pumpkin bread with cranberries!

Storage Suggestions

Loaf cakes will last several days at room temperature if you store them on a board, wrapped in aluminum foil. For longer storage, the freezer is your best bet. You can store the loaf, without icing in the freezer for several months (up to 3 months). Unwrap the frozen cake and then defrost it in the fridge overnight to avoid the surface becoming gummy. Then make the icing the next day to decorate it.
