Lemon Lime Cake packs fresh zest and juice from both citrus twins into a buttery, tender loaf with a tangy glaze soaked into the top, and the first time I baked one on a warm May evening the whole thing vanished before it finished cooling. If my lemon cupcakes are your idea of sunshine, this cake is the loaf pan version of that feeling.
One bowl, one loaf pan, and two kinds of citrus doing all the flavor work.

Why This Recipe Works
Click to see the technique science
- Eight full minutes of creaming is not a typo. That long whip dissolves the sugar and beats air into the butter, which is exactly where this snack cake gets its light, fine crumb without any cake flour.
- Zest carries the flavor, juice carries the tang. Citrus oils live in the zest, so a full tablespoon in the batter perfumes every bite while the juice brightens without making the batter watery.
- Alternating flour and milk protects the crumb. Adding them in stages keeps the batter emulsified and prevents overworked gluten, tender cake instead of tough.
- Both citrus, not just lemon. Lime brings a floral sharpness that plain lemon cakes miss, together they taste like a citrus grove instead of a candle.
- Rotating the pan halfway evens the bake. Loaf pans sit close to oven walls, a 180 degree turn at 20 minutes keeps one side from browning ahead of the other.
- Glazing a cooled cake means the glaze stays put. On a warm loaf the glaze vanishes into the crumb, on a cooled one it soaks the top layer and sets into a sweet tangy crust.
Why You’ll Love This Recipe
- Double citrus flavor in an easy loaf, no layers, no frosting skills, no drama.
- The tangy glaze soaks into the top and forms that sweet crackly crust everyone fights over.
- It has the tender crumb of my yellow cake with a bright citrus glaze soaked in.
Key Ingredients
Simple pantry staples plus two pieces of fruit, that is the whole cast.
- Butter: The base. One softened stick creamed until fluffy gives the cake its rich flavor and fine crumb.
- Lemon and Lime Zest: The flavor engine. A full tablespoon of mixed zest carries the citrus oils through every slice.
- Lemon and Lime Juice: The tang. Fresh squeezed, split between the batter and the glaze.
- All Purpose Flour and Baking Powder: The structure. Nothing fancy, just enough lift for a tender snack cake.
- Powdered Sugar: The glaze. Whisked with citrus juice and vanilla into a pourable finish that sets slightly as it cools.

Variations and Substitutions
The citrus loaf formula bends any direction you like.
- All lemon or all lime: Use a single citrus for a classic lemon loaf or a margarita adjacent lime version.
- Orange twist: Swap half the zest for orange for a sweeter, mellower cake.
- Poppy seed: Stir a tablespoon of poppy seeds into the batter, citrus and poppy seed never miss.
- Berry topped: Spoon macerated strawberries over each slice like a citrus twist on my lemon blueberry poke cake.
- Cream cheese glaze: Whip two ounces of cream cheese into the glaze for a thicker, tangier topping.
How to Make Lemon Lime Cake
- Preheat the oven to 350 degrees. Cream the butter and granulated sugar together for a full 8 minutes with a hand or stand mixer, until light in color and fluffy.
- Add the egg and the mixed lemon lime zest and beat another minute until fully combined. In a separate bowl, stir together the flour, baking powder, and salt.
- Add a third of the flour mixture and beat to combine, then half the milk. Repeat with another third of flour, then the remaining milk plus 1 tablespoon of mixed citrus juice and the vanilla, then the last of the flour, beating about a minute and scraping the bowl between additions. Scrape the light, fluffy batter into a greased loaf pan.
- Bake for 20 minutes, rotate the pan 180 degrees for even cooking, and bake about 20 minutes more, until a toothpick inserted in the center comes out clean.
- Cool the cake in the pan on a wire rack for 20 minutes, then turn it out and cool completely. Whisk the powdered sugar, remaining citrus juice, and vanilla together and pour the glaze evenly over the cake. Finish with a dusting of powdered sugar and slice.
Recipe Tips & Tricks
- Do not shortcut the 8 minute cream. Set a timer, the batter should look almost white and noticeably fluffy, that air is the leavening insurance.
- Zest before you juice. A juiced lemon is impossible to zest, always grab the zest first while the fruit is firm.
- Zest only the colored skin. The white pith underneath is bitter, light pressure on the microplane keeps the flavor sweet and floral.
- Scrape the bowl between additions. Butter hides at the bottom, a quick scrape each time keeps the batter evenly mixed.
- Check at 35 minutes. Ovens vary, if the top is deep golden but the toothpick shows wet batter, tent loosely with foil for the last stretch.
- Glaze on the rack with a tray underneath. The drips fall through instead of pooling, and the tray catches them for the baker to taste test.
Serving Ideas and Suggestions
This is a true snack cake, park it on the counter under a cake dome and watch slices disappear with afternoon coffee, after school snacks, and midnight refrigerator raids. For a citrus dessert table, set it next to my mini no bake key lime pies and watch the sunshine theme come together.
Dress it up for company with fresh berries and a dollop of whipped cream, the tart glaze against sweet strawberries is a warm weather dessert that never misses. It plays beautifully at brunch beside a square of my lemon blueberry coffee cake.
It travels like a champ too, the sturdy loaf shape makes it the cake to bring to potlucks, picnics, and new neighbor doorsteps. For a layered dessert spread, my lemon blueberry trifle brings the showpiece energy.
And for a summer barbecue finish, serve thin slices with a scoop of vanilla ice cream and a little extra zest grated over the top.
Lemon Lime Cake FAQs
Lemon lime cake tastes like a bakery lemon loaf with an extra dimension, the lemon brings the familiar sunny tartness while the lime adds a floral, almost tropical sharpness underneath. The cake itself is buttery and tender from the long creaming, and the glaze concentrates the citrus into a sweet tangy top layer. It reads brighter than a plain lemon cake without being sour, kids love it and adults go back for seconds.
Fresh fruit makes a noticeably better lemon lime cake, mostly because you need the zest, and only fresh fruit has it. The zest carries the citrus oils that flavor the crumb, the juice mainly brings tang. If you are stuck, bottled juice works in the glaze in a pinch, but do not skip the fresh zest in the batter, one lemon and one lime gives you exactly enough of both zest and juice for the whole recipe.
A dense lemon lime cake almost always means the creaming step got shortchanged. This recipe leans on a full 8 minutes of beating butter and sugar to build the air that lightens the crumb, two minutes will not do it. Cold butter is the other culprit, it will not whip properly, so let it soften on the counter first. Finally, mix gently once the flour goes in, overbeating at that stage develops gluten and toughens the cake.
Store lemon lime cake covered at room temperature for up to 3 days, the glaze acts as a light seal that keeps the crumb moist. For longer, refrigerate up to a week, though the crumb firms when cold, so let slices sit out 20 minutes before serving. The cake also freezes beautifully, wrap the cooled unglazed loaf tight in plastic and foil for up to 3 months, then thaw overnight and glaze fresh before serving.
Yes, this lemon lime cake batter is flexible. An 8×8 square pan bakes in roughly 25 to 30 minutes and makes tidy snack squares, a dozen cupcakes take about 18 to 20 minutes, and doubling the recipe fills a bundt pan in the 45 to 55 minute range. Whatever the pan, the toothpick test is the referee, bake until it comes out clean and rotate halfway for an even golden top.
Not this one, this lemon lime cake gets its flavor from fresh lemon and lime zest and juice rather than lemon lime soda. Soda cakes like 7UP pound cake use the soft drink for lift and a subtle citrus note, but fresh zest delivers much bigger, brighter flavor. If you are curious, you can substitute the milk with lemon lime soda for a fun retro twist, but I would keep the fresh zest either way, it is the soul of the cake.
