I make this Lemon Lime Bundt Cake whenever I need something bright, unfussy, and crowd-pleasing. It’s the kind of cake that shows up at potlucks and gets wiped out by the end of the night. The citrus keeps it from feeling too sweet while the frosting gives it the right amount of indulgence.

This recipe leans on a store-bought white cake mix and a tub of frosting—deliberate shortcuts that save time without sacrificing flavor. A few fresh ingredients (sour cream, citrus zest, a splash of juice) change the whole profile and make the cake taste homemade rather than boxed.

The method is straightforward: mix, bake, thin the frosting with lemon and lime, and drizzle. I’ll walk you through the small details that make a bundt look and slice well, plus swap ideas and troubleshooting so you get the best results every time.

What You’ll Gather

Below are the exact ingredients called for in the recipe and a brief note about each—why it’s there and a tip to get the best result.

Ingredients

1 package Pillsbury™ White Cake Mix — base for the cake; choose the white variety for a neutral, bright crumb that lets the citrus shine.
1 cup sour cream — adds moisture and a slight tang that keeps the cake tender and prevents dryness.
1/2 cup oil — keeps the cake moist and improves shelf life; neutral vegetable oil works well.
4 eggs — provide structure and richness; use room-temperature eggs for even mixing.
1 teaspoon finely grated lemon peel — concentrated lemon flavor; grate only the yellow part of the peel to avoid bitterness.
1 teaspoon finely grated lime peel — adds a bright counterpoint to the lemon; zest finely so it disperses through the batter.
1 teaspoon lemon juice — touches up the batter’s acidity and helps highlight the citrus notes.
1 Can Pillsbury Creamy Supreme Vanilla Frosting — used as the glaze base; warming it and thinning with citrus creates a glossy drizzle.
2 teaspoons lemon juice — thins and flavors the frosting; use fresh for best brightness.
2 teaspoons lime juice — pairs with lemon to round out the frosting flavor and add a hint of tang.

From Start to Finish: Lemon Lime Bundt Cake

Preheat oven to 350°F. Coat a 12-cup bundt pan or 10-inch fluted tube pan with nonstick cooking spray and dust with flour, tapping out any excess.
In a large bowl, add 1 package Pillsbury™ White Cake Mix, 1 cup sour cream, 1/2 cup oil, 4 eggs, 1 teaspoon finely grated lemon peel, 1 teaspoon finely grated lime peel, and 1 teaspoon lemon juice. Using an electric mixer, beat on low speed 1 minute or until moistened, then beat on medium speed 2 minutes. Scrape sides of the bowl as needed.
Spread the batter evenly in the prepared pan.
Bake 40 to 44 minutes or until a toothpick inserted in the center comes out clean. Cool in the pan 15 minutes, then remove the cake from the pan and place on a wire rack to cool completely.
Place the entire can of Pillsbury Creamy Supreme Vanilla Frosting in a microwave-safe bowl. Add 2 teaspoons lemon juice and 2 teaspoons lime juice. Microwave 20–40 seconds, then stir until smooth. If needed, microwave additional 10-second increments until the frosting reaches a drizzleable consistency.
Drizzle the flavored frosting over the completely cooled cake. Let the frosting set before slicing and serving.

Why This Recipe Belongs in Your Rotation

It’s fast without tasting rushed. Using a boxed mix and ready-made frosting keeps the steps minimal, but the sour cream and fresh zest give the cake texture and personality that boxed recipes often lack. If you need a last-minute dessert that still feels thoughtful, this one delivers.

It slices cleanly, travels well, and suits casual and slightly dressier occasions. The citrus keeps it from feeling heavy, so it works for spring brunches, summer cookouts, or any time you want something bright after dinner.

Dairy-Free/Gluten-Free Swaps

If you need to avoid dairy or gluten, simple substitutions keep the spirit of the cake intact. Note that these swaps will alter texture slightly, but they’re practical options.

Dairy-free sour cream: Use a plant-based sour cream or a thick coconut-based yogurt in the same amount. It gives similar moisture and tang.
Frosting: Look for a dairy-free frosting tub or make a simple glaze from powdered sugar and citrus juice if you want to avoid the commercial frosting.
Gluten-free cake mix: Replace the white cake mix with a certified gluten-free white cake mix measured 1:1; baking times may vary slightly—start checking at the earlier end of the time range.

Cook’s Kit

These are the tools that make the job easier and the result more consistent.

12-cup bundt pan or 10-inch fluted tube pan — proper pan matters for baking time and release.
Nonstick cooking spray and flour — for greasing and dusting the pan so the cake releases cleanly.
Electric mixer — helps get a smooth, evenly aerated batter in the specified times.
Microplane or fine grater — for the lemon and lime peels so the zest is fine and evenly distributed.
Wire rack — essential for cooling the cake completely before glazing so the frosting doesn’t slide off.
Microwave-safe bowl and spatula — for thinning and stirring the frosting to a drizzleable consistency.
Toothpick — to test doneness at the center of the cake.

Mistakes That Ruin Lemon Lime Bundt Cake

A few common missteps crop up with bundt cakes. Avoid these and you’ll get a clean release, even crumb, and bright citrus flavor.

Not preparing the pan properly: Skip the spray-and-flour step and the cake can stick. Be thorough—get into the crevices.
Baking too long or at the wrong temperature: Oven temps vary. Start checking at the earlier time and use a toothpick for a reliable test.
Removing the cake too soon: Pulling it from the pan immediately risks breakage. Let it rest the full 15 minutes, then invert gently onto a rack.
Glazing a warm cake: If you drizzle frosting before the cake is completely cool, it will run and pool at the bottom instead of setting attractively.
Overmixing after adding eggs: Beat only as directed; overbeating can create a cakey, dense texture instead of tender crumb.

Seasonal Ingredient Swaps

Swap one or two items to tailor the cake for the season without changing the method.

Spring: Add a tablespoon of poppy seeds to the batter for a lemon-poppy lift.
Summer: Fold a half-cup of finely diced strawberries or raspberries into the batter very gently for a fruit studded cake—expect a slightly longer bake time.
Fall: Swap half the lemon and lime zest for orange zest and cut the citrus juices slightly to balance sweetness.
Winter: Add a pinch of cardamom to the batter for a warming, citrus-friendly spice note.

If You’re Curious

Little adjustments change texture and flavor depending on what you prefer. Want a denser, more pound-cake style texture? Use melted butter instead of oil, keeping the same amount, and still mix as directed. Prefer a lighter crumb? Be sure your eggs are room temperature and don’t overmix.

If the frosting feels too tangy after adding both juices, stir in a teaspoon of vanilla extract (not listed in the original ingredient list) to round it out. Use that tweak sparingly—this cake is meant to be bright.

Freezer-Friendly Notes

This bundt freezes well, whole or in slices. For best results:

Unfrosted freeze: Cool the cake completely, wrap it tightly in plastic wrap, then in foil. Freeze up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours before glazing.
Frosted freeze: Freeze the frosted cake uncovered for an hour to harden the glaze, then wrap tightly. Store up to 2 months. Thaw in the refrigerator to prevent condensation from making the glaze run.
Individual slices: Flash-freeze slices on a tray, then bag them for easy portions. Thaw in the fridge or microwave briefly until just warmed.

Helpful Q&A

Q: Can I make this in a loaf pan instead of a bundt?
A: Yes. Use two 9×5 loaf pans or one large bundt-sized loaf pan. Bake time will change—start checking at 35 minutes and expect up to 55 minutes depending on pan and oven.

Q: My cake stuck to the pan—what went wrong?
A: Most likely the pan wasn’t properly greased and floured, or it was removed too quickly. Use a nonstick spray that contains flour or rub with butter and dust flour into every cavity. Let the cake cool the full 15 minutes before turning out.

Q: Can I make the frosting from scratch?
A: Yes. A simple powdered sugar glaze (powdered sugar + citrus juice) can replace the tub frosting. The recipe as written uses the Pillsbury frosting to keep things quick and predictable.

Q: How do I get the zest fine enough?
A: Use a microplane grater and only grate the colored part of the peel. The white pith is bitter, so avoid it.

Ready, Set, Cook

This Lemon Lime Bundt Cake is a small victory: quick to mix, reliable to bake, and bright enough to feel like you went the extra mile. Follow the exact ingredient list and steps above for dependable results. Once it’s out of the oven and glazed, slice it up and watch it disappear.
