Pineapple plus lemon is a match made in heaven, and this lemon cake with pineapple filling is here to prove it! This is one of our favorite summer desserts, and I’m pretty sure your family will gobble it up as quickly as we do.
The lemon cake recipe transforms your standard boxed lemon cake mix into a crowd-pleasing, restaurant-worthy dessert -and it just so happens to be on the lighter side! You’ll use Greek yogurt and water to make the box of cake mix, resulting in a melt-in-your-mouth texture and an extra bit of protein in every slice.
As for the pineapple cream filling, it is a fuss-free mixture of lemon whipped cream frosting and pineapple tidbits, and you will probably (definitely) want to eat it straight from the spoon. That said, the lemon whipped cream frosting is made with lite whipped topping, sugar-free instant pudding, and low-fat milk -so I see no reason not to lick the spoon!

Why You'll Love This Recipe
- It’s downright delicious. Sweet, juicy pineapple complements citrus perfectly.
- Only FOUR ingredients for the cake and FOUR ingredients for the frosting!
- The ingredients are lower in fat and calories than classic lemon cake recipes, but you’d never know.
- The cake and frosting are semi-homemade but taste made from scratch.
Ingredients You'll Need

- Lemon Cake Mix: Use a box that you’ve had success with in the past or reliable cake mixes like Duncan Hines, Betty Crocker, Krusteaz, or Pillsbury,
- Greek Yogurt: This is the secret healthy ingredient that makes a box of lemon cake mix taste like it is homemade. You can also use sour cream here.
- Water: Helps thin the batter to the perfect consistency.
- Crushed Pineapple: I used a can of drained crushed pineapple, but pineapple tidbits will also work. What’s most important is that the pineapple is drained well before mixing it with the frosting.
- Lemon Whipped Cream Frosting: Lite whipped topping, sugar-free instant lemon pudding, vanilla extract, and skim milk whip into frosting like a dream. If you prefer lemon cake with vanilla frosting, use sugar-free instant vanilla pudding instead or lemon.
Step-By-Step Instructions


Step 1: Prepare for baking.
Preheat the oven to 350 degrees F. Spray two 9” round cake pans with cooking spray. Dump the can of crushed pineapple into a sieve, and set it aside until the liquid strains out (at least 15 minutes).
Step 2: Mix lemon cake batter.
Mix the cake mix, Greek yogurt, and water in a large bowl. This will only take about a minute, so be careful not to overmix!
Step 3: Bake and cool.
Divide the batter evenly between the cake pans and bake until a toothpick inserted in the middle comes out clean (15-20 minutes). Let the cakes rest in the pans for 5 minutes, then flip onto a wire rack to finish cooling.
Step 4: Make whipped frosting.
Add whipped topping, pudding mix, vanilla, and milk to a medium bowl, and mix until the ingredients are incorporated, and the frosting is creamy. Set aside ¼ cup to use for the filling.
Step 5: Make pineapple filling.
At this point, the crushed pineapple should be strained, so you can start the filling. Add pineapple and the reserved ¼ cup of frosting to a medium bowl and combine.
Step 6: Assemble cake layers and frost.
Place one of the cake rounds on a plate or cake stand. Dump the filling in the center and spread it in an even layer. Place the other cake round on top, forming a lemon cake pineapple frosting sandwich! Finally, apply the remaining frosting, smoothing it in an even layer over all surfaces. Slice, grab a fork, and enjoy!

Expert Tips
- Strain the pineapple well. Strain as much juice from the pineapple as possible. If there’s excess liquid, it will thin the pineapple filling out and ultimately make it soggy.
- Save some pineapple juice. You can use some of the reserved liquid to add a pineapple element to the lemon cakes by substituting water with as much or as little pineapple juice as you like.
- Make frosting with chilled ingredients. For the best results, pull the whipped topping and milk from the fridge immediately before you’re ready to use it.
- Let the cakes cool. I know it’s hard to resist, but you must wait until the cakes are cooled to room temperature before adding the filling and frosting.
Variations
Other fruit fillings – With lemon as the base cake flavor and the frosting flavor, you have lots of room to play with the filling. Instead of canned pineapple, you can make the filling with peaches, pears, cherries, raspberries, and blueberries -the list goes on and on!
Lemon cake with chocolate – If you like lemon with chocolate, make the frosting with chocolate whipped topping instead of regular. Using chocolate pudding mix instead of lemon flavor is also an option.
Coconut – Sprinkle a thin layer of shredded coconut over the frosting. Lemon, pineapple, and coconut are a heavenly trio of tropical flavors.
Storing & Freezing
Storing: Cover the whole cake or single slices tightly with plastic wrap and keep refrigerated in an airtight container for 3-4 days.
Freezing: Freezing is also an option. However, I suggest freezing the cake rounds before frosting. When you’re ready to assemble, thaw in the fridge, and then add the filling and frosting.
Recipe FAQ‘s
Fresh lemon zest! A small amount impacts the bright, lemony flavor in a big way without adding more liquid to the batter.
Sure. You can bake the batter in two 8” square cake pans without adjusting the baking time or the temperature.
Yes. Use a ripe, juicy pineapple for the best flavor. Dice the pineapple tiny and press the pieces into a fine mesh sieve to remove as much moisture as possible.
Oh no! If the cake rounds are set properly, the filling may be causing the problem. It’s important to blot any excess juice from the pineapple. Otherwise, the moisture weighs down the filling and soaks into the cake, making it soggy.
Pineapple is low calorie and a powerhouse of vitamins and minerals like vitamin C and manganese. They are also a fantastic source of antioxidants that may have anti-inflammatory and immune-boosting properties.

We love lemon cakes and this is a wonderful recipe. Will try it for sure.
Beth
Pineapple and lemon are both such great acid flavor pops, they must be a great complement to the sweetness of the cake mix. As we would not likely be able to eat a commercial mix because it would contain gluten, I get to live through your recipes!

Thanks, Beth! I wonder if you could find a gluten-free cake mix that is lemon flavor?
