- No powdered sugar needed.
- Silky smooth and pipeable.
- Just four ingredients.
- Bursting with real pineapple flavor.
Ingredient Notes
Pineapple Juice. Go for 100% pure pineapple juice, either bottled or fresh. Avoid syrup from canned fruit as it is too sweet and does not reduce well. You will cook this down into a simple syrup to concentrate the flavor without thinning out the buttercream.
Sugar. Just a tablespoon helps balance the tang of the pineapple and gives the reduction a syrupy consistency. It may seem like a small amount, but do not skip it because it helps the juice reduce more evenly.
Unsalted Butter. Use good quality unsalted butter. It should be soft but not melted. Room temperature is best. You should be able to press your finger into it easily without it sliding around the wrapper. This step gives the buttercream structure and fluff.
Sweetened Condensed Milk. This is the heart of all my condensed milk buttercream recipes. Full fat is essential for a creamy, rich texture. It blends smoothly with butter and adds sweetness without powdered sugar. One standard can, about 395 g or 14 oz, is all you need.
Butter vs Margarine: Which One’s Best for Buttercream?
When making buttercream, real butter always comes out on top. It delivers rich flavor, a creamy texture, and the structure needed for piping. Butter holds its shape well, even when piped into detailed swirls or flowers.
Margarine may be cheaper and easier to find, but it makes a buttercream that is too soft. It can appear greasy and often collapses when piped, especially in warmer conditions. For pineapple condensed milk buttercream that is fluffy, stable, and pipeable, always use unsalted real butter. The difference in texture and finish is significant.
How To Make Pineapple Buttercream
Reduce the pineapple juice. Add juice and sugar to a saucepan. Bring to a boil, then simmer for 5 minutes. Let it cool completely.
Beat the butter. Add softened butter to a mixing bowl. Beat for several minutes until fluffy and pale in color.
Add the condensed milk. Pour in the full can. Beat for another 1-2 minutes until smooth.
Mix in the pineapple reduction. Once cooled, add the reduction to the butter mixture. Mix for 1-2 minutes.
Smooth it out. Mix on low speed for 1-2 more minutes to remove air bubbles. Use a spatula to smooth it if needed.
Fay's Pro Tips for Pineapple Buttercream
- Make sure the pineapple reduction is completely cool.
- Softened butter gives you the fluffiest texture.
- Beat on low speed at the end to remove excess air.
- For extra smooth frosting, massage with a silicone spatula.
Variations and/or Substitutions
Want to switch it up? Try these simple swaps:
- Use mango or passionfruit juice instead of pineapple.
- Add a tiny pinch of salt to cut through the sweetness.
- Mix in a tablespoon of freeze-dried pineapple powder for extra punch.
You can also add this buttercream to my chocolate cake, chocolate cupcakes, vanilla cupcakes or even sandwiched between shortbread cookies.
How To Fix Curdled Buttercream
Curdled buttercream is common when making condensed milk buttercream with a fruit reduction like pineapple. It may look split, lumpy, or grainy at first, but this stage is completely normal.
The solution is simple. Keep mixing on medium high speed for several minutes until the fat and liquid emulsify. The texture will become smooth, fluffy, and silky.
Your pineapple condensed milk buttercream will finish light, stable, and creamy. You have not ruined it, you are just in the middle of the process.

FAQs - Pineapple Buttercream
Nope! Margarine makes the buttercream way too soft and unstable. It won't hold its shape when piped and may look greasy. For the right consistency and flavor, always use real unsalted butter.
If your pineapple buttercream has split, just keep beating it on medium-high speed. The emulsion will re-form as the fat and liquid combine. It may take 3-5 minutes or more. You can also use a spatula to gently fold the mix and remove air bubbles at the end.
Yes, but you need to reduce it into a syrup first. Straight fruit juice adds too much liquid and can upset the emulsion. This pineapple buttercream recipe uses reduced pineapple syrup to create bold flavor and a smooth, stable texture.
Yes. Just make sure it is 100 percent juice with no added sugar or syrup. Avoid juice from canned fruit in syrup because it will not reduce properly and can affect the flavor.
It makes around 4½ cups, which is enough to frost 18-36 cupcakes depending on the size of the swirl, fill and frost a two-layer 6-inch cake, or fill macarons.
It's more stable than traditional powdered sugar frostings, but it's still butter-based. In warm temps, keep your frosted cakes or cupcakes chilled until serving. It pipes beautifully but softens if left out too long.
