Plum Butter

This Plum Butter recipe, known as Pflaumenmus in Germany and Powidl in Austria, is made in the slow cooker for an incredibly deep, rich, caramelized flavor. It’s easy to make and if canned properly will keep for up to a year. It’s delicious on bread, muffins, scones, waffles, pancakes, added to cakes and pastries, and even served with grilled meats and seafood!

Plum Butter brings back memories of the time I spent with my Oma and Opa growing up in southern Germany. There it’s called Pflaumenmus and you can readily find it in any grocery store next to the jams and marmalades. My Oma used to make Kartoffelpuffer (potato pancakes) and we would eat them with apple sauce (Apfelmus) or Pflaumenmus. She would also use it as a filling for one of my favorite Swabian dishes, Dampfnudeln: Sweet yeast dumplings filled with fruit and served drizzled with brown butter and hot vanilla custard. I would imagine plum butter or something similar is made wherever plums grow, but for me it will always be associated with Germany.
This version is for the slow cooker but in Germany plum butter is most commonly made by baking it in the oven in a heavy pot with lid closed, usually around 350 F for 2-3 hours. The oven method produces a little different texture, a slightly more jam-like consistency versus the consistency of apple butter. I’ve made it both ways and both are excellent. For the sake of convenience I usually use the slow cooker. I also like the deeper caramelization that takes place through the lengthy slow cooking process.

Tips for Making Plum Butter
The longer you cook the plum butter the deeper the flavor will be; it will develop a rich caramelized flavor over time. I’ll often cook it for 20 hours on LOW (yes, 20), then remove the lid and puree the plum with an immersion blender, and leave the lid open as it simmers for another 4-5 hours until quite a bit of the liquid has evaporated and the plum butter is thickened.
Alternatively, you can cook it on HIGH for about 4 hours, blend it, and then leave the lid open (still on HIGH) for another couple of hours until thickened. The LOW and HIGH routes both produce excellent results.
A note on sugar: The plums themselves can be safely canned without the addition of any sugar (most fruits, including plums have enough acidity to be safely canned without anything added to them), so that means you can freely use as much or as little sugar as you prefer.
Really, there are no rules here and no matter which route you take – slow cooker on low vs. slow cooker on high vs. oven vs. sugar or no sugar – it’s going to taste delicious!

Italian plums (aka, European plums) are used for plum butter in Germany. Unlike all other varieties of plums, Italian plums are especially suitable for cooking and develop a nice, complex flavor in the process. Their season is very short, usually September through early October, so take advantage of them while you can.
We’re very fortunate to have 3 Italian plum trees and I’ve been working up a storm in our kitchen using the plums every which way (more plum recipes to come!). Making plum butter is a great way to preserve them so you can enjoy their flavor throughout the year.


Plum Butter Recipe
Let’s get started!
Slice the plums in half and remove the pits. Place the plums in the slow cooker.

Stir in the sugar, cinnamon and cloves.

Cook either on LOW for at least 10 hours or on HIGH for at least 4 hours until the plums are very soft.

Use an immersion blender (or transfer to a blender, puree and return to the slow cooker) to puree the plum butter until smooth. If you prefer it a little chunky, blend until the desired texture is achieved.

Continue to simmer the plum butter, this time with the lid opened, until the plum butter is reduced in volume to a spreadable texture, approximately 5-6 more hours on LOW or 3-4 hours on HIGH.
The longer you simmer the plum butter the more deeply caramelized it will be. If you’re going to simmer it for a much longer time, I recommend doing so on LOW to prevent burning.
Once it’s reached the desired consistency, taste it. You can add more sugar at this point if you prefer and let it simmer until the sugar is dissolved.

Enjoy!
Spread this on toast, bagels, muffins or add it to a savory glaze for chicken or incorporated in your favorite BBQ sauce. Or serve it the traditional Austrian way with homemade Germknödel!

Well, it 2018, January, Hobart, making this wonderful plum butter at this very moment. I have always made pear butter ( great mixed with yoghurt for babies) thanks for the recipe
I hail from the Rhine Palatinate and have always been mad about this stuff. Unfortunately, I don’t have a recipe. I only remember that a relative once said you need to add vinegar to it. All plum butters I have tried are too sweet. Maybe they also did not add sugar. Can you or anyone else advise me? Thanks in advance for any help.

Could this be frozen instead of canned?
Hi Lynn, yes it can be frozen.
I’m so glad I found your plum butter recipe when searching for “what the hell do I do with a tree full of plums”. Your recipe was easy to follow and the plum butter (pflaumenmus) was superb! YUMMY! I processed most of the recipe for gifts at the end of the year.
Thanks again!
Lol, Marcia, I’m glad you found a delicious use for all those plum!
Thank you so much for sharing this recipe!!! I have a tree of round purple plums – grown up wild from the rootstock of an old Italian prune plum tree that died – so the variety is whatever the prune plum was grafted onto. I’m just processing my first batch of plum butter right now, made with no sugar at all, I just added cinnamon and cardamom. So, so delicious! And the crockpot method is brilliant. Thanks again!
Wonderful, Glenda! Cardamom is a wonderful touch, I’ve been making peach butter using cardamom as well. Enjoy!
How about the recipe for dampfnudeln? I had it at a street fair in Zurich and loved it 😀
I know, Cindy, they’re one of my favorite things ever! Yes, I still need to get around to posting that :)
I am making this now, but on the stove. I used to have wild plum trees and made this every season, but without the spice. I added that this time.
Wonderful, Elaine! In addition to the slow cooker and stove top, I’ve also baked it in the oven (the method many Germans use) and it turns out fabulous and with a little different consistency.
Dampfnudeln mit Pflaumenmus – so delicious! I’ve never made Pflaumenmus in the oven, I have to give it a try. Unfortunately I don’t have a slow cooker…
