This slow cooker gooey butter cake is warm, messy, and irresistibly rich, with a dense yellow cake base and a creamy, tangy cream cheese layer on top. You’re going to love that it takes just four ingredients and frees up the oven. Serve it straight from the slow cooker for an easy dessert that always disappears fast.
Why You’ll Love It
- Just four ingredients — yellow cake mix, butter, cream cheese, and powdered sugar are all you need.
- No oven needed — the slow cooker handles the baking and keeps the oven free.
- Gooey, buttery texture — a dense cake base meets a creamy, tangy cream cheese topping.
- Easy to serve — scoop it warm right from the slow cooker with no fancy pan or neat slicing required.
Ingredient Notes
Use a regular 15.25-ounce box of yellow cake mix. Nothing fancy is needed here. I usually grab Duncan Hines if it’s on sale, but Betty Crocker works perfectly well too. A butter golden cake mix is wonderful if you want to lean harder into the buttery thing, and French vanilla gives it a slightly different, sweeter flavor. Plain yellow is still my favorite, though.
You’ll need two sticks of unsalted butter, melted and divided. Unsalted is what I use because the cake mix has enough going on already, but if salted butter is all you have, use it. Nobody is going to take a bite and call the authorities.
The cream cheese needs to be softened so it beats up smooth. Leave it out for about an hour, maybe two at most if your kitchen is cool. Don’t leave it sitting around all afternoon while you run errands—I know people do, I have probably done it myself, but cream cheese is not built for a long hot summer day on the counter.
And powdered sugar: three full cups. It looks like a ridiculous amount when you pour it in. It is a ridiculous amount. That’s why the cake is good.
Ingredients
- 1 box (15.25 ounces) yellow cake mix
- 1 cup (2 sticks) unsalted butter, melted and divided
- 2 packages (8 ounces each) cream cheese, softened
- 3 cups powdered sugar
- Nonstick cooking spray or a little extra butter for the slow cooker—technically not part of the four, but let’s not be foolish
Instructions
- Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick cooking spray or a thin smear of butter. If you want easier cleanup, line the bottom and halfway up the sides with parchment paper, pressing it into the corners as best you can. It will not look elegant. It’s going to be covered with cake, so give yourself a break.
- Pour the dry yellow cake mix into a medium bowl and stir in 1/2 cup, or 1 stick, of the melted butter. Mix with a spatula or wooden spoon until there are no dry patches left and it looks like thick, slightly crumbly dough. The first time I made this, I was convinced it needed an egg. It does not. Leave it alone.
- Transfer the cake mixture to the prepared slow cooker and press it firmly into an even layer across the bottom. Clean hands work best, although I usually start with a spoon and then give up halfway through. Make it level-ish. This is the dense buttery layer that holds everything together, more or less.
- In a large bowl, beat the softened cream cheese with a hand mixer on medium speed for 1 to 2 minutes, until smooth and creamy. Scrape down the bowl if you need to. Little cream cheese lumps are not the end of civilization, but smooth is nicer.
- Add the remaining 1/2 cup melted butter to the cream cheese and beat until fully combined. Then add the powdered sugar about 1 cup at a time, starting on low speed unless you enjoy wearing a pale dusty mask of sugar. Once it’s incorporated, increase the speed to medium and beat until the mixture is thick, glossy, and smooth.
- Spread the cream cheese mixture over the cake base, all the way to the edges. It will sit on top in a thick layer and seem like far too much topping. That is correct.
- Cover the slow cooker and cook on LOW for 2 1/2 to 3 1/2 hours. Start checking around the 2 1/2-hour mark, but don’t keep opening the lid every fifteen minutes—slow cookers lose heat, and impatience has ruined more than one dessert in my kitchen. The edges should look set and lightly golden, while the top is puffed and a little crinkly. The center should still jiggle softly when you gently move the insert.
- Turn off the slow cooker and let the cake sit covered for 15 to 20 minutes. It will set up a bit more, though the middle should stay gooey and creamy. If you’re concerned about doneness, the center should reach 160°F on an instant-read thermometer. I don’t usually take its temperature unless somebody has me nervous, which happens more often than I’d like.
- Scoop the warm cake into small bowls or onto dessert plates. For cleaner slices, let it cool longer, lift it out by the parchment, and cut it into squares. Serve it plain or with vanilla ice cream, lightly sweetened whipped cream, or fresh strawberries or blueberries.
Variations
Butter golden cake mix makes the bottom layer extra rich. French vanilla cake mix is also lovely, especially if you’re serving it with berries.
If you want a slightly less intense version—and I hesitate to even say this because the whole point is excess—you can reduce the total butter to 3/4 cup. The cake will be a little less dense and buttery, naturally, but still very good. I made it that way once for a weekday dessert and then proceeded to eat it after 10 p.m. anyway, so apparently moderation is a concept I understand only in theory.
For folks who don’t love the tang of cream cheese, use 1 1/2 packages instead of two and add another 1/2 cup powdered sugar. That does make it a five-ingredient recipe if you’re counting honestly.
One version that did not work for me: chocolate cake mix. It wasn’t horrible, exactly, but it tasted confused. Like a brownie had wandered into the wrong family reunion. Stick with yellow, butter golden, or French vanilla.
If your slow cooker tends to collect a lot of condensation under the lid, you can place a clean kitchen towel under the lid, with the ends safely folded up away from the heating element. It catches drips and helps that top stay crinkly instead of wet-looking.
Storage & Reheating
Once the cake has cooled, cover the slow cooker insert tightly or move the leftovers to an airtight container and refrigerate for up to 4 days. Since there’s cream cheese involved, don’t leave it sitting out all evening. I know it’s tempting when people keep circling back for “one more little bite,” but get it chilled within two hours.
Reheat individual servings in the microwave for 15 to 20 seconds. You want it warm enough to get that gooey center back, not hot enough to turn it into molten lava.
I don’t recommend reheating the entire slow cooker on warm for half the day. Two or three hours after it’s done is plenty if you’re serving it, but after that the texture starts getting a little strange and the dairy has been hanging around too long. Nobody needs that kind of excitement.
Final Notes
This cake has that warm, soft-focus kind of comfort: rich, gooey, buttery, and just a little ridiculous.
Still, a warm scoop of gooey butter cake does something to a room. People stop fussing for a minute. They sit down. They scrape their bowls. Even the ones who said they were “too full for dessert” somehow find space, funny how that works.
Make it when you need an easy sweet thing that feels a little old-fashioned and a little ridiculous. Keep the portions small at first. You can always go back for more… and you probably will.
