Dimply Plum Cake Is the Last Great Dessert of the Summer

One bowl. Brown sugar cake. Late-summer plums. And, it’s better the day after. Need we say more?

Dimply Plum Cake

End-of-summer scaries hitting hard? Consider this a reminder that the season doesn’t officially wrap until September 21 — PSLs be damned. That’s why we’ll be making Smitten Kitchen’s Dimply Plum Cake on repeat until then.

Not only is the name extremely fun to say, but more importantly, the one-bowl recipe combines a brown sugar cake (made from ingredients you probably have), jammy late-summer plums, orange zest, and a hint of cinnamon. Add powdered sugar and you’ve got a dessert impressive enough for a party, easy enough for a random Tuesday, and virtuous enough for brunch. Plus, on the off chance you have leftovers, they magically taste better the next day.

The Time Commitment: About an hour, but the cake bakes for more than half of that. 

Key Tips: The number of plums you’ll need depends on their size — Deb Perelman (aka Smitten Kitchen) suggests eight small-to-medium ones or five medium-to-large ones. And the recipe works just as well with any stone fruit.  

Other Takes: For more “it's still summer” desserts (think: all the fruity goodness you'll miss come apple season), try…

  • Brown Sugar Peach Crumb Bars. Not to get controversial, but buttery crumb topping > finicky pie crust. Particularly when it’s (probably) your last good peach haul of the year. 

  • Snickerdoodle Strawberry Shortcakes. Sweet cream, strawberries, and the most indulgent cinnamon-sugar toast imaginable join forces for a treat one fan claims “schooled every shortcake I’ve ever had.”

  • Blackberry Nectarine Crisp. Blackberries and nectarines are a match made in fruit heaven — especially under a blanket of brown-sugar oat topping. Serve with vanilla ice cream, and no, it’s not optional.


What’s new in food & home:

🛒 Costco’s latest hit isn’t a bakery item — it’s a $25 plant aisle find that’ll make your friends think you have a florist on retainer. 

👩‍🍳 Apparently, chefs swear by these seven “cheat codes” for making cooking easier and less chaotic. If we could bold, highlight, and underline No. 2, we would.

🌶️ If you’ve cut roughly 1,000 bell peppers in your life and still end up with seeds everywhere (same), this viral hack is about to change your fajita game forever.
