This spiced plum
I feel like this cake is double awesome. I mean, a crumble topping is pretty much adding a dessert on top of another dessert. It’s now a cake and fruit crumble in one!
I wrote this post a couple of years back but decided it needed a bit of a revamp. The recipe has changed ever so slightly, and it’s now even better than it was. Fluffier and lighter. I think you’re going to love it.
This cake can be made with any stone fruit,but plums give it a little sour kick that compliments the crumble topping beautifully. I love using red or black plums as they give the best contrast of colour against the soft cake background too.
So now, let’s talk about this plum crumble cake, firstly the ingredients!
Easy Plum Cake Ingredients
The ingredients for this plum cake are listed in the recipe at the bottom of this post but here is a quick run down.
Butter and sugar – There’s butter in this cake for flavour and tenderness. Beat it well with the sugar, so plenty of air gets incorporated.
Eggs – For structure
Vanilla + spices – Vanilla, cinnamon and nutmeg add the flavour to the cake.
Flour + salt – Pretty self explanatory why these two are here.
Baking soda + Baking powder – Both are added for leavening.
Milk + Apple cider vinegar – You can substitute this mixture for buttermilk if you like. The acidity of the vinegar reacts with the baking soda for a light and tender crumb.
Plums– Plums, or stonefruit of your choice. Plums are best in my opinion though. If you do substitute it with another, sweeter stone fruit, I would reduce the sugar in the crumble topping a bit.
The Crumble – The crumble topping has butter, rolled oats, brown sugar, cinnamon and flour.
The Plum Crumble Cake Method
Step 1. Make the crumble topping first by melting the butter, then adding in the remaining crumble ingredients and mixing it together.
Step 2. Mix together the dry ingredients.
Step 3. Beat together the cake sugar and butter until light and creamy. The butter needs to be room temperature (not hotter or colder than that), to allow the optimum amount of air to be incorporated. (Read more about butter temperatures here.)
Step 4. Add the eggs in one at a time, beating well after each addition.
Step 5. Mix together the milk and apple cider vinegar.
Step 6. Add the flour and the milk mixture to the egg mixture, in stages. Alternating between flour and milk. Fold it together gently until it is combined but not over mixed.
Step 7. Spoon the cake batter into a lined tin. Arrange plum halves over the cake batter and top with the crumble topping. Bake until a skewer inserted comes out clean.
Serving the Plum Cake
When removing the cake from the oven, let it cool for 5 minutes before removing from the tin.
This cake can be served warm or at room temperature. Any left over cake can be stored in an airtight container at room temperature for up to three days.
