The Essential Ingredients

Delve into the elements that contribute to the magic of this culinary creation:

  • Milk and Vinegar: This dynamic duo works in tandem to lend the cake a light, airy texture while ensuring it remains moist.
  • Greek Yogurt: Beyond its creaminess, it adds a delightful tang and a generous dose of protein to the mix.
  • Honey: Nature’s liquid gold imparts a gentle sweetness that complements the plums’ natural flavours.
  • Olive Oil: This heart-healthy fat adds a subtle richness to the cake’s profile.
  • Oat Flour: Crafted from blended oats, it brings a nutty essence and caters to those mindful of gluten. You can buy oat flour online or you can make your own by blending oats into a fine powder.
  • Baking Powder and Baking Soda: These leavening agents are the secret behind the cake’s enchanting rise.
  • Plums: While this recipe features plums, feel free to experiment with various stone fruits you have on hand!

Ingredient Substitutions

Milk: I use Cow’s Milk, but you can use any milk you prefer. For dairy-free, I recommend Soy Milk if possible.

Vinegar: White or Apple Cider Vinegar works best, or you can use double the amount of lemon juice.

Greek Yoghurt: Try to use a thick yoghurt so any Greek-style yoghurt or Coconut Yoghurt for dairy-free.

Honey: Whilst this is a honey cake, you may want to make a vegan version, so you can use maple syrup, agave or date syrup.

Olive Oil: You can use any neutral-flavoured oil or melted coconut oil.

Oat Flour: I have not tried this recipe with any other type of flour, but you should be able to use an equal amount of All-Purpose or Wholemeal Flour.

Plums: This is a plum cake, but you can use any type of stone fruit like apricots, peaches or nectarines or even sliced apples.

How to make plum and honey cake

Now, let’s walk through the steps that transform these simple ingredients into a stunning cake that will leave you craving for more. I’ve also got a video below showing you how to make this beauty.

Step 1: Preheat your oven to 180°C (355°F / 160°C fan) and line a 20cm square baking tin with parchment paper.

Step 2: Slice your plums in half, remove the pits, and then slice them into wedges. Arrange them in a captivating pattern at the bottom of your baking tin.

Step 3: In a mixing bowl, whisk together the milk, vinegar, Greek yoghurt, honey, and olive oil until the mixture is smooth and well combined.

Step 4: Add the oat flour, baking powder, and baking soda to the wet mixture. Gently whisk until you have a harmonious batter that’s ready to shine.

Step 5: Pour the batter over the plum slices, ensuring an even distribution.

Step 6: Pop your creation into the preheated oven and let it bake for 22-25 minutes until it turns a glorious golden brown.

Step 7: Once baked to perfection, allow your cake to cool in the tin. Then, with a sense of anticipation, flip it over to reveal the stunning plum mosaic. Peel off the parchment paper, slice into 8 generous pieces, and relish each delightful bite.

Storage Instructions

Refrigeration: Leave the cake to cool completely before placing it in an airtight container. Keep in the fridge for up to 5 days. You can enjoy it cold or heat it in the microwave if you like.

Freezing: For longer-term storage, consider freezing the cake. Wrap individual slices tightly in plastic wrap or aluminium foil, then place them in a resealable freezer-safe bag. The cake can be stored in the freezer for up to 2-3 months.

Thawing: When you’re ready to enjoy your stored cake slices, simply remove them from the refrigerator or freezer. If frozen, let them thaw in the refrigerator or at room temperature. You can even give them a quick warm-up in the microwave if desired.
