Ingredients for Microwave Apple Cake Recipe Uk

Pantry staples plus a couple fresh apples. Simple, quick, and impossibly moist every time.

The apples are key here. Granny Smith gives that tart contrast to the sweet batter, but any firm apple works. I grab mine from Tesco or Sainsbury’s—look for unbruised fruit with a bit of heft. The flour doesn’t need to be anything fancy; plain flour from the baking aisle is perfect (just check it’s not self-raising). For the oil, sunflower or rapeseed are neutral and keep the crumb tender without any weird aftertaste.

No Granny Smith? Braeburn or Cox apples work just as well. Swap raisins for sultanas or chopped dates if that’s what’s in the cupboard. Out of walnuts? Pecans or almonds add the same crunch. If you’ve only got self-raising flour, skip the baking powder—it already has leavening. The brown sugar can be light or dark (dark gives a deeper molasses note).

This cake keeps beautifully. Store in an airtight container at room temperature for 3-4 days—if it lasts that long. The microwave method means it stays moist, so no need to refrigerate. Freezes for up to 3 months (slice before freezing for easy portions).

Step-by-Step Instructions for Microwave Apple Cake

This foolproof method delivers a moist, spiced cake with minimal effort and maximum flavor.

Step 1: Prepare the Apples and Wet Ingredients

Peel and finely dice the 2 whole Granny Smith Apples into small, uniform pieces—about ¼-inch cubes. Toss them immediately with the 1.5 tsp Ground Cinnamon to prevent browning and infuse flavor. This step ensures every bite has that warm spice.

In a large microwave-safe bowl, whisk together the 0.5 cup Vegetable Oil, 0.75 cup Granulated Sugar, and 0.5 cup Light Brown Sugar until smooth. Add the 2 whole Large Eggs and 1 tsp Vanilla Extract, then beat vigorously for 1 minute until pale and slightly thickened. The mixture should look creamy and well-emulsified.

Step 2: Combine Dry Ingredients and Fold Everything Together

Sift the 1.5 cups All-Purpose Flour and 1.5 tsp Baking Powder directly over the wet ingredients. Add the 0.5 tsp Salt. Gently fold with a spatula until just combined—overmixing will make the cake dense.

Now, fold in the diced apples, 0.5 cup Chopped Walnuts, and 0.5 cup Raisins (drained if soaked). The batter will be thick and studded with chunks. Here’s the thing—if it seems too stiff, add a splash of the raisin-soaking water to loosen it slightly.

Step 3: Microwave in Stages for Even Cooking

Smooth the batter into the same bowl, creating an even layer. Microwave on high power for 5 minutes. You’ll notice the edges start to set and pull away from the bowl—this is normal.

Rotate the bowl 180 degrees and microwave for another 4-5 minutes. The cake is done when the center springs back when lightly pressed and a toothpick inserted comes out with just a few moist crumbs. If it’s still wet, microwave in 1-minute bursts until set.

Step 4: Rest and Serve Warm

Let the cake rest in the microwave for 2 minutes—this allows it to finish setting and makes it easier to remove. Run a knife around the edges, then invert onto a serving plate. The top should be domed with a crackly, caramelized crust from the sugars.

Serve warm, sliced into wedges. Each piece will be packed with tender apple, crunchy walnuts, and plump raisins, all enveloped in a moist, cinnamon-spiced crumb. For extra decadence, dust with powdered sugar or serve with a dollop of whipped cream.

Serving Suggestions for This Dish

Warm Serving Ideas

Serve this straight from the microwave while it’s still warm—the aroma of cinnamon and apples will fill your kitchen. I love slicing it into wedges and serving in the same bowl for a rustic presentation. The warm, moist crumb is at its best right away. 💛

Creamy Toppings

A dollop of clotted cream or vanilla custard adds a luxurious touch that’s very British. For a lighter option, Greek yogurt with a drizzle of honey balances the sweetness. These toppings enhance the cake’s texture without overpowering it.

Ice Cream Pairing

Vanilla ice cream is a classic choice—let it melt slightly over the warm cake. I prefer Mackie’s of Scotland vanilla for its rich, creamy texture. The contrast of hot and cold makes each bite more enjoyable.

Fruit Accompaniments

Stewed apples or a simple apple compote can be spooned over the top for extra fruitiness. Lightly poach 1 diced apple in 2 tbsp brown sugar and 1 tsp cinnamon for 5 minutes in the microwave for a quick compote.

Beverage Pairings

A hot cup of Earl Grey tea complements the spiced apple flavors beautifully. For coffee lovers, a flat white or latte works wonders. The warmth of the drink pairs perfectly with the cake’s cozy flavors. ✨

Simple Garnishes

Sprinkle with powdered sugar or add a few toasted walnuts on top for crunch. A dusting of ground cinnamon enhances the visual appeal and adds a final aromatic touch.
