Moist Custard Cake Ingredients
• For the Batter
- Self Raising Flour – Provides structure and rise; substitute with all-purpose flour plus baking powder for a similar effect.
- Butter (Room Temperature) – Adds richness and moisture; can replace with margarine or vegetable oil in a pinch.
- Vanilla Extract – Imparts flavor and aroma; use almond extract for a delightful variation in taste.
- Caster Sugar – Sweetens the cake for a fine texture; granulated sugar can be used, but will affect the cake’s texture slightly.
- Eggs – Binds the mixture and adds moisture; substitute with flax eggs for a vegan version.
- Custard Powder – Provides flavor and creaminess, crucial for this Moist Custard Cake; instant pudding mix can serve as a substitute but may alter the taste slightly.

Step‑by‑Step Instructions for Moist Custard Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). This ensures that when your delightful Moist Custard Cake batter is ready, the oven will be at the perfect temperature to create that moist, tender crumb. Use the convection setting if available for an even bake, and be sure to prepare your cake tin by greasing it with butter or a non-stick spray.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine 1 ½ cups of self-raising flour, 1 cup of custard powder, and 1 cup of caster sugar. Whisk them together thoroughly until evenly mixed, ensuring there are no lumps in the flour or custard powder. This step is crucial for achieving the fluffy texture of the Moist Custard Cake, so take a moment to really blend these dry ingredients for consistency.
Step 3: Cream Butter and Eggs
In another bowl, beat ½ cup of room temperature butter and 3 large eggs together until the mixture is light and creamy, which should take about 3-4 minutes using an electric mixer on medium speed. This incorporates air into the batter, creating a light texture, essential for your Moist Custard Cake. You’ll know it’s ready when the mixture is pale and fluffy.
Step 4: Combine Wet and Dry Ingredients
Gradually add the flour mixture to the creamed butter and eggs while also pouring in 1 cup of milk and 1 tsp of vanilla extract. Mix on low speed just until the ingredients are combined. Be careful not to over-mix; a few lumps are fine. The goal is a smooth, slightly thick batter that will contribute to the cake’s moistness.
Step 5: Pour into the Cake Tin
Carefully pour the cake batter into your greased cake tin, using a spatula to ensure it spreads evenly. Tap the tin gently on the counter to release any air bubbles and help the batter level out. This simple step aids in achieving that lovely, even rise in your Moist Custard Cake, making it look as good as it tastes.
Step 6: Bake the Cake
Place the cake tin in the preheated oven and let it bake for 30-35 minutes. You’ll want to keep an eye out for a golden-brown top and the cake pulling away slightly from the edges. To check for doneness, insert a skewer into the center; if it comes out clean, your Moist Custard Cake is ready to be taken out of the oven.
Step 7: Cool the Cake
Once baked, allow the cake to cool in the tin for about 10-15 minutes. This helps it firm up slightly, making it easier to transfer. Then, gently run a knife around the edges before inverting it onto a wire rack to cool completely. Cooling properly is key to retaining the cake’s moisture and flavors, making each slice a delightful treat.

Moist Custard Cake Recipe FAQs
What type of flour should I use for the Moist Custard Cake?
I recommend using self-raising flour for a light, fluffy texture. If you don’t have it on hand, you can substitute with all-purpose flour by adding 1 ½ teaspoons of baking powder for every cup of flour. This will provide the necessary lift and help your cake rise beautifully!
How should I store the Moist Custard Cake?
For the best taste and texture, store your Moist Custard Cake in an airtight container at room temperature for up to 3 days. If you’d prefer to keep it for longer, you can refrigerate it for up to a week in a sealed container, although this may slightly affect its moistness.
Can I freeze Moist Custard Cake?
Absolutely! To freeze, wrap your cooled cake tightly in plastic wrap, then in aluminum foil, and place it in the freezer. It can be stored this way for up to 1 month. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight. For a quick refresh, warm individual slices in the microwave for 10-15 seconds!
What if my cake doesn’t rise properly?
If your Moist Custard Cake doesn’t rise, check if you used fresh self-raising flour or baking powder, as expired leavening agents can cause this issue. Ensure proper mixing techniques—creaming butter and sugar until light and fluffy is key. Also, remember that the oven should be preheated properly, as baking in an oven that isn’t hot enough can lead to a dense cake.
Is this recipe suitable for those with dietary restrictions?
Yes! This recipe can be easily adjusted for certain dietary preferences. To make a vegan version, substitute eggs with flax eggs (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water per egg) and use plant-based milk. Always double-check ingredients like custard powder for any allergens, and feel free to ask about substitutions if you’re unsure!
