Soft Custard Butter Cake Bars Recipe

Introduction

This delicious dessert is a rich, soft, and slightly gooey butter cake bar with a delicate custard-like texture inside and a lightly crisp, crackled top. It’s perfect for tea-time, dessert platters, or even special occasions. The combination of butter, sugar, eggs, and flour creates a melt-in-your-mouth experience, while the powdered sugar topping adds a subtle sweetness and elegant finish.

Ingredients

For the Base Layer:

• 1 cup (225g) unsalted butter (softened)
• 1 cup (200g) granulated sugar
• 2 large eggs (room temperature)
• 1 teaspoon vanilla extract
• 1 ½ cups (190g) all-purpose flour
• ½ teaspoon baking powder
• ¼ teaspoon salt

For the Custard Layer:

• 2 large eggs
• 1 cup (200g) sugar
• ½ cup (120ml) milk
• ¼ cup (60g) butter (melted)
• 1 teaspoon vanilla extract
• ½ cup (60g) all-purpose flour

For Topping:

• Powdered sugar (for dusting)

Instructions

Step 1: Prepare the Baking Dish

Preheat your oven to 180°C (350°F).
Grease a 9×9-inch baking pan or line it with parchment paper. This will help you remove the cake easily once it’s baked.

Step 2: Make the Base Layer

In a large mixing bowl, beat the softened butter and sugar together until the mixture becomes light and fluffy. This usually takes about 3–4 minutes using an electric mixer.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this dry mixture into the wet ingredients and mix until a soft dough forms.

Spread this dough evenly into the prepared baking pan. Press it down gently using a spatula or your hands to create an even layer.

Step 3: Prepare the Custard Layer

In another bowl, whisk together eggs and sugar until smooth and slightly pale.

Add milk, melted butter, and vanilla extract, mixing well.

Gradually add the flour and whisk until you get a smooth, slightly runny batter. This layer will create that soft, custard-like texture seen in your image.

Step 4: Assemble

Pour the custard mixture over the base layer evenly. Do not mix the layers—keep them separate.

Gently tap the pan on the counter to remove any air bubbles and help the mixture settle evenly.

Step 5: Bake

Place the pan in the preheated oven and bake for 35–45 minutes.

You’ll notice:

• The top will become golden
• Cracks will form (this is normal and gives the dessert its signature look)
• The center should still be slightly soft but set

Do not overbake, as you want a moist, soft interior.

Step 6: Cooling

Remove from the oven and let it cool completely in the pan.

As it cools:

• The texture will firm up slightly
• The cracks will become more visible
• The custard layer will settle into a creamy consistency

Step 7: Finishing Touch

Once fully cooled, dust the top generously with powdered sugar.

Cut into square pieces, just like shown in your image.

Serving Suggestions

• Serve slightly warm for a softer, melt-in-mouth experience
• Serve chilled for a firmer, custard-like texture
