🍰 How to Make Custard Cake Bars (Step-by-Step)

Below is your complete, clearly numbered instruction list.

— Instructions —

Preheat your oven to 350°F (175°C). Line a rectangular cake pan with parchment paper.
In a mixing bowl, whisk flour, baking powder, and salt.
In another bowl, beat eggs and sugar until pale and fluffy.
Add milk, oil, and vanilla to the egg mixture and mix gently.
Fold the dry ingredients into the wet mixture until smooth.
Pour the batter into the prepared pan and bake for 18–20 minutes. Let cool completely.
While cake cools, prepare the custard: heat milk and sugar in a pot until warm.
In a small bowl, whisk egg yolks and cornstarch until smooth.
Slowly add some warm milk to the yolks (tempering them), then pour the mixture back into the pot.
Cook on low heat, whisking until thick and creamy.
Remove from heat and stir in butter and vanilla. Let custard cool slightly.
Prepare the cream layer by whipping heavy cream, powdered sugar, and vanilla until stiff.
Slice the cake horizontally into two even halves.
Spread the cream layer on the bottom half.
Pour the custard layer over the cream.
Place the second cake layer on top, gently pressing.
Refrigerate for at least 2 hours to set.
Dust with powdered sugar before slicing and serving.

💡 Expert Tips for Perfect Custard Cake Bars

✔ Don’t rush the custard.
Slow heat prevents curdling and produces the silkiest texture.

✔ Let the cake cool fully.
Warm cake can melt or deflate the cream layer.

✔ Chill at least 2 hours.
The longer it chills, the firmer and cleaner your slices will be.

✔ Use a sharp knife to cut.
Wipe between cuts for perfect bakery-style edges.
