The first time I baked this Lemon Custard Cake, I was chasing a break from the usual rushed dinners at our house. School days were packed with pick-ups, homework battles, and last-minute snack demands. I needed a simple homemade lemon dessert that would bring some sunshine and calm to our chaotic kitchen nights.
I found the recipe tucked in an old cookbook, its promise of a cream custard cake filled with bright lemony flavor sounded like a soft hug for both kids and adults. When I pulled that Lemon Custard Cake out of the oven, the scent alone lifted everyone’s spirits. My kids’ wide eyes and Daddy’s contented sigh made it clear this wasn’t just any lemon cake — it was a comfort win.
Every forkful felt like a little family moment, the tang of lemon balanced perfectly with the smooth custard filling. This citrus dessert quickly became a quiet staple in our home, a simple reminder that good food doesn’t need to be complicated or time-consuming.
As I learned to make this Lemon Custard Cake, I discovered how adjusting sugar levels and timing the custard just right made a big difference for my family’s taste buds. If you’re a fellow comfort seeker, juggling the cozy chaos of family life, this cake promises a soothing, doable dessert to add to your rotation. Let’s walk through why this Lemon Custard Cake feels like a little celebration for everyday.
Ingredients You’ll Need:

1 ¾ cups all-purpose flour – The base for your cake, soft and reliable.
2 teaspoons baking powder – Makes your lemon cake rise just right.
½ teaspoon salt – Balances the sweetness in the lemon custard cake.
¾ cup sugar – You can cut back a bit if your family prefers less sweet.
2 large eggs – These bind everything, giving body to the cream custard cake.
½ cup unsalted butter, melted – Adds richness and moisture. If you’re looking for a comfort hack, try using coconut oil for a subtle twist.
½ cup whole milk – Helps keep the cake tender.
Zest and juice of 2 lemons – The star of your homemade lemon dessert, packed with fresh citrusy brightness.
For the custard filling:
- 1 cup milk – Warm and soothing for the custard filling.
- 3 large egg yolks – Gives your custard filling that creamy texture.
- ⅓ cup sugar
- 3 tablespoons cornstarch – Thickens the custard filling perfectly.
- 2 tablespoons butter – Adds smoothness.
- The juice of 1 lemon – More citrus punch in the custard filling.
No worries if you don’t have fresh lemons; bottled lemon juice works fine in a pinch, although fresh zest truly makes your lemon custard cake sing! These ingredients are staples you can find during your regular grocery hauls without special trips.
Shopping tip: grab organic lemons if possible for that intense citrus flavor. And here’s a comfort hack—prepare the custard filling while the cake base bakes to save time. My family gets extra joy when I add a little lemon zest on top for that burst of color and flavor.
This simple ingredient list is proof that making a luscious lemon custard cake doesn’t have to mean complicated shopping or expensive specialty items. Affordable and accessible—that’s the MommiesMore comfort promise!
Let’s Make it Happen!
1. Preheat your oven to 350°F and prepare your pan. I line an 8×8 inch baking pan with parchment paper to make cleanup a breeze. Trust me, moms, this convenience is a lifesaver!
2. Mix dry ingredients. Combine flour, baking powder, and salt in a bowl. Set aside.
3. Prepare your wet mix. In a large bowl, beat sugar and eggs until smooth. Add melted butter and milk slowly. Whisk in the lemon zest and lemon juice. You’ll already smell that lovely citrus scent filling your kitchen, a small comfort in the messy day.
4. Combine wet and dry. Add the dry ingredients gently and mix until combined. Don’t overmix – that keeps your lemon cake tender.
5. Pour batter into the pan and bake for 20-25 minutes. While your Lemon Custard Cake is baking, it’s the perfect moment to prep tomorrow’s school snacks or enjoy a quick breather.
6. Make the custard filling. Warm the milk slowly in a pan. In a bowl, whisk egg yolks with sugar and cornstarch. Slowly add warm milk to the yolks, whisking as you go. Return mixture to heat, stirring until thickened. Remove from heat and stir in butter and lemon juice. The custard filling should smell luscious and creamy.
7. As soon as the cake is out of the oven, poke holes all over it with a skewer or fork. Pour the custard filling evenly over the cake. The custard will seep into the holes, creating a soft, moist texture that makes this lemon custard cake so comforting.
8. Let it cool completely, then refrigerate for at least 2 hours. This wait time can feel long, but the results are worth the patience. Your family will thank you when they taste this smooth cream custard cake.
9. Slice and serve with a smile. Don’t worry if your Lemon Custard Cake looks less perfect than a bakery one – it’s made with love and that counts the most!
Over time, I learned letting this lemon custard cake chill overnight makes it even better. It’s become a beloved kitchen ritual and an easy dinnertime win for our busy household.
