Ingredients You’ll Need
- Almond flour
- Granulated erythritol
- Unsweetened cocoa powder
- Baking powder
- Salt
- Unsalted butter, melted
- Large eggs
- Unsweetened almond milk
- Lemon zest
- Fresh lemon juice
- Vanilla extract
Each ingredient plays a crucial role in creating the perfect Fluffy Lemon Custard Cake. Almond flour gives the cake its tender crumb while keeping it low-carb. Granulated erythritol sweetens the deal without the sugar spike. The unsweetened cocoa powder adds a subtle depth, balancing the bright lemon flavor. Baking powder ensures your cake rises to fluffy perfection, and a pinch of salt enhances all the flavors.
Melted unsalted butter adds richness, while large eggs provide structure. Unsweetened almond milk keeps the cake moist, and the lemon zest and juice infuse it with that irresistible citrusy aroma. Finally, a splash of vanilla extract rounds everything out with a hint of warmth. If you’re looking for swaps, you can use coconut milk instead of almond milk for a tropical twist, or try lime juice and zest for a different citrusy kick. Remember, printable measurements are at the end of the article for your convenience.
How to Make Fluffy Lemon Custard Cake
Step 1 – Prep Ingredients
Start by preheating your oven to 350°F (175°C). This is the perfect time to gather your thoughts and ingredients. Grease an 8-inch round cake pan and line it with parchment paper. This little step ensures your cake will slide out effortlessly, leaving no crumb behind.
Step 2 – Begin Cooking
In a large bowl, whisk together the almond flour, erythritol, cocoa powder, baking powder, and salt. This dry mix is the foundation of your cake, so make sure everything is well combined. It’s like building a house—you want a solid base!
Step 3 – Combine Ingredients
In another bowl, mix the melted butter, eggs, almond milk, lemon zest, lemon juice, and vanilla extract. This is where the magic happens. Pour the wet ingredients into the dry ingredients and mix until just combined. Be gentle here; overmixing can lead to a dense cake, and we want it fluffy!
Step 4 – Finish and Serve
Pour the batter into your prepared pan, smoothing the top with a spatula. Pop it in the oven and let it bake for 25-30 minutes. Your kitchen will soon be filled with the most delightful lemony aroma. Once done, let the cake cool in the pan for 10 minutes before transferring it to a wire rack. Serve it chilled or at room temperature, perhaps with a dollop of whipped cream or a handful of fresh berries. It’s a slice of happiness, ready to be enjoyed.
Tips for Perfect Results
For an even lighter texture, try separating the egg whites and yolks. Beat the egg whites until stiff peaks form and gently fold them into the batter. This little trick adds an extra layer of fluffiness. And if you have leftovers (though I doubt you will), store them in an airtight container for up to 3 days. It’s like having a little piece of sunshine waiting for you in the fridge.
