Tools You’ll Need
Mixing bowl

9-inch round or square cake pan
Parchment paper or non-stick spray
Cooling rack
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Grease your cake pan or line with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together almond flour (or all-purpose flour), baking powder, salt, and sugar substitute.
Step 3: Combine Wet Ingredients
In another bowl, whisk together eggs, melted butter, almond milk, vanilla extract, and almond extract (if using) until smooth.
Step 4: Mix Everything Together
Pour the wet ingredients into the dry ingredients.
Stir until just combined—don’t overmix. The batter should be smooth and thick.
Step 5: Bake the Cake

Step 6: Make the Frosting (Optional)
Whip the heavy cream, powdered sugar substitute, and vanilla extract until soft peaks form.
Spread over the cooled cake or pipe for a decorative finish.
Step 7: Slice & Serve
Slice the cake into squares or wedges. Serve plain or topped with berries, whipped cream, or a dusting of sugar-free powdered sweetener.

Tips for the Best Sugar-Free Vanilla Cake
Use Room Temp Eggs – Helps the batter mix more evenly and gives a fluffier crumb.
Don’t Overbake – Start checking at 25 minutes to keep the cake soft.
Choose the Right Sweetener – Allulose or monk fruit blend works best for a clean taste.
Frost After Cooling – Prevents melting and sliding.
Double the Recipe – Great for a layered birthday cake!

Frequently Asked Questions
1. What’s the best sugar substitute to use?
A granulated blend like erythritol, monk fruit, or allulose works best for texture and flavor.
2. Can I use coconut flour?
Not directly—coconut flour is much more absorbent. You’d need to adjust the liquids and eggs.
3. Is this keto-friendly?
Yes—if using almond flour and a keto-friendly sweetener, it fits well into a low-carb diet.
4. Can I make this dairy-free?
Yes—use coconut oil instead of butter and almond or oat milk.
5. What if I want to make it a layer cake?
Double the ingredients and use two 9-inch pans. Bake for the same time.
