How to Make Keto Butter Cake
Step 1: Preheat and Prep
-
Preheat your oven to 350°F (175°C).
-
Grease an 8-inch round or square baking pan, or line with parchment paper.
Step 2: Mix Dry Ingredients
-
In a large bowl, whisk together almond flour, coconut flour, baking powder, and salt.
Step 3: Mix Wet Ingredients
-
In another bowl, beat the eggs with the melted butter, sweetener, vanilla extract, heavy cream, and apple cider vinegar until well combined.
Step 4: Combine and Stir
-
Gradually add the dry ingredients into the wet mixture.
-
Stir until a thick batter forms — it should be smooth and scoopable, not pourable.
Step 5: Bake
-
Spread the batter evenly into the prepared baking pan.
-
Bake for 30–35 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
Step 6: Cool and Serve
-
Allow the cake to cool in the pan for at least 15 minutes.
-
Slice and serve plain or with whipped cream or berries.
Notes
-
Sweetener: Erythritol and monk fruit blends work best. Avoid liquid sweeteners as they may change the texture.
-
Flavor Add-Ins: Add lemon zest, almond extract, or cinnamon for extra flavor.
-
Storage: Store in the fridge in an airtight container for up to 5 days. Can also be frozen for up to 2 months.
-
Serving Tip: Warm individual slices for 10 seconds in the microwave to bring back that freshly-baked softness.
FAQs
Q: Can I use only almond flour?
A: You can, but the combination with coconut flour improves texture and reduces density. If using only almond flour, increase by 1/2 cup and reduce eggs slightly.
Q: Is this cake diabetic-friendly?
A: It’s low in net carbs and uses sugar alternatives, so it may be suitable for diabetics. Still, check with your healthcare provider if unsure.
Q: Can I use butter substitutes?
A: For dairy-free, use ghee or coconut oil — but note it will alter the flavor slightly.
Q: Why apple cider vinegar?
A: It reacts with the baking powder to create lift in the absence of gluten.
