How to Make the Best Keto Chocolate Fudge Loaf Cake
1. Preheat & Prepare the Pan
Preheat your oven to 350°F (175°C).
Line a 9×5-inch loaf pan with parchment paper or lightly grease it to prevent sticking.
2. Mix the Keto Cake Batter
In a large bowl, whisk together:
almond flour
coconut flour
cocoa powder
espresso powder
baking powder
baking soda
salt
In a separate bowl, whisk the eggs, melted butter, erythritol, vanilla extract, and almond milk until smooth.
Combine the dry and wet ingredients, mixing until a thick, rich batter forms.
Fold in sugar-free chocolate chips for extra fudginess.
3. Bake the Keto Chocolate Loaf
Pour the batter into your prepared loaf pan.
Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely—this keeps your Keto Chocolate Fudge Loaf Cake dense and moist.
4. Prepare the Keto Ganache
In a small saucepan over low heat, gently warm the heavy cream until steaming.
Remove from heat and add chocolate chips and butter. Let sit for 1 minute.
Stir until smooth and glossy, then add vanilla extract.
Pour the silky ganache over the cooled cake and spread evenly.
5. Chill & Serve
Refrigerate for 30 minutes to let the ganache fully set.
Slice and enjoy this Keto Chocolate Fudge Loaf Cake chilled or at room temperature.
Optional Keto Add-Ins
