Ingredients:

• 1/2 cup unsalted butter
• 1/2 cup coconut oil
• 1/2 cup unsweetened cocoa powder

• 1/4 tsp fine sea salt
• 1/3 cup unsweetened almond butter

• Optional: 1 oz 90% dark chocolate, finely chopped, for extra depth

Instructions:

1. Line an 8×8-inch pan with parchment, leaving overhang for lifting.
2. Melt butter and coconut oil in a saucepan over low heat. Whisk in cocoa, erythritol, salt, and 90% chocolate if using until smooth.
3. Whisk in almond butter and 2 tbsp heavy cream until glossy. Spread half the mixture in the pan.
4. Stir remaining 2 tbsp heavy cream and vanilla into the rest of the mixture to lighten it. Spread gently over the first layer.
