Warm the base: In a small saucepan, combine heavy cream and whole milk. Set over low heat.
You want it warm and steamy, not boiling. Stir occasionally to prevent a skin from forming.
Whisk in flavorings: Add cocoa powder, instant espresso, cinnamon (if using), and the pinch of salt. Whisk until the cocoa fully dissolves and the mixture looks smooth and uniform.
Sweeten: Stir in the sweetened condensed milk.
Keep whisking over low heat for 1–2 minutes until everything is evenly incorporated. Do not simmer or boil.
Finish with extracts: Remove from heat. Whisk in vanilla and almond extract.
Taste and adjust sweetness or cocoa if needed. If it’s too thick, add a splash more milk.
Cool and bottle: Let the creamer cool to room temperature. Pour through a fine-mesh strainer into a clean glass bottle or jar to catch any undissolved bits.
Chill: Refrigerate for at least 2 hours.
It will thicken slightly as it cools. Shake before each use.
Serve: Add 1–2 tablespoons to hot coffee, cold brew, or espresso. Adjust to taste.
