Iced Oat Milk Mocha (Espresso + Dark Cocoa)
Davis Whitehead·3 min·Makes 1 iced mochaA bold, coffee-forward iced mocha built from a smooth dark-cocoa paste, then loosened with espresso and oat milk over ice. It’s lightly sweet with a clean chocolate finish—more “dark chocolate” than milkshake. The key is blooming the cocoa with boiling water first so it dissolves fully and doesn’t taste gritty. Great as a fast morning drink when you want café vibes at home with minimal equipment.

Ingredients
- •45 g espresso (about 1 1/2 oz)
- •6 g dark cocoa/cacao powder (about 1 Tbsp)
- •15 g boiling water (about 1 Tbsp)
- •6 g honey (about 1 tsp)
- •125 g barista oat milk (about 125 ml / 1/2 cup)
- •120–180 g ice (about 1–1 1/2 cups), to taste
- •Pinch of fine salt (optional)
Instructions
Build the mocha base
In a sturdy glass or mug, whisk 6 g cocoa powder with 15 g boiling water until it turns into a smooth, glossy paste with no dry pockets.
Whisk in 6 g honey (and a pinch of salt, if using) until fully dissolved.
Pour in 45 g espresso and stir well; the mixture should look like thin hot chocolate and smell deeply cocoa-forward.
Chill and serve
Add 120–180 g ice to your serving glass.
Pour the mocha base over the ice, then add 125 g oat milk. Stir 10–15 seconds until evenly colored and well chilled.
Taste: if it finishes bitter or sharply dark, add another 2–4 g honey and stir; the bitterness should round out and the aroma should read more like chocolate than roast.
Tip: If you see specks of cocoa floating, you didn’t whisk long enough in Step 1—make the paste perfectly smooth before adding espresso.
Notes
Your first version (6 g cocoa, 15 g boiling water, 6 g honey, 45 g espresso, 125 g oat milk, ice) tasted good but came out a little bitter.
Next time: try 8 g cocoa + 10–12 g honey. More cocoa increases chocolate body and can read less “roasty” when you also increase sweetness; the extra honey helps balance bitterness.
If it’s still bitter with 8 g cocoa: keep cocoa at 8 g and push honey to 12–14 g, or add a slightly bigger pinch of salt.
If it’s too thick with 8 g cocoa: add 10–20 g extra oat milk or a small splash of water.
