Costa Millionaires Mocha, 6 Sachets 138g
Read it as a liquid millionaires shortbread, not a coffee: a triple-cocoa, caramel-and-vanilla dessert in a sachet where the actual coffee sits well back, three out of five at most. That is the point, not a flaw, but if you want a proper coffee hit this is the wrong sachet. As an indulgent, frothy chocolate-caramel treat made in seconds with no machine it genuinely delivers, and at a fraction of the cafe price. A cold-night reward or pudding substitute; sweet, rich, and unapologetically not a serious coffee.
Costa Millionaires Mocha, in brief.
Costa Millionaires Mocha, 6 Sachets 138g is the indulgent caramel chocolate and Costa coffee latte mix in single serve sachet format, built for cafe style mocha at home with no machine. The full picture of how this 6-sachet carton performs, what each cup actually costs per serve compared to the cafe drink, and why this is the variant Costa drinkers reach for first as the dessert treat cup.
The blend is a powdered Costa coffee + caramel + chocolate latte mix built on Costa Mocha Italia signature coffee for the proper coffee base, real cocoa for the chocolate depth, caramel flavouring for the dessert leaning sweetness, sugar, and skimmed milk powder for cafe style cup body. One sachet (23g) into a 250ml mug, top with 200ml hot water, stir for ten seconds, and you get the cafe grade mocha in 30 seconds.
Texture is rich and indulgent, with the caramel flavour, real cocoa and milk powder combining into the thickest cup in the Costa at home range. The cup reads as a dessert drink rather than a daily morning coffee, with proper chocolate depth, caramel sweet finish, and the Costa Mocha Italia coffee base providing the genuine espresso bite underneath. Suitable for vegetarians, contains dairy from the milk powder.
Costa Millionaires Mocha exists as a functional tool for the modern coffee enthusiast who demands the chocolate champion of the Costa at home range. It is specifically designed for those who crave a decadent dessert like coffee experience without the requirement for a barista. Unlike standard instant mixes, this mocha is structured to deliver a complex and luxurious finish through a triple chocolate framework. It is the ultimate treat yourself sachet, perfect for substituting a dessert or warming up on a cold night in 2026.
By marrying high quality roasted Arabica and Robusta beans with a rich caramel and vanilla profile, Costa has created a mocha coffee that feels like a professional extraction. The 29 percent cocoa system provides a robust backbone that stands up to the silky dairy powders. Whether enjoyed as a mid afternoon energy boost or a decadent evening reward, these sachets offer a consistent sensory excellence that honours the coffeehouse heritage.

The Story Behind the Costa
Packaging: Follow the current UK pack and local-authority guidance; components can require different disposal routes.
The Planet Friendly Promise
Costa is a leader in sustainable coffee production ensuring that every component of this product respects the environment and the livelihoods of growers.
-

-
Waste Reduction Strategy: The portion controlled sachet format is specifically designed to minimise product waste while maintaining absolute freshness.
The Barista Home Serve Brewing Guide
-
Measure: Empty one 23g sachet into a favourite pre warmed mug.
-
Water: Use hot but not boiling water. Pour in 200ml of water directly over the powder.
-
Combine: Stir vigorously to ensure all the cocoa and coffee powders dissolve and activate the proteins.
-
Technical Double Stir: Wait for 20 to 30 seconds after the first mix then stir again. This allows the stabilisers to hydrate fully and reach the optimal froth density for a much thicker and more persistent mocha head.
The Indulgent Paste Hack
-
The Prep: Add a small amount of hot milk instead of water to the sachet powder first to create a thick and glossy chocolate paste.
-
The Serve: Top with the remaining hot water or milk. This ensures a lump free and even more decadent mocha experience in 2026.
-
The Finish: For a true millionaire style experience top with a dusting of chocolate shavings or a drizzle of caramel sauce to amplify the aromatic profile.
