How to Use Pump Street Baking Chocolate for Perfect Brownies

There’s brownie, and then there’s a brownie made with single-origin, bean-to-bar chocolate. The difference is night and day. When you use Pump Street baking chocolate, you’re not just adding cocoa solids—you’re layering in the nuanced fruit, spice, and earth notes that come from carefully fermented and roasted cacao beans. Whether you prefer a deep, dark 85% bar or a more balanced 66%, the right chocolate transforms a humble tray bake into a bakery-worthy indulgence.

In this guide, we’ll walk you through everything you need to know: how to select the best Pump Street chocolate for brownies, how to melt it without seizing, and how to adjust your recipe for different cocoa percentages. We’ll also share a simple, foolproof brownie method that highlights the chocolate’s flavour—no fancy equipment required. Ready to bake the best brownies of your life? Let’s dive in.

Why Pump Street Baking Chocolate Makes Better Brownies

Most supermarket chocolate is mass-produced and lacks complexity. Pump Street, on the other hand, sources single-origin beans and roasts them in small batches, preserving the unique flavour profile of each origin. Their baking chocolate range includes bars like Double Sourdough & Sea Salt 66% and Madagascar - Ambanja 72%, both of which melt beautifully and bring distinct tasting notes to your brownies. The Double Sourdough & Sea Salt 66% adds a subtle tang and a touch of salt that cuts through the sweetness, while the Madagascar - Ambanja 72% offers bright berry and citrus undertones that complement dark chocolate brownies perfectly.

Another standout is the Drinking Chocolate - Ecuador 85%, which, despite its name, can be used as a baking chocolate. Its high cocoa content (85%) delivers an intense, fudgy result with less sugar, letting the cacao’s natural flavour shine. For brownies, you want a chocolate that melts smoothly and has a high cocoa butter content—Pump Street’s bars typically have a high percentage of cocoa butter, which helps create that signature fudgy, melt-in-your-mouth texture.

• Use a chocolate with at least 66% cocoa for balanced sweetness and deep flavour.
• Single-origin bars like Madagascar 72% add unique fruit notes to your brownies.
• Avoid chocolate with added vegetable oils; pure cocoa butter yields a better texture.

Choosing the Right Cocoa Percentage for Your Brownie

The cocoa percentage in your chocolate directly affects the brownie’s sweetness, texture, and intensity. For a classic fudgy brownie that’s not too bitter, a 66% to 72% bar is ideal. The Double Sourdough & Sea Salt 66% is a fantastic all-rounder: it’s dark enough to taste rich, but the sourdough fermentation adds a mild tang that balances the sugar. If you prefer a more intense, almost bittersweet brownie, go for the Ecuador 85%—just be sure to increase the sugar in your recipe slightly to compensate for the lower sweetness.

For those who love a milkier brownie with a softer crumb, you can blend a dark bar with a milk chocolate like Madagascar Milk 58%. However, for the best results, we recommend sticking with a single dark chocolate and adjusting the sugar to your taste. Remember: the higher the cocoa percentage, the more cocoa butter (and less sugar) in the bar. This means your brownies will be richer and more tender, but also more prone to overbaking if you’re not careful. Always use an oven thermometer and check for doneness a few minutes early.

• 66% cocoa: balanced, fudgy, crowd-pleasing.
• 72% cocoa: intense, with fruity or floral notes.
• 85% cocoa: deeply dark, best for dark chocolate lovers—add extra sugar.

How to Melt Pump Street Chocolate Without Seizing

Melting chocolate seems simple, but it’s easy to ruin a batch if water gets in. Pump Street’s craft chocolate has a high cocoa butter content, which makes it smooth when melted but also sensitive to moisture. Always chop your chocolate into small, even pieces—about the size of a pea—so it melts uniformly. Use a double boiler or a heatproof bowl set over a pan of simmering water (make sure the bowl doesn’t touch the water). Stir gently with a rubber spatula until about two-thirds of the chocolate is melted, then remove from heat and stir until fully smooth.

Alternatively, you can melt chocolate in the microwave in 20-second bursts at 50% power, stirring between each burst. This method is faster but requires careful attention to avoid overheating. If your chocolate does seize (turn grainy or stiff), you can sometimes rescue it by adding a teaspoon of warm water or milk and stirring vigorously—but prevention is best. For brownies, you’ll typically melt the chocolate with butter, which adds fat and helps prevent seizing. Just make sure your butter is at room temperature and cut into small cubes before adding it to the warm chocolate.

• Chop chocolate evenly for consistent melting.
• Never let water or steam contact the chocolate.
• Melt with butter for extra smoothness and flavour.

A Simple Fudgy Brownie Recipe Using Pump Street Chocolate

This recipe is designed to highlight the flavour of your chosen Pump Street bar. It yields a dense, fudgy brownie with a crackly top. You’ll need: 200g Pump Street baking chocolate (chopped), 150g unsalted butter, 200g caster sugar, 2 large eggs, 1 tsp vanilla extract, 80g plain flour, 30g cocoa powder, and a pinch of salt. Preheat your oven to 170°C (160°C fan) and line a 20cm square tin with baking paper. Melt the chocolate and butter together using the double boiler method, then let it cool slightly.

In a separate bowl, whisk the sugar, eggs, and vanilla until thick and pale—about 3 minutes. Fold the melted chocolate mixture into the egg mixture until just combined. Sift the flour, cocoa powder, and salt over the batter and fold gently until no streaks remain. Pour into the prepared tin and bake for 22–25 minutes. The brownies are done when the top is set and a toothpick inserted into the centre comes out with a few moist crumbs. Let them cool completely in the tin before cutting. For an extra touch, sprinkle a little flaky sea salt on top before baking—it pairs beautifully with the Double Sourdough & Sea Salt 66%.

• Use room-temperature eggs for better emulsion.
• Do not overmix the batter after adding flour—this keeps brownies tender.
• Cool completely for clean slices; refrigerate for 30 minutes for easier cutting.

Tips for Perfect Brownies Every Time

Even with great chocolate, small details matter. First, always weigh your ingredients—especially chocolate and flour—for consistent results. Second, line your baking tin with parchment paper that overhangs on two sides; this makes lifting the brownies out effortless. Third, if you want a shiny, crackly top, beat the eggs and sugar for a full 3–4 minutes until thick and ribbony. That aeration creates the classic crust as the brownies bake.

Finally, consider adding mix-ins that complement your chocolate. For the Ecuador 85%, try toasted walnuts or a swirl of caramel. For the Madagascar 72%, dried cherries or orange zest enhance the fruity notes. And if you’re using the Double Sourdough & Sea Salt 66%, a handful of dark chocolate chips (from the same bar) adds extra gooey pockets. Store brownies in an airtight container at room temperature for up to 5 days—they actually get fudgier on day two.

• Weigh ingredients for accuracy.
• Beat eggs and sugar thoroughly for a crackly top.
• Experiment with mix-ins that match the chocolate’s flavour profile.

Baking with Pump Street chocolate elevates your brownies from everyday treats to artisan creations.
