The Chocolate Porter Cake is more than just a sweet treat; it’s a lesson in how a savory ingredient—porter beer—can elevate a dessert. The maltiness adds depth, while the full‑fat Greek yogurt and butter keep the crumb tender. The final cream‑cheese frosting provides a tangy counterpoint that cuts through the richness, making each bite feel balanced rather than cloying.
Ingredient Highlight
Below is the complete ingredient list, taken directly from the recipe JSON. Each component is explained so you understand why it matters and how you can tweak it if needed.
Dry Ingredients
- 50 g cocoa powder – Gives the cake an intense chocolate backbone without adding extra fat.
- 280 g plain flour – Provides structure; the moderate amount keeps the crumb light.
- 2½ tsp bicarbonate of soda – Reacts with the acidity of the porter and yogurt to create lift, ensuring the cake rises evenly.
Sugars
- 200 g caster sugar – Fine‑grained sugar dissolves quickly, contributing to a smooth batter.
- 200 g soft light brown sugar – Adds a subtle caramel note and moisture, thanks to its molasses content.
Fats & Moisture
- 250 g unsalted butter – Delivers richness and helps emulsify the batter.
- 100 g dark chocolate (70 % cocoa solids), chopped into chunks – Melts into the batter, intensifying chocolate flavor.
- 150 g full‑fat Greek yogurt – Adds tang and moisture; the acidity also works with the bicarbonate for lift.
- 200 ml double cream – Used in the frosting for a silky, luxurious finish.
Liquids & Flavor Boosters
- 260 ml porter (St Peter’s Old‑Style Porter or Guinness recommended) – The star ingredient; its malt and roasted notes keep the crumb moist and impart a faint bitterness that balances sweetness.
- 2 large free‑range eggs – Bind the batter and trap air for a light texture.
- 2 tsp vanilla bean extract – Enhances overall aroma and rounds out the chocolate‑porter flavor.
Frosting Essentials
- 200 g full‑fat cream cheese (Philadelphia recommended) – Provides a tangy, creamy base for the frosting.
- 80 g icing sugar – Sweetens the frosting while keeping it spreadable.
Baking Essentials
- Sunflower oil for greasing – Prevents the cake from sticking to the tin.
- Deep 23 cm loose‑bottomed cake tin – Allows the cake to rise freely and release easily after cooling.
- Baking paper – Lined inside the tin for a clean release and easy removal.
Pro tip: If you can’t find a loose‑bottomed tin, use a standard 23 cm springform pan. Grease and line it the same way, then release the sides after cooling.
Step‑by‑Step Instructions
The method is presented exactly as it appears in the source JSON, reformatted into a clean, numbered list for easy following.
- Preheat & Prepare the Tin
- Heat the oven to 180 °C (or 160 °C fan / gas mark 4).
- Grease a deep 23 cm loose‑bottomed cake tin with sunflower oil and line the interior with baking paper.
- In a large pan, gently warm the porter, butter, and dark chocolate together until the butter and chocolate have fully melted, stirring occasionally to prevent scorching.
- Combine Dry Ingredients & Incorporate Wet Mix
- In a large bowl, whisk together the cocoa powder, caster sugar, and light brown sugar, rubbing away any lumps.
- Gradually pour the warm chocolate‑porter mixture into the dry ingredients, whisking vigorously with a balloon whisk until the blend is smooth.
- Add the eggs one at a time, whisking after each addition until the batter thickens and becomes glossy.
- Fold in the Greek yogurt, vanilla bean extract, plain flour, and bicarbonate of soda. Mix until just combined—over‑mixing can lead to a dense crumb.
- Bake the Cake
- Transfer the batter into the prepared tin, smoothing the top with a spatula.
- Bake for 1 hour or until a skewer inserted into the centre comes out clean.
- Allow the cake to rest in the tin for 5 minutes, then carefully turn it out onto a wire rack to cool completely.
- Prepare the Cream‑Cheese Frosting
- While the cake cools, place the cream cheese, icing sugar, and double cream into a large bowl.
- Beat with an electric mixer just until the mixture holds its shape. Do not over‑beat—the frosting will become runny if over‑mixed, and adding more icing sugar will not fix the texture.
- Once the cake is fully cooled, swirl the frosting over the top, allowing it to cascade down the sides for a rustic, elegant finish.
Serving Suggestions & Variations
Classic Presentation
- Dust with cocoa powder or a light sprinkling of instant coffee granules for a decorative contrast.
- Serve each slice with a scoop of vanilla bean ice cream or a dollop of whipped cream to add a cool, creamy element that complements the cake’s richness.
Pairings
- Beverage: Pair the Chocolate Porter Cake with a glass of the same porter used in the batter, or with a dark stout for an extra malt‑forward experience.
- Fruit: Fresh berries (raspberries, blackberries, or sliced strawberries) provide acidity that cuts through the dense chocolate, brightening the palate.
Flavor Twists
| Variation | How to Adapt |
|---|---|
| Orange‑Zest Porter Cake | Add 1 tbsp freshly grated orange zest to the batter (step 2) and a splash of orange liqueur to the frosting for a citrusy lift. |
| Espresso‑Infused | Replace ½ cup of the porter with ½ cup strong brewed espresso; keep the remaining porter for malt balance. |
| Nutty Crunch | Fold in ½ cup toasted chopped hazelnuts or walnuts after step 2 for added texture. |
| Gluten‑Free | Substitute the plain flour with a 1:1 gluten‑free flour blend and ensure the baking powder is gluten‑free. |
| Vegan | Use vegan butter, coconut yogurt, and a vegan cream cheese alternative; replace eggs with flax‑egg (1 tbsp ground flaxseed + 3 tbsp water per egg). |
Storage
- Room temperature: Keep the frosted cake in an airtight container for up to 2 days.
- Refrigerated: For longer storage (up to 5 days), cover tightly and let it come to room temperature before serving.
- Freezing: Slice the cake, wrap individual pieces in plastic wrap, then place in a freezer bag. Thaw overnight in the fridge for a fresh‑tasting treat.
