Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Grease a small 6-inch round cake pan with cooking spray.
  2. Step 2: In a medium bowl, whisk together 1/2 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, 1/2 cup granulated sugar, 1/2 tsp baking powder, and 1/8 tsp salt until no lumps remain.
  3. Step 3: Add 1/4 cup milk, 2 tbsp vegetable oil, and 1/2 tsp vanilla extract to the dry ingredients. Mix with a whisk until smooth, then fold in 2 oz melted dark chocolate until fully incorporated.
  4. Step 4: Pour batter into the prepared pan and smooth the top with a spatula. Bake for 20-22 minutes until a toothpick inserted into the center comes out clean. Cool in the pan for 10 minutes before inverting onto a wire rack to cool completely.

Frequently asked questions

How long does Half-Portion Chocolate Cake take to make?

Total time is about 37 minutes (15 min prep + 22 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Half-Portion Chocolate Cake?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Half-Portion Chocolate Cake?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Half-Portion Chocolate Cake for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Half-Portion Chocolate Cake?

American desserts like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
