Step-by-Step Instructions (Detailed)

Step 1: Prep the Pan & Oven

• Preheat your oven to 350°F (175°C).

• Grease a 9-inch round cake pan with olive oil, then line the bottom with parchment paper. Lightly oil the parchment as well to prevent sticking.

• Tip: If you skip the parchment, the cake might stick because olive oil-based batters are delicate.

Step 2: Combine Dry Ingredients

• In a large mixing bowl, whisk together:

  • 1 cup all-purpose flour

  • ½ cup unsweetened cocoa powder

  • 1 tsp baking soda

  • ½ tsp salt

• Whisk for 30 seconds to break up lumps and fully distribute the baking soda and salt. This ensures even rising and prevents pockets of bitterness from undissolved cocoa.

Step 3: Mix Wet Ingredients

• In a separate large bowl, add:

  • ¾ cup granulated sugar

  • ½ cup extra-virgin olive oil

  • 2 large eggs

  • 1 tsp vanilla extract

• Whisk briskly for 1 minute until the mixture looks smooth, glossy, and slightly pale. This step incorporates air for a lighter crumb.

• Common mistake: If you see oil separating, whisk a bit more until it fully emulsifies.

Step 4: Add Coffee & Milk

• Heat ¾ cup brewed coffee until hot (not boiling).

• Slowly pour the coffee into the wet mixture while whisking gently. Then add ½ cup milk (or almond milk).

• Whisk until smooth. The mixture will look very thin—this is correct and ensures a moist cake.

• Tip: Pour liquids down the side of the bowl to prevent splashes.

Step 5: Combine Wet & Dry Mixtures

• Make a well in the dry ingredients and pour in the wet mixture.

• Whisk slowly, starting from the center and moving outward, until no dry streaks remain.

• Switch to a spatula for the last few folds to avoid overmixing (overmixing can create a dense cake).

• Optional: Fold in ½ cup dark chocolate chips for extra richness.

Step 6: Bake

• Pour the batter into the prepared pan—it should look loose and pourable.

• Tap the pan gently on the counter to release any air bubbles.

• Bake for 35–40 minutes. Start checking at 35 minutes:

  • Insert a toothpick into the center; it should come out with a few moist crumbs (not wet batter).

• Avoid opening the oven door too early; this can cause the cake to sink.

Step 7: Cool & Serve

• Remove from oven and let the cake cool in the pan for 10 minutes.

• Run a thin knife around the edges to loosen, then invert onto a wire cooling rack.

• Peel off the parchment and let the cake cool completely (at least 1 hour) before slicing.

• Serving ideas: Dust with powdered sugar, drizzle with ganache, or top with berries and cream.
