Equipment
- 1 8x8 inch square baking pan
- 1 Large Mixing Bowl
- Whisk
- Butter Knife
- Large Mixing Spoon
- Measuring cup and spoons
Ingredients
- 1 1/2 cups All-purpose flour
- 3/4 cup Golden Coconut sugar or light brown sugar/regular sugar
- 1 teaspoon Baking soda
- 1/4 teaspoon Fine sea salt
- 1 cup Lukewarm Water can substitute regular milk or plant based milk (almond or oat)
- 1/3 cup Avocado oil or vegetable/canola oil
- 1 tablespoon Vinegar apple cider vinegar or white vinegar
- 2 teaspoons Pure vanilla extract
- 2 tablespoons Unsweetened cocoa powder sifted
- 1 tablespoon Water (or milk)
Glaze Ingredients
- 1/2 cup Chocolate chips
- 1 tablespoon Avocado oil or other Vegetable oil
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease your 8x8-inch square baking pan with a tiny bit of oil or cooking spray, or line it with parchment paper for easy removal.
- In a large mixing bowl, stir together the all-purpose flour, coconut sugar, baking soda, and salt with a whisk or fork until completely combined and free of large clumps.
- Pour the water (or regular milk), avocado/vegetable oil, vinegar, and vanilla extract straight into your dry ingredients. Stir vigorously with a flexible spatula or whisk for about 45 to 60 seconds just until a smooth, glossy vanilla batter forms and all flour streaks disappear.
- Transfer roughly one cup of your smooth vanilla batter into a separate small bowl or measuring cup. Sift the two tablespoons of unsweetened cocoa powder and add the extra tablespoon of water directly into this separated amount. Stir well with a spoon until it transforms into a rich, dark, cohesive chocolate batter.
- Add the remaining vanilla batter directly into the bottom of your prepared 8x8 pan, using your spatula or small spoon to spread it evenly into the corners. Next, take your chocolate batter and drop it by the spoonful in large, random dollops on top of the vanilla layer.
- Use a simple butter knife or a wooden skewer. Place the tip in the batter all the way to the bottom of the pan, and drag it through the chocolate and vanilla layers in a continuous "figure-eight" motion across the pan just a few times. Be sure not to over-mix, or the colors will blend into a solid brown instead of distinct swirls!
- Pop the pan onto the center rack of your oven and bake at 350°F (175°C) for 25 to 28 minutes. Test the center by pressing it gently with a finger; it should spring back immediately, and a toothpick inserted into the middle should come out completely clean. Remove from the oven and let the pan rest on a wire rack until completely cooled to room temperature.
Chocolate Glaze Instructions
- Place a half-cup of chocolate chips and one tablespoon of avocado or other preferred oil into a small, completely dry microwave-safe bowl. Microwave at fifty percent power in thirty-second bursts, stirring in between until completely melted and shiny. Use a spoon to drizzle dramatic zig-zag patterns across the top of the cooled cake, let the chocolate set for several minutes, then slice into nine even squares to reveal the incredible hidden marble swirls inside!
Notes
Smart Sugar Substitutions: If you don't have golden coconut sugar on hand, you can substitute it with an equal amount of light or dark brown sugar. Because brown sugar contains natural molasses, it mimics the moisture content and deep, warm caramel flavor notes of coconut sugar without altering the delicate texture of the cake crumb. Traditional granulated cane sugar also works perfectly, though the cake will have a more classic, straightforward sweetness.
Cocoa Powder Alternatives: This recipe is calibrated using premium, high-fat natural cocoa powder, but it's highly versatile! You can easily swap it 1:1 with standard grocery store unsweetened cocoa powder. If you prefer a deeper color contrast for your marble swirls, Dutch-process cocoa powder also works amazingly here and will not deflate your cake's eggless rise.
The Sifting Rule for Cocoa: Natural cocoa powder naturally forms tiny, dense clumps inside the canister. Always make sure to sift your two tablespoons of cocoa powder through a small mesh strainer or fluff it thoroughly with a fork before stirring it into your separated vanilla batter. This ensures a perfectly smooth chocolate batter with no hidden bitter pockets!
