Ingredients
Cake
- 1 cup (320 grams) honey* or 2 cups (375 grams) coconut sugar or 2 cups (400 grams) granulated sugar
- 1 3/4 cups (210 grams) whole spelt flour, whole wheat flour, white whole wheat flour, all-purpose flour or 1 3/4 cups (236 grams) Bob’s Red Mill 1-to-1 gluten-free baking flour for a gluten-free version
- 3/4 cup (85 grams) cocoa powder (Dutch-process preferred)
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs (50 grams each, out of shell) or 2 chia eggs** for vegan version
- 1 cup (240 milliliters) milk of choice***
- 1/2 cup (120 milliliters) olive oil or another neutral-tasting vegetable oil liquid at room temp
- 2 teaspoons vanilla extract
- 1 cup (240 milliliters) boiling water
Chocolate Avocado Frosting
- Flesh of 1 avocado (155 grams)
- 1/2 cup + 2 tablespoons (72 grams) Dutch-process cocoa powder
- 1/2 cup + 2 tablespoons maple syrup (about 162 milliliters)
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- 2 tablespoons (28 grams) refined coconut oil
Instructions
- Preheat Oven: If using honey, preheat your oven to 325 °F (167 °C). If using coconut sugar or granulated sugar, preheat to 350 °F (175 °C). This accounts for honey’s tendency to bake quicker than sugar.
- Prepare Cake Pans: Line two 8-inch round cake pans with parchment paper on the bottom, then grease the sides to prevent sticking.
- Mix Dry Ingredients: In a large bowl, stir together the chosen sugar (if using honey, don’t add it yet), flour, cocoa powder, baking powder, baking soda, and salt to combine thoroughly.
- Add Wet Ingredients: Add the eggs (or chia eggs), milk, honey (if using), olive oil, and vanilla extract to the dry ingredients. Mix on medium speed for 2 minutes. Then, carefully stir in the boiling water. The batter will be very thin but will bake to a moist texture.
- Divide Batter: Split the batter evenly between the two prepared cake pans.
- Bake: Bake the cakes for 25-30 minutes. Check doneness by inserting a toothpick; it should come out with some moist crumbs but no raw batter. Bake time may vary depending on ingredient choices.
- Cool: Allow the cakes to cool completely, about 1 hour, before applying frosting. Cakes can be stored at room temperature for 2 days, refrigerated for 3 days, or frozen for up to 3 months.
- Prepare Frosting: In a high-speed blender or small food processor, blend avocado flesh, cocoa powder, maple syrup (start with 1/2 cup), vanilla extract, salt, and refined coconut oil until smooth. Taste and add up to an additional 2 tablespoons of maple syrup for desired sweetness.
- Frost Cake: The frosting yield is about 2 cups plus 1 tablespoon, enough to layer and top a two-layer 8-inch cake. Apply about 3/4 to 1 cup between layers and the remainder on top. If the frosting hardens after refrigeration, gently reheat to soften before spreading.
- Storage: Cover and refrigerate the finished cake for up to 2 days. Non-avocado frostings last slightly longer (up to 3 days). The cake also freezes well for up to 3 months.
Notes
- * Honey yields a moister cake but requires lower baking temperature to prevent over-browning.
- ** Chia eggs: Mix 1 tablespoon ground chia seeds with 3 tablespoons water per egg and let gel for 5-10 minutes, suitable for vegan baking.
- *** Milk of choice can be dairy or any plant-based milk like almond, soy, or oat milk for vegan adaptation.
- The boiling water thins the batter significantly and helps develop a moist crumb despite the whole grain flours.
- The frosting’s avocado taste is subtle initially but becomes more noticeable after 1 day refrigerated.
- Use refined coconut oil in frosting for a neutral flavor and smooth texture.
- For gluten-free option, use a 1-to-1 gluten-free baking flour and chia eggs instead of traditional eggs.
- Ensure cake is fully cooled before frosting to prevent melting.
- Reheat frosting gently if too firm from refrigeration to aid spreading.
