Ingredients

Dry

1 ¼ cups fine almond flour
¼ cup unsweetened cocoa powder

2 tsp baking powder
¼ tsp baking soda
¼ tsp salt

Wet

3 large eggs
¼ cup avocado oil (or light olive oil)
¾ cup unsweetened almond milk (start with ¾; see batter note)
2 tsp vanilla extract
1 tsp apple cider vinegar (or white vinegar)

Optional (Recommended)

2–3 tbsp brewed coffee (deepens chocolate flavor)

Frosting

¾ cup plain Greek yogurt (or coconut yogurt)

Directions

Preheat & Prep

Preheat oven to 325°F.
Line an 8-inch round pan with parchment on the bottom; lightly grease sides.

Mix Dry

In a large bowl whisk: almond flour, cocoa, ISO-WHEY, sweetener (if using), baking powder, baking soda, salt.

Mix Wet

Add eggs, oil, almond milk, vanilla, vinegar (and coffee if using).
Whisk until smooth.

Check Batter

Let batter sit 2 minutes (whey thickens as it hydrates).
Batter should be like a thick pourable cake batter.
If it’s very thick, whisk in 1–2 tbsp more almond milk.

Bake

Pour into pan, smooth top.
Bake 25–32 minutes.
Done when a toothpick comes out with moist crumbs (not wet batter).

Frosting

Spread frosting mix on top. Chill 15 minutes to firm up.

Cool

Cool 10 minutes in pan, then transfer to rack.
Slice after fully cooled (texture improves as it sets).

Recipe Note

Sweetness note

If you use a sweetened/flavored ISO-WHEY, you may need little to no extra sweetener.
If you use Unflavored/Unsweetened, you’ll likely want ¼–⅓ cup sweetener total (to taste).

Other Notes

Don’t overbake (whey dries out fast).
Bake at 325°F for a gentler rise + softer crumb.
Use fine almond flour (not coarse almond meal).
