Preheat your oven to 350°F (175°C).

Grease a 9-inch round cake pan.

In a large bowl, mix the almond butter and sugar until smooth.

Add the eggs one at a time, beating well after each addition.

Stir in the cocoa powder, baking soda, salt, and vanilla extract.

Pour the batter into the prepared cake pan and smooth the top.

Bake for about 25-30 minutes, or until a toothpick inserted into the center comes out clean.
