Prep the pan: Heat your oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment for easy release.
Whisk dry ingredients: In a large bowl, whisk almond flour, baking powder, salt, and your granulated sweetener until no clumps remain.
Mix wet ingredients: In a separate bowl or measuring cup, whisk eggs, almond milk, melted butter or coconut oil, vanilla, and any optional extracts or zest.
Combine: Pour the wet mixture into the dry ingredients. Stir until just smooth.
The batter will be slightly thick but pourable.
Fill the pan: Spread the batter evenly in the prepared pan. Tap the pan once on the counter to settle the batter.
Bake: Bake for 22–28 minutes, until the top is set and golden around the edges. A toothpick should come out mostly clean with a few moist crumbs.
Cool: Let the cake cool in the pan for 10 minutes.
Run a knife around the edge, then turn it out onto a rack and cool completely.
Finish and serve: Dust with powdered sweetener, add berries, or top with lightly sweetened whipped cream. Slice and enjoy.
