Preheat and prep: Heat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Mix dry ingredients: In a large bowl, whisk almond flour, baking powder, garlic powder, onion powder, salt, and pepper until well combined.
Combine wet ingredients: In a separate bowl, whisk eggs, sour cream, and melted butter until smooth.
Let the butter cool slightly so it doesn’t scramble the eggs.
Bring it together: Pour the wet mixture into the dry ingredients. Stir with a spatula until no dry spots remain. Fold in the shredded cheddar and herbs.
Rest the dough: Let the dough sit for 3–5 minutes.
Almond flour hydrates quickly, and this short rest helps the dough firm up for easier scooping.
Portion the biscuits: Using a large cookie scoop or two spoons, drop 10–12 mounds of dough onto the prepared baking sheet, spacing them a couple inches apart.
Shape and finish: If you want smoother tops, lightly dampen your fingers and pat the mounds into rounded biscuits. Brush the tops with melted butter for extra color.
Bake: Bake for 12–15 minutes, until the tops are golden and the centers are set. The bottoms should be lightly browned.
Cool briefly: Let the biscuits cool on the pan for 5 minutes to set.
Serve warm for the best texture and flavor.
