Combine wet ingredients: In a large mixing bowl, whisk together the eggs and sour cream until smooth and well combined, about 1 minute.
Add melted butter: Stir in the melted butter and mix until the wet ingredients are fully incorporated.
Mix dry ingredients: In a separate bowl, whisk together the almond flour, baking powder, salt, garlic powder, and Old Bay seasoning if using.
Fold together: Gently fold the dry ingredients into the wet mixture until just combined, then fold in the shredded cheddar cheese until evenly distributed throughout the batter.
Preheat oven: Preheat your oven to 350°F and line a baking sheet with parchment paper.
Scoop batter: Using a cookie scoop or spoon, drop rounded portions of batter onto the prepared baking sheet, spacing them about 2 inches apart.
Bake: Place in the preheated oven for 20-25 minutes, until the biscuits are golden brown on top and firm to the touch.
Cool slightly: Remove from the oven and let the biscuits cool on the baking sheet for 5 minutes before transferring to a wire rack.
