Put the butter in a mixer and beat for around 5 minutes till it becomes fluffy. Pour the heavy cream in and continue beating for 2-3 more minutes. Mix in the egg, as well as the finely grated Parmesan, almond flour, and baking soda. Black pepper to taste.
Line some parchment paper on a baking sheet and coat with butter or coconut oil. Plop 1 tbsp of the dough on the baking sheet. Repeat to make about 10-12 balls. Top with the shredded Parmesan cheese.
Leave in the oven for 5-7 minutes. Once the base of the biscuit turns golden brown, transfer to a cooling rack. Serve with the dish of your choice.
