Cinnamon Roll Cookie Cups

Preheat oven to 350 degrees F. Grease a muffin pan. Combine brown sugar and 8 tbsp melted butter and whisk together. Add egg and vanilla extract. Combine dry ingredients (flour, baking powder, 1/4 tsp salt, 1 tsp cinnamon) into a bowl and fold into wet ingredients. Scoop cookie dough into muffin pan and press down to make a cavity. Bake for 15-17 minutes for larger cups and 10-12 minutes for minis. When you remove cookie cups from oven, use the back of a cookie scoop to re-press down the cavity. Make filling by combining 8 tbsp melted butter, 1 cup light brown sugar, and 1 tbsp cinnamon. Place in a piping bag. Make drizzle by combining 1/2 cup powder sugar and 2 tbsp milk or heavy cream. Place in a piping bag. Pipe filling into each cookie cup and make a little swirl of icing on top!
