1-First Step: Set out all ingredients to reach room temperature. This ensures even mixing for smooth dough in your chocolate lofthouse cookies recipe. Preheat oven to 350°F and line baking sheets with parchment paper to prevent sticking.

2-Second Step: In a large bowl, beat 1/2 cup softened butter, 4 oz softened cream cheese, and 1 cup sugar with an electric mixer on medium speed until light and fluffy, about 2-3 minutes. This incorporates air for tender soft chocolate cookies. Scrape down sides for even creaming.

3-Third Step: Add 1 egg, 1/2 cup sour cream, and 1 tsp vanilla extract. Mix on low until combined, avoiding overmixing to maintain moisture in these copycat lofthouse cookies. Room-temp items blend seamlessly, preventing curdling.

4-Fourth Step: In a separate bowl, whisk 2 cups flour, 1/3 cup cocoa powder, 1/2 tsp baking soda, and 1/4 tsp salt. Gradually add dry mix to wet ingredients, stirring gently with a spatula until just combined. Dough will be soft and sticky, perfect for chocolate frosted cookies.

5-Fifth Step: Cover dough and chill in the fridge for 1 hour. This firms it up, making scooping easier and preventing spread for bakery-style chocolate sugar cookies. Patience here yields professional results.

6-Sixth Step: Scoop 2-tablespoon mounds of dough, roll into balls, and place 2 inches apart on prepared sheets. Flatten slightly if desired. Bake at 350°F for 10-12 minutes until edges set but centers look underdone. Cool on sheets 5 minutes, then transfer to racks.

7-Seventh Step: For frosting, beat 1/2 cup softened butter until creamy. Gradually add 2 cups powdered sugar, 1/4 cup cocoa powder, 2 tbsp milk, and 1 tsp vanilla, mixing until spreadable. Spread 1-2 tbsp on cooled cookies, swirling for that lofthouse cookies vibe.

8-Final Step: Add sprinkles if desired and let set 30 minutes. Yields 24 easy chocolate lofthouse cookies. Store as noted below. For vegan adaptations, use substitutes mentioned earlier; gluten-free works straight swap.
