Step 1: Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: In a large mixing bowl, combine the two boxes of cake mix, softened butter, eggs, and vanilla extract. Use your electric mixer to blend the ingredients together until the dough is smooth and well combined.
Step 3: Using a cookie scoop, portion out the dough onto your prepared cookie sheet. Leave enough space between each cookie, as they will spread while baking.
Step 4: Place the cookie sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked, but they will continue to firm up as they cool.
Step 5: Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. Then, transfer them to a cooling rack to cool completely.
Step 6: In a separate bowl, beat together the softened butter, powdered sugar, vanilla extract, and heavy cream until smooth and creamy. If desired, add food coloring to achieve your preferred color.
Step 7: Once the cookies are completely cool, use a spatula or a piping bag to frost each cookie. Feel free to get creative with your frosting techniques!
Step 8: If you want to add sprinkles, do so while the frosting is still wet, so they stick well.
