My husband’s favorite cookie is Monster Cookies made with lots of peanut butter so we make them more then we should. This weekend we made a batch and wanted to get creative with a variety of ways to use this Monster Cookie dough. Today I am giving you the recipe that I have modified over the last few months. I found the original recipe online and decided to make a lot of changes to it. So this is my version of the Monster Cookie. I will also provide the way we got creative; Monster Cookie Ice Cream Sandwich and Monster Cookie Brownie Cups.

The 2 other creative ways we used the Monster Cookie dough was for Ice Cream Sandwiches and Monster Cookie Brownie Cups.

The Ice Cream Sandwiches were so delicious! All you do is add ice cream to your cookie once they are done baking and cooling. I really enjoyed eating the ice cream on a warm cookie but it was messier because the ice cream melted quicker.

The Monster Cookie Brownie Cups were by far our favorite way to use the Monster Cookie dough! We made brownie mix from scratch but you can use a box mix for brownies if you prefer. The brownie recipe we used will be at the very bottom of this post.

Step 2. Place cupcake liners in the pan

Step 3. Place a 1/8 cup of cookie dough into the cupcake liners and press it down so it evenly fills the bottom of the cup.

Place 1/8 cup of cookie

Step 4. Pour in the brownie batter on top of the cookie until the cupcake liner is almost full. (Brownies do not rise like cake so it can be fuller than a regular cupcake).

Step 5. Bake for 45 minutes
