fudge filled cookies

Raise your hand if you want cookies and just don’t have time to make them? That’s me too! I’ve solved that problem for you because this recipe is made with store-bought cookie dough! It doesn’t get any easier than that and I promise nobody will ever know because these are amazing!

This is an award-winning recipe! I actually won a Kitchen Aid mixer with these! Part of winning meant that I had to make these cookies for the whole Junior High at our school! Don’t worry, that’s only about 100 kids!

We all know that peanutbutter and chocolate is the BEST combination! To get even more of it check out No-Bake Peanut Butter Pretzel Cookies, Peanut Butter Hot Fudge Sauce, Fudgy Peanut Butter Banana Brownies, Chocolate Chip Peanut Butter Cookies, Peanut Butter Popsicles, Classic No Bake Cookies, Peanut Butter Pretzel Bark, and Peanut Butter Popcorn.

How to Make Peanut Butter Fudge Bar Cookies

If you are feeling ambitious go ahead and use your favorite homemade peanut butter cookie recipe! If you’re feeling frazzled and short on time please don’t feel guilty about skipping taking a shortcut and using a package of cookie mix (Betty Crocker or Pillsbury are great) or a tube of cookie dough from the fridge section of the grocery store! After one bite you’ll feel better about it anyway!

STEP 1: Preheat oven to 350 degrees. Line a 9 x 13 baking pan with aluminum foil. Spray with nonstick baking spray.

STEP 2: Mix cookie dough according to package directions. Spread ½ of it on the bottom of the prepared baking pan. Set aside.

STEP 3: Make the fudge layer. Add sweetened condensed milk, butter, and chocolate chips to a saucepan. Cook over medium heat until all ingredients are melted and combined. Add vanilla. Pour over the first layer of peanut butter cookie dough. You can add chopped walnuts or pecans to add crunch if you want!

STEP 4: Add the top layer of dough. Drop remaining dough over fudge layer. I like to drop it in about Tablespoon sized pieces. You can flatten the pieces out before setting them on the fudge layer if you like. Don’t worry about having spots of the fudge layer that are still exposed. It will be just fine!

STEP 5: Bake for 25 minutes.

STEP 6: Cool. Remove from pan and cut into squares. Store them in an airtight container at room temperature for up to 2-3 days.

      March 28, 2017 at 10:08 am

      Homemade cookie dough would be fantastic in these! I’m not exactly sure how many cups are in one of those little packages/tubes of cookie dough. I used two packages which would have made a total of 36 cookies. Maybe that will give you a guide for finding a recipe that would be about equal in portion. I’m guessing it was about 5 cups of cookie dough in all. Hopefully that helps!

    I just made these for a teacher appreciation lunch for tomorrow. It is all I can do to NOT cut into them tonight. Tomorrow before I bring them in (already cut into squares), I will have to have one for quality control purposes. 🙂 This seems like a wonderful combination of peanut butter blossom cookies (I use the same mix – Betty Crocker) with the filling of the fudgey-oatmeal squares. I may have to get up early tomorrow.

      Hi Sandy! I used two bags of peanut butter cookie mix. One for the top and one for the bottom. Each mix was 17.5 ounces, which makes a total of 35 ounces. These cookies are pretty thick! I just updated the recipe so it’s a little more clear. Hopefully, that helps!
