Brownies, Blondies and More: 7 Outrageously Good Bar Cookies

Easy to make, and even easier to eat, bar cookies make perfect party desserts. From Millionaire's Shortbread to boozy Cheesecake Brownies, these bars will blow your taste buds away. Happy Holidays!

1. Millionaire's Shortbread

Known as Millionaire's Shortbread, presumably because they are so rich, these bars consist of a layer of crumbly shortbread, a layer of soft caramel and a layer of chocolate. To me, they taste just like gourmet Twix bars. GET THE RECIPE

2. Luscious Lemon Squares

A crisp and buttery shortbread crust topped with lemon filling and powdered sugar, these bars are as pretty as they are delicious. GET THE RECIPE

3. Baileys Cheesecake-Marbled Brownies

Spiked with Baileys Irish Cream, these brownies with a swirl of tangy cheesecake are cakey on the bottom, alternately fudgy and creamy in the center and crisp on top. The marbled top makes them look elaborate but they're simple to make. GET THE RECIPE

4. Chocolate Chip Pecan Blondies

Part cookie, part brownie -- who doesn't love blondies? And the best part is that they're ridiculously easy to make: fewer ingredients than cookies (plus you don't have to roll the dough into balls) and easier than brownies because there's no chocolate to melt. This version, made with chocolate chips and pecans, is my all-time favorite. GET THE RECIPE

5. Supernatural Brownies

If you've been searching for the perfect brownie recipe, look no further. I promise you, this is it! The recipe comes from Nick Malgieri's Chocolate cookbook, an excellent resource for all things chocolate. GET THE RECIPE

6. Chocolate Peanut Butter Squares

With a chocolate cookie crust, rich and creamy peanut butter layer, and smooth-as-silk milk chocolate topping, these squares are simply to-die-for. GET THE RECIPE

7. Pecan Shortbread Squares

If you're a fan of pecan pie, you're going to love these pecan squares. A buttery shortbread crust and rich caramel-pecan topping make them truly over-the-top -- the perfect hostess gift, treat for your co-workers or potluck dessert this time of year. GET THE RECIPE
