Heath bar blondies

The Christmas countdown is on! Can you believe that Christmas will be here in less than two weeks?! There’s a lot to pack into these last few weeks before our family gathers together—shopping for stocking stuffers, wrapping gifts, and planning menus.

However, for the first time in several years, I’m feeling pretty accomplished with my Christmas preparations. Most of the shopping is done and our house is decorated, so now I can focus on stocking the fridge and baking cookies!

This year, I’m adding these delicious Heath Bar Blondies, a chocolate-topped sweet dessert bar studded with Heath Bar toffee bits inside and out, to my cookie swap menu.

Like most families, we have our favorite traditional shaped and cut-out cookies, but I also like baking bar cookies, and I especially love today’s easy recipe.

The cookie base is a rich, dense blondie with Heath Bar toffee chips in the batter. After baking, simply sprinkle semi-sweet chocolate chips on the warm cookie bars and then spread to frost the top and sprinkle with more Heath Bar toffee bits.

To make cutting the bars easier, chill in the fridge for 20 minutes.

I love how festive and warm our house feels after all the Christmas decorations go up! Two years ago, a helpful floral designer at The Great Christmas Shop gave me a few pointers on how to start build the tree topper with springs of berries, sparkly greenery, burlap poinsettias and ribbon.

Even so, I had to search for last year’s photos to remind me exactly how to do it! Every year I add a little more to fill in the tree. Last year it was gold twig-like balls from Pier One and this year I added classic red and gold glass ornaments.

Now, I’m ready to focus on my baking and menu planning so that when the kids get home we can focus on enjoying being together and celebrating the greatest gift of all—Jesus.

Cookie bars are great dessert options for parties and picnics because they are easy to transport, but most importantly they’re always popular and tasty, too!

Hi, Pamela! I'm not very experienced with using almond flour as a substitute, so I couldn't tell you what kind of results you might get.
