Walnut Frosties

I have no idea where the name Walnut Frosties originated, but my friend Margaret shared a batch of these cookies with us a while back, and with the very first bite, I asked her if she’d pretty please share the recipe with me.

She was kind enough to do so and now I’m willing to bet that you’re going to love these Walnut Frosties every bit as much as we do!

The cookie is a brown sugar drop type of cookie. The brown sugar and butter combination makes for the perfect cookie base for the nutty filling.

The filling combination of walnuts, sour cream, and brown sugar bakes up into a sweet Brulee-like crust on top of the buttery cookie.

To achieve the perfectly filled cookie use your thumb or the back of a melon baller to create a circular indent in the cookie. Then fill the cookie with the walnut filling. Don’t be afraid to overfill just a bit as it will bake down and fill the indentation nicely.

If your cookies spread too much while baking chances are your butter was too soft when you started. If the dough seems too soft to me I like to bake a test pan with 2-3 cookies on it first to see how much they spread. Refrigerate the dough for 30 minutes or so to firm it up if it spreads too much.

My friend shared that traditionally they make these at Christmas. She had no clue why, it was just what they do. However as delicious as they are I am making them year around!

Brown Sugar Walnut Cookies

  1. Preheat the oven to 350°F. Cream together butter and sugar until smooth and combined. Mix in the egg and vanilla. Sift the flour, baking soda, and salt. Add to the wet ingredients.
  2. In a separate bowl combine the chopped walnuts, ½ cup of brown sugar and the sour cream.
  3. Using a 1½ inch cookie scoop place scoops of dough on a silpat or parchment lined baking sheet. Make a thumbprint indentation into each cookie and fill with a generous teaspoon of the walnut filling.
  4. Bake for 11-12 minutes until just starting to turn brown. Remove from the oven and let cool for 5 minutes on the baking sheet. Place cookies on a wire rack to finish cooling.

Cookies and cookie recipes are meant to be shared. Whether it is taking a plate to the neighbors or trading recipes with friends. It doesn’t get much better than sharing all things cookies over a cup of coffee.

It is no secret that I keep a full cookie jar. I have a house full of boys constantly on the prowl for a snack. Oatmeal cookies are such a versatile classic. The nuttiness of the oatmeal and sweet chocolate hit the spot when the mid-afternoon munchies come on.

You only need a handful of ingredients to make these chewy, chocolate and peanut butter-filled Peanut Butter Cookie Cups.

Crisp and chewy at the same time, the best Monster Cookie recipes are loaded with all of my favorite great cookie flavors. Oats, peanut butter, chocolate chips, and even a drop of maple syrup all combine to make my grandmother’s Monster Cookies.

    Hi! These are the best!! However, I’ve been struggling with making the indent with the back of the cookie scoop and the dough sticks to it :>( I tried using a smidgen of nonstick spray but the cookies came out flat and a little greasy. Any suggestions? Thank you!!!5 stars

    • Mary Younkin says

      If you dampen the scoop with just water (or just use your thumb) it may work better for you. I’m glad you’re enjoying the cookies and hopefully we can make them a little less fussy for you!

    These r the best cookies I’ve ever made!! Everyone that had some wands more!! What a great recipe!!! Thank you thank you!!! 😊5 stars

  3. Joyce Mitchell says

    I made these tonight; they are very good and delicious. I think I would make them again for an occasion rather than as a weekly cookie because they are very rich and my fridge is not very big.4 stars

    recipe looks good – am going to make a batch shortly and have high hopes – would be easier to work the recipe if you listed ingredients with weights (grams) rather than just by volume – many of us feel weighing out ingredients gives a better result – sally’s baking addiction is a great site that does this – just a suggestion……
