HOW TO MAKE CRUNCHY EGG WHITE COOKIES

Being baked twice these meringue based cookies remind of biscotti. Truth is I don’t know where this delicious cookie recipe originated except that my grandmother and then my mom used to make the cookies whenever they had leftover egg whites. And now, I make them too.

INGREDIENTS

  • Egg Whites
  • Powdered Sugar
  • All Purpose Flour
  • Walnuts or Pecans, Hazelnuts, Almonds
  • Vanilla Extract
  • Cream of Tartar or Lemon Juice
  • Salt

BAKING PAN

These cookies are first baked in a Rehrucken Moravian Loaf Pan/Ribbed Loaf Pan. If you are not sure if you should get one, I also like using this pan for my ice box cakes, like my Chocolate Banana Ice Box Cake. Butter and flour baking pan with flour and shake out the excess, (steps 1-2).

TIP : If you don’t have a ribbed baking pan you can also use a loaf baking pan instead.

TOASTED NUTS

Pour walnuts into a skillet and toast on medium high, until walnuts are fragrant. This can take about 5-10 minutes. Allow nuts to cool and then roughly chop them up, just to break up the big pieces.

Can I use other nuts? Yes, absolutely. You can use other nuts : try almond, hazelnuts or pecans.

MERINGUE

To make the meringue make sure your mixing bowl is spotless. I like to wipe it with a paper towel and little bit of vinegar, to remove any traces of fat. Then pour in room temperature egg whites. Don’t forget to add some cream of tartar or freshly squeezed lemon juice or vinegar before you beat the egg whites. Why should you use cream of tartar to make meringue?

Beat egg white until soft peaks are formed, (step 1). Then gradually beat in powdered sugar. Continue beating meringue until stiff and glossy peaks are formed, (steps 2-6).

To flavor meringue I use Vanilla Extract. You can use other extracts just be sure to use either alcohol or water base flavorings. Oily/candy flavorings will break down the meringue, (steps 7-8).

MERINGUE BATTER

When I thought about it, these crunchy egg white cookies are basically made from a thick angel food cake batter. Why haven’t I thought about it before?!

To prepare meringue batter all you need to do is add flour into the meringue, along with the nuts for extra flavor.

Into the flour add a pinch of salt and whisk together, (steps 1-2).

Now gradually, in 3 additions fold sifted flour into the stiff and glossy meringue. Make sure to fold the flour, don’t stir. Meringue will deflate some but that’s okay, (steps 1-8).

BAKE

Spoon the meringue batter into a prepared loaf pan. Smooth the top with a spatula, (steps 1-4)

Bake at 350F (180C) for 30minutes or until golden around the edges and a toothpick inserted in the center comes out clean, (steps 1-2). Invert baked loaf onto a foil and wrap it well. Let it cool for couple hours. It helps to soften nuts a bit so it’s easier to slice thru them, (steps 1-4).

SLICE COOKIES

Slice the loaf with a serrated knife into about 1/8″ inch (3 mm) slices. I was able to get 54 slices out of one loaf.

Without the second baking cookies stay rubbery so be sure to dry them before you serve them to avoid the disappointment.

Layer cookies flat on baking sheets and bake them at 300F for 10-15 minutes, or as needed to dry them out. They should be crispy and snap.

Bake cookie slices second time at 300F( C) for 10-15 minutes, until dry. Cookies should be snappy, they will be chewy if now properly dried. Watch the cookie so they don't burn. Remove from the oven and allow to cool completely before storing.

  1. This was really easy to make and was soooo good! A few slices with a cup of coffee in the morning was the best. They aren’t as sweet as you would think they are. I used almond slivers and was wondering if you have tried adding dried fruit like cranberries. Would the slices stay crispy when stored?

    1. Hi Tina,
      I’m so glad you like these. They are one of my favorite cookies.
      I’m not 100% sure they would stay as crispy as without the dry fruit, but I don’t think they’d get very soft.
      I think I just might try that sometime soon. I’m making them again.
