When I think of butter cookies, they’re the fancy shaped “Danish” kind which come in a blue tin and which you find at drugstores and such. So when I saw the recipe on the side of the Swan potato starch box for Swedish Butter Cookies, I was expecting something similar – something along the lines of shortbread cookies. Surprise. The resulting cookies were almost identical to Nabisco’s old Brown Edge Wafers which were discontinued many years ago.
It turns out these homemade Brown Edge wafers are better! The potato starch is key. The recipe is on the back of the box, but here’s my Brown Edge Wafers adaptation below. Of course you might as well follow the recipe on the box if it’s still there. They probably alternate recipes. Don’t worry about finding other uses for potato starch, because there are many. You can use it in angel food cake, as a thickener and as a component of gluten-free flour blends.
Brands of Potato Starch & Flavors
Update: I’ve found another brand of potato starch called Streit’s which works well. And since I posted this there are even more brands readily available on Amazon. I’ve only tested with Swan and Streit’s, though. For flavors, people have mentioned the originals had kind of a citrus flavor. While I don’t remember the exact citrus flavor of the originals, the cookies are delicious with a little Boyajian lemon oil or orange oil. Lemon zest or orange zest can also be used. Here’s a photo from my latest batch. This one was made with vanilla paste and about 1/2 teaspoon orange zest.
To Make a Half Batch
If you want to make Brown Edge Wafers but don’t want to commit to a full batch, the recipe halves well. To halve the egg, crack it into a cup, beat it with a fork, then weigh out 24 to 27 grams or measure about 2 tablespoons.
Brown Edge Wafers
- 1 cup butter regular, not unsalted, softened (235 grams)
- 1 cup sugar (200 grams)
- 1 egg (54 grams)
- 1 1/2 teaspoon vanilla
- 1 cup potato starch flour 140 grams**
- 1 cup all-purpose flour (127 to 140 grams)
- Cream together butter and sugar. Beat in egg and vanilla.
- Mix together flour and potato starch flour; add to butter mixture and stir until combined. Chill dough for about an hour.
- Roll into small balls and place on ungreased or parchment lined cookie sheets. Press gently with palm of hand to flatten slightly. Bake at 375 degrees F for 10 minutes or until edges are brown.
