A crispy sugar cookie topped with cinnamon and sugar and filled with rich brown butter. A delicious cookie brittle perfect for gifts and snacks! Tastes just like snickerdoodle cookies!
My two year old knows Costco. I consider "knowing Costco" where you can find all the samples. It's like a game for her. Suddenly you'll be walking down an aisle and she shouts out, "I found un!" She'll point to the direction we need to head to...stat. Other times, she surprises me. "Mom, dares un! I smwell it." If I don't head in the right direction, she will practically throw herself out of the cart while dramatically using arm gestures to show me exactly where I need to be heading.
The Costco ladies smile and give her another sample. By the time we get out of the store she's usually had the equivalent of lunch and dinner and my arms are sore from trying to keep her in the cart with one hand while precariously lifting two gallons of milk into the cart with the other. And don't even get me started on if there isn't a sample available. Oh, we wait or come back. 
One thing I love about Costco are the unique products they sell. One day we ran across a rather large bag (because is ANYTHING normal sized at Costco?) of cookie brittle. It looked delicious but I rarely buy anything on a whim at Costco. Simply because one of two things happens: I buy it and find I like/love it and eat the whole bag then causing feelings of guilt and remorse or I buy it, end up not liking it and end up hating that I spent money on something I didn't like which also causes feelings of guilt and remorse. 
When I saw this cookie brittle I knew I could try it at home before I bought a bag. And I'm glad that I did. It is delicious!
Ingredients
- 4 egg whites
- 1 cup granulated sugar
- ½ cup + 2 tbsp butter, melted
- 1 tsp pure vanilla extract
- ½ tsp salt
- ½ tsp baking powder
- ½ tsp cream of tartar
- ½ tsp cinnamon
- 1 ⅛ cup whole wheat flour
- 2 tbsp sugar
- 2 tsp cinnamon
Instructions
- Preheat oven to 325 degrees.
- Line a baking sheet or jelly roll pan with parchment paper or silpat.
- In a mixing bowl, whisk the egg whites until they become foamy. (If using an electric mixer do this on medium speed). Turn the mixer to low and stir in the sugar, melted butter and vanilla until smooth. Stir in the salt, baking powder, cream of tartar, cinnamon, and whole wheat flour until smooth.
- Pour the batter onto the baking sheet or jelly roll pan and smooth with a scraper, spoon, or rolling pin until batter is ⅛-1/4 inch thick.
- Mix together the 2 tbsp of sugar and 2 tsp of cinnamon and sprinkle evenly over the top of the cookie batter.
- Bake at 325 degrees for 17 minutes. The edges of the cookie batter should be brown. Remove from the oven and immediately cut into pieces with a pizza cutter or knife into uneven pieces.
- For any soft chewy pieces remaining, return them to the oven and bake an additional 10-15 minutes until browned and hard. Remove from oven and allow to cool.
