Preheat oven to 350°F. Line a baking sheet with parchment paper.
Using a hand-held or stand mixer, beat the Splenda Sweetener and butter together until fluffy.
In a separate bowl, whisk together both flours, baking soda, cinnamon, and salt. Beat the dry ingredients into the butter and sweetener mixture until well-combined. Mixture will be crumbly. With mixer on low, beat in ice water a tablespoon at a time, just until the mixture comes together to form a cookie dough.
Sprinkle some wheat flour on a flat, clean surface on the countertop and roll dough out ¼-inch thick. Use a small teddy bear-shaped cookie cutter to cut dough into teddy bear shapes. Place each cookie 3 inches apart on the baking sheet.
Bake for 10 – 12 minutes, until the edges of the teddy bear are light brown.
Remove and place cookies on a rack to cool. Enjoy, and store extra cookies in an air-tight container.
