I'm back with another copycat recipe. This time, it's Fiber One Brownies, where my version has the exact same calories, protein, fat, net carbs, and (most importantly) fiber as the store bought version. What my bars are lower in is ingredients, using much simpler, cleaner, and less refined ingredients than the ultra-processed store bought snacks. Additionally, these taste far better, and are half the price! If you want to make some other copycat recipes, check out the links below:

- 1 cup (120 g) Whole wheat flour
- 6 tbsp (80 g) Granulated monk fruit
- 1/3 cup (67 g) Inulin
- 1/2 cup (40 g) Cocoa powder
- 1/2 tsp (3 g) Baking powder
- 1/2 tsp (3 g) Salt
- 5 tbsp (80 g) Almond butter
- 1 cup (240 g) Water

1. Preheat your oven to 350F. Line a 9" square pan with parchment paper, and lightly grease the paper with oil

2. In a large bowl, whisk together the dry ingredients - flour, inulin, monk fruit, cocoa powder, baking powder, and salt

3. To make Fiber One Cookie Bars instead, replace the cocoa powder with powdered peanut butter

4. Add in the wet ingredients (almond butter and water), and combine with a silicone spatula until combined and you have a thick but liquidy brownie batter

5. Pour the batter into your prepared pan

6. Bake at 350F for about 30 minutes, or until a toothpick comes out nearly clean

7. Allow to cool for at least 30 minutes in the pan in the fridge before cutting into 16 bars
