Mastering Cinnamon Protein Bars: How-To

1. Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your bars will bake evenly and rise perfectly.
2. Prepare the Baking Pan
Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides. This will help you lift the bars out easily once they are baked.
3. Mix the Dry Ingredients
In a large mixing bowl, combine the oat flour, coconut flour, vanilla protein powder, 1 tablespoon of cinnamon, and 2 tablespoons of sugar. Stir these ingredients together until they are well combined.
4. Combine the Wet Ingredients
In a separate bowl, mix together the almond butter, brown rice syrup (or maple syrup), vanilla extract, and almond milk. Stir until the mixture is smooth.
5. Combine Wet and Dry Ingredients
Pour the wet ingredients into the bowl with the dry ingredients. Use a spatula to mix everything together until a thick dough forms. Make sure there are no dry patches left.
6. Spread the Mixture in the Pan
Transfer the dough into the prepared baking pan. Use a spatula to spread it evenly, pressing down firmly to ensure the mixture sticks together.
7. Add the Cinnamon Sugar Topping
In a small bowl, mix together the remaining 1 tablespoon of cinnamon and 2 tablespoons of sugar. Sprinkle this mixture evenly over the top of the bars.
8. Bake
Place the pan in the preheated oven and bake for 20-25 minutes, or until the edges are golden brown. The center should be set but slightly soft.
9. Cool and Slice
Remove the pan from the oven and let it cool completely in the pan. Once cooled, lift the bars out using the parchment paper and slice them into squares.
Budget & Availability Swaps
- Oat flour can be made by grinding rolled oats in a blender or food processor.
- Coconut flour can be substituted with more oat flour or almond flour if needed.
- Almond butter can be replaced with peanut butter, cashew butter, or sunflower seed butter for a nut-free option.
- Brown rice syrup can be swapped with agave nectar or honey for a different flavor.
Easy-to-Miss Gotchas
- Ensure your almond butter is well-stirred if it’s natural, as the oil can separate.
- Do not overbake; the bars will continue to firm up as they cool.
- Press the mixture firmly into the pan to avoid crumbly bars.
- Check for doneness by inserting a toothpick; it should come out clean or with a few crumbs, not wet batter.
