How to Use This Tool
Enter the total number of cookies your recipe makes, then fill in the grams of flour, butter, sugar, and the number of whole eggs. Optionally add protein powder and nuts (in grams) if your recipe includes them. Click "Calculate Protein" to see the protein per cookie, total batch protein, and estimated calories per cookie. Use the Reset button to clear results and restore default values.
Formula Explained
The calculator uses average protein densities per 100g of each ingredient:
- All-purpose flour: ~10 g protein per 100g
- Butter: ~0.85 g protein per 100g
- Sugar: 0 g protein
- Whole egg: ~12.5 g protein per large egg (50g)
- Protein powder (whey/plant): ~80 g protein per 100g
- Mixed nuts (almonds/walnuts): ~20 g protein per 100g
Total protein = sum of (ingredient weight × protein fraction). Then divide by number of cookies. Calories are estimated using standard Atwater factors: flour 3.64 kcal/g, butter 7.17 kcal/g, sugar 3.87 kcal/g, egg 72 kcal each, protein powder 4.0 kcal/g, nuts 5.7 kcal/g.
Worked Examples
12 cookies, 200g flour, 100g butter, 150g sugar, 1 egg, no extras.
Protein = (200×0.10 + 100×0.0085 + 150×0 + 1×12.5) / 12 = (20 + 0.85 + 0 + 12.5) / 12 = 33.35 / 12 ≈ 2.8 g per cookie.
18 cookies, 250g flour, 80g butter, 120g sugar, 2 eggs, 30g protein powder, 50g peanuts.
Protein = (250×0.10 + 80×0.0085 + 120×0 + 2×12.5 + 30×0.80 + 50×0.20) / 18 = (25 + 0.68 + 0 + 25 + 24 + 10) / 18 = 84.68 / 18 ≈ 4.7 g per cookie.
Tips for Boosting Protein in Cookies
- Replace up to 30% of flour with protein powder (adjust liquid slightly).
- Add chopped nuts, seeds (hemp, chia), or nut butters.
- Use Greek yogurt or cottage cheese in place of some butter (reduces fat, adds protein).
- Incorporate egg whites or liquid egg whites for extra protein without fat.
Frequently Asked Questions
How accurate is this calculator?
It provides a good estimate based on average ingredient compositions. For precise values, refer to the nutrition labels of your specific brands.
Can I use this for gluten-free or vegan cookies?
Yes, but substitute the protein values accordingly. For example, almond flour has ~21 g protein per 100g, while coconut flour has ~19 g. Vegan butter and egg replacers will have different protein contents.
Why does my cookie have less protein than calculated?
Possible reasons: using low-protein flour (pastry flour ~8%), not weighing ingredients accurately, or protein powder that is blended with fillers.
Does baking affect protein content?
Protein content remains largely unchanged during baking, though slight denaturation occurs. The total grams of protein stay the same.
