Ingredient Notes & Substitutions
A few small ingredient choices can change the flavor and texture slightly.
Protein powder
Vanilla and chocolate protein powders both work well. Choose one you enjoy because the flavor will come through.
Nut butter
Peanut butter makes the bars rich and creamy, while almond butter gives a milder flavor.
Honey vs maple syrup
Honey creates slightly firmer bars, while maple syrup keeps them softer.
Oats
Rolled oats work best because they create a chewy texture.

Pro Tips for Success
A few simple tricks help these bars turn out perfectly.
Press the mixture firmly
Compact bars hold together better when sliced.
Adjust moisture if needed
If the mixture seems dry, add a tablespoon of milk.
Chill before cutting
Cold bars slice more cleanly.
Use parchment paper
This makes removing the bars from the pan effortless.

They taste great straight from the fridge or slightly softened at room temperature.
Make Ahead & Freezing

- Freeze extras for later weeks.
I often double the recipe so there are always a few ready after workouts.
