- 1 cup natural peanut butter (or almond butter)
- 1/2 cup honey or maple syrup

How to Make No Bake Oatmeal Protein Bars
This is the kind of recipe where you don’t need a mixer, fancy gadgets, or even much experience. Just a bowl, a spoon, and some hungry vibes.
Step 1: Mix the wet stuff
In a large bowl, combine the peanut butter, honey (or maple syrup), mashed banana, and vanilla extract. Stir until smooth.
Step 2: Add the dry ingredients
Stir in the oats, protein powder, flaxseed, cinnamon, and a pinch of salt. Mix until everything is evenly combined. The mixture should be thick but pliable.
Step 3: Toss in the extras
Fold in chocolate chips, chopped nuts, or dried fruits if you’re using them.
Step 4: Press into a pan
Line an 8×8-inch baking dish with parchment paper. Press the mixture into the pan using the back of a spoon or your hands. Pack it in tightly so it holds together.
Step 5: Chill and slice
Pop it in the fridge for at least 1 hour (overnight is even better). Once set, slice into bars or squares. Store in the fridge or freezer.
Pro Tips for Best Results
- Use runny peanut butter: If your nut butter is super thick, warm it slightly to make mixing easier.
- No banana? No problem: Just skip it or add an extra 1-2 tablespoons of nut butter.
- Customize the protein: Use any protein powder you love—whey, plant-based, even collagen peptides work.
- Cut with a warm knife: Run your knife under hot water before slicing. It helps get clean cuts without crumbling.
