Mini chips give better coverage in every bite.

FAQ
Can I use quick oats instead of rolled oats?
Yes.
Quick oats make the bars a bit softer and more uniform. If you prefer a heartier texture, stick with rolled oats or use a mix of both.
What kind of protein powder works best?
Whey or a neutral plant-based protein both work. If using pea or brown rice protein, you may need 1–2 extra tablespoons of milk to keep the batter moist.
How do I make these nut-free?
Use sunflower seed butter and choose chocolate chips made in a nut-free facility.
The flavor shifts slightly but stays delicious.
Can I reduce the sweetener?
You can cut the honey or maple syrup to 1/4 cup and add 1–2 tablespoons more milk for moisture. The bars will be less sweet but still tasty, especially with chocolate chips.
Do these bars freeze well?
Absolutely. Wrap individually, freeze, and grab as needed.
They thaw quickly and hold their texture.
