Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup rolled oats
½ cup protein powder
1 tablespoon cocoa powder
1 tablespoon espresso powder
1 cup almond butter
¼ cup honey
2 tablespoons coconut oil
1 tablespoon chia seeds
½ teaspoon vanilla extract
¼ cup mini dark chocolate chips

Directions

Add oats, protein powder, cocoa powder, and espresso powder to a food processor. Blend for 1 minute until oats are finely ground.
Add almond butter, melted coconut oil, honey, and vanilla to the processor. Blend for 30 seconds, or until the mixture is fully combined.
Pinch the dough between your fingers—it should hold together without crumbling. If crumbly, add a splash of water and blend again.
Add the chocolate chips and pulse just 1–2 times to mix them in evenly.
Line a 9×5-inch loaf pan with parchment paper. Press the mixture evenly into the pan, smoothing the top.
Chill in the refrigerator for 2 hours or freeze for 30 minutes until firm.
Once set, slice into bars and enjoy!

FAQs

Can I use quick oats instead of rolled oats?

Yes, but the texture may be slightly softer. Rolled oats give a more substantial bite.

What type of protein powder works best?

Any protein powder works—whey, plant-based, or collagen. Use your favorite for flavor and nutrition.

Is espresso powder necessary?

No, but it adds depth and enhances the chocolate flavor. You can omit or replace with instant coffee powder.

Can I reduce the sweetness?

Yes, reduce the honey or replace it with a sugar-free syrup if preferred.

Can I skip the food processor?

Not recommended. A processor ensures the right texture by blending oats and evenly distributing the ingredients.

Can I make these bars without chocolate chips?

Absolutely. You can swap in chopped nuts, dried fruit, or omit them entirely.

How do I prevent the bars from crumbling?

Ensure the mixture is moist enough to hold together. Add a bit of water if it feels too dry before pressing into the pan.

Are these bars gluten-free?

Yes, if you use certified gluten-free oats and check your protein powder for gluten.

Can I double the recipe?

Yes. Use an 8×8-inch pan and adjust chilling time if necessary.

Are these bars kid-friendly?

Yes! The chocolate and subtle espresso flavor are balanced enough for older kids, especially if you reduce or omit the espresso powder.
