Why you’ll love this recipe!
What ingredients do I need?
- Medjool dates: natural sweetness and chewy texture.
- Natural creamy peanut butter: adds richness, protein, and binding.
- Peanuts: crunch and natural nut oils.
- Cashews: creamy texture and subtle flavor.
- Dry milk powder: boosts creaminess and protein.
- Protein powder: your choice of whey, plant based, or collagen for an extra protein boost.
- Salt: balances sweetness.
- Vanilla extract: adds depth of flavor.
- Cocoa powder: chocolatey richness.
- Water: helps mixture stick together if needed.
Recipe Variations
- Chocolate Chunk: add in some dark chocolate chunks, or ground cacao nibs, at the end for that added chocolate flavor and texture
- Nut variety: Use your favorite nuts. Swap cashews with almonds, or peanuts with walnuts, etc.
- Sprinkle sea salt on top before chilling for a sweet-salty twist.
- Roll mixture into balls instead of bars for protein bites.
Pro Tips
- Pulse the nuts first before blending with the rest of the ingredients. This will help the texture and avoid large chunks of nuts which will also prevent it from crumbling as much.
- Firm pressing is key! Make sure you press the mixture tightly into the pan to prevent crumbling.
- These bars release natural oils from the nuts, which can feel greasy. A quick blot with a paper towel fixes it without affecting taste.
- If your mixture seems dry, add water 1 tsp at a time; if too wet, add a little extra protein powder or cocoa.
- Wrap each bar individually in parchment paper and then store in an airtight container in the fridge for 1–2 weeks or freeze for longer.
- Chill thoroughly before slicing for clean slices; a warm knife works best if sticking does occur.
Can I Substitute?
Yes! Like always though, any substitutions made to the recipe can result in a change in texture and/or flavor.
- Nuts: Swab the peanuts and/or cashews with your nut of choice!
- Vegan: Swap dry milk powder for a plant-based milk powder.
- Nut butter swap: Almond or cashew butter works instead of peanut butter.
Dietary Substitutions
- Gluten free: Naturally gluten free if using certified gluten free protein powder.
- Paleo friendly: Skip protein powder and dry milk, increase nuts and dates slightly.
- Nut free: Replace the peanut butter with sunflower butter and then nuts with pumpkin seeds or sunflower seeds.
Leftovers and Storage
- Store in an airtight container in the fridge for up to 2 weeks.
- Freeze individually for up to 3 months.
- Blot excess oil with a paper towel if needed; it’s normal and doesn’t affect taste.
But, I Still Have A Few Questions…
Can I split the bars into smaller portions?
Yes! Cut the 8 bars into 16 squares instead!
Why do these bars feel greasy?
The natural oils from the peanuts and cashews surface over time, which is normal. Blot with a paper towel, if desired.
Can I freeze these bars?
Absolutely! Wrap individually in parchment or plastic wrap and freeze up to 2–3 months. Let them thaw at room temperature for 10–15 minutes.
How long do bars last in the fridge?
Up to 1–2 weeks in an airtight container.
Can I make them vegan or nut free?
Yes! Use seed butters and plant based milk powder. See the substitutions section above.
Can I use flavored protein powder?
Vanilla or chocolate-flavored powders work well; adjust cocoa powder accordingly.
