Plant-Based Protein Bars

Ingredients for Cookie Dough Protein Bars

For about 5 – 7 bars, you’ll need just a handful of basics:

  • Vanilla protein powder → adds the protein boost. Tip: choose a creamy rice or pea protein for best results.
  • Coconut flour or oat flour → helps bind the mixture and adds mild flavor.
  • Erythritol → natural sweetener, no sugar. Adjust to taste.
  • Nut butter (peanut or almond) → creamy texture and extra satiety.
  • Soy or rice crispies → for the crunchy texture + plant-based protein.
  • Almond milk (or other plant-based milk) → brings the dough together.
  • Sugar-free dark chocolate → for dipping or coating, classic protein bar style.

How to Make Plant-Based Protein Bars

Kitchen tools: 1 mixing bowl, spoon/spatula, small baking dish (20×20 cm) lined with parchment paper or use a silicone bar mold, knife.

  1. Mix dry ingredients: Combine protein powder, flour, and erythritol in a bowl.
  2. Add nut butter & milk: Stir in peanut/almond butter and almond milk until a thick dough forms.
  3. Fold in crunch: Gently mix in crispies without crushing them.
  4. Press into form: Spread dough into a lined baking dish and smooth the top.
  5. Chill: Refrigerate for 1 hour until firm and cut the bars.
  6. Optional chocolate coating: Dip bars into melted sugar-free dark chocolate.
  7. Enjoy: Your homemade protein bars are ready, crunchy, healthy, and full of plant-based power!

Choosing the Right Protein Powder

When making protein bars plant based, the protein powder makes a big difference. My tips:

  • Look for a vegan base like pea, rice, or hemp protein.
  • Check for a complete amino acid profile.
  • Choose a powder with natural sweeteners like stevia or erythritol instead of artificial additives.
  • Short ingredients list = better quality.
