There’s nothing quite like the combination of chocolate and peanut butter, and these peanut butter protein bars serve as the ultimate healthy snack that can be whipped up in under 10 minutes! I enjoy storing these bars in the fridge (or freezer) and simply taking one when I need a snack or a post-workout boost. They are far superior to store-bought options, which often have an unpleasant chalky texture and taste. These are delightful and significantly healthier for you!

Reasons to Love this Recipe

  • Each bar is loaded with 9 grams of protein, making it a fantastic healthy snack that you can prepare weekly!
  • Ready in just 10 minutes without any need for baking.
  • Utilizes a few ingredients to create tasty protein bars that far surpass the flavor (and health benefits) of store-bought varieties.
  • This recipe can also be adapted to create peanut butter protein balls or protein cookie dough!

Essential Ingredients

  • almond flour – a nutrient-rich flour that is abundant in protein, aiding the bars in maintaining their shape. If you have a nut allergy, feel free to substitute it with oat flour.
  • peanut butter – I prefer natural creamy peanut butter without added sugars, but any nut butter or sunflower butter can be used if you have a nut allergy.
  • protein powder – you can use your preferred plant-based protein powder or whey protein powder in these bars. Vanilla protein powder or other flavors like chocolate, peanut butter, or cinnamon also work well.
  • honey – naturally sweetens the bars without refined sugars and helps bind them together; maple syrup or other natural sweeteners are alternatives.
  • milk – I opted for unsweetened almond milk, but any milk variety will work in this recipe.
  • vanilla extract – adds a delightful flavor kick!
  • chocolate chips – I used Lily’s chocolate chips, which are gluten-free and sweetened with stevia for lower sugar content. You can also choose Lily’s dark chocolate chips or your preferred variety.

How to Prepare Peanut Butter Protein Bars

  1. Combine the ingredients. In a large bowl, combine the almond flour, protein powder, peanut butter, honey, milk, and vanilla with a spatula until thoroughly mixed. Gently fold in the chocolate chips.
  2. Pour into pan. Transfer the batter into an 8×8 baking pan lined with parchment paper, pressing the mixture down firmly with a spatula. You may sprinkle additional chocolate chips on top if desired.
  3. Chill. Place the dish in the refrigerator and let the bars chill for 30 to 60 minutes before slicing. Alternatively, you can put the pan in the freezer for about 25 minutes until firm.
  4. Slice into bars. Cut into 16 squares (or larger bars if you prefer) and store in the refrigerator in a sealed, airtight container until you’re ready to enjoy. These bars will remain fresh for up to 2 weeks.

Recipe Variations

  • Make into balls – you can easily transform these homemade protein bars into tasty peanut butter protein balls! Follow the recipe as directed and then roll the mixture into 2-inch balls. Keep them in a sealed container in the fridge to maintain their shape.
  • Enjoy as cookie dough – the peanut butter protein mixture is quite similar to cookie dough, so why not enjoy it as such? Just stir all the ingredients together, refrigerate, and indulge in a scoop now and then for a sweet treat.
  • Nut-free – swap almond flour with oat flour and substitute peanut butter with sunflower seed butter to make these bars nut-free!
  • Vegan – to convert these bars into a vegan option, replace honey with maple syrup and use dairy-free chocolate chips.
  • Additional mix-ins – consider adding chopped nuts, chia seeds, or flaxseed meal for added fiber, or drizzle melted chocolate on top for a richer dessert!

Prepping and Storing Tips

To Store: These bars should be kept in the refrigerator to maintain their shape. Store them in a sealed, airtight container for up to 2 weeks or take them directly from the freezer and enjoy once thawed for a few minutes.

To Freeze: These peanut butter protein bars are also suitable for freezing, lasting up to 2 months. Just let them thaw for a few minutes at room temperature prior to consuming.
