Ingredients
  

Instructions
 

  • Prepare a loaf pan by lightly greasing it with butter or cooking spray, then lining it with parchment paper, leaving some overhang for easy removal.
  • In a mixing bowl, combine the nut or seed butter and liquid sweetener until smooth.
  • Add the protein powder and sprinkles (if using) to the bowl. Mix with a wooden spoon or spatula until the ingredients form a thick, dough-like consistency. If the mixture is too dry, add water or milk one tablespoon at a time until the desired consistency is reached. If it's too wet, add more protein powder.
  • Press the mixture firmly into the prepared loaf pan, using your hands or a spatula to spread it evenly. Add additional sprinkles on top, if desired, and press them into the mixture.
  • Refrigerate or freeze the bars for at least 15 minutes to firm up before slicing.
  • Cut into 6 large bars or smaller bite-sized pieces as preferred.

Notes

A NOTE ABOUT PROTEIN POWDER:
You can use various types of protein powders in this recipe, including whey, casein, or plant-based options like pea, hemp, or soy protein. Each type has different absorption rates, so you might need to adjust the liquid content to achieve the right consistency. For a flavor that closely matches the birthday cake theme, look for birthday cake or vanilla-flavored protein powders. If using a vegan protein powder, you may need to slightly modify the quantities as plant-based proteins can sometimes absorb liquids differently.
 
TIPS & NOTES:
  • Adjusting Consistency: If the mixture is too dry, add water or milk one tablespoon at a time. If too wet, add more protein powder.
  • Nut-Free Option: Use tahini or sunflower seed butter for a nut-free version.
  • Sweetener Options: Honey, maple syrup, agave, or date syrup work well. Adjust to your sweetness preference.
  • Customization: Add mix-ins like chocolate chips, dried fruit, or nuts for extra flavor and texture.
  • Storage: Keep bars in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 2 weeks, or freeze for up to 3 months.
 
MEASUREMENTS:
 
I always recommend using a kitchen weighing scale and using weighted measurements. This will result in a more accurate process and your cheesecakes will come out perfectly.
