STORAGE & FREEZING : 4 Ingredient Peanut Butter Cups (Protein Recipe)
These peanut butter cups keep well in the fridge and freezer.
- In the fridge: Store in an airtight container for up to 2 weeks. Place a piece of parchment between layers so they do not stick.
- In the freezer: Lay them in a single layer on a tray to freeze for one hour. Then move them to a freezer-safe container or bag. They keep for up to 3 months. To thaw, move them to the fridge for 15 to 30 minutes or leave at room temperature for a few minutes.
For best texture, take cups from the freezer and let them sit for a short time before eating. Do not leave them at room temperature too long or the chocolate will soften and the filling may leak.

FAQs
Q: How many calories are in one peanut butter cup?
A: Calories depend on the exact brands you use. As a rough guess, one small cup made with the listed amounts has about 80–120 calories. Use the nutrition label on your ingredients to get a precise number.
Q: Can I use regular peanut butter instead of powdered peanut butter?
A: Yes, but the texture and calories will change. If you use regular peanut butter, you may need less water or no water at all, and you should reduce the total fat in the mix. Start with one tablespoon of peanut butter per cup and adjust.
Q: What type of protein powder works best?
A: Any plain or vanilla whey, casein, or plant protein will work. Use a powder that mixes well with water for a smooth filling. Avoid powders with heavy flavors that might clash with peanut butter or chocolate.
Q: Can I make these nut-free?
A: To make nut-free cups, use a seed butter powder (like sunflower seed powder) and a safe seed butter in place of peanut butter. Check the labels to ensure no cross-contact if you need them to be free from peanuts or tree nuts.
Q: Can I melt the chocolate on the stove?
A: Yes. Use a double boiler or place a heat-safe bowl over a pot of simmering water. Stir until smooth and then use as directed.
Q: Will the texture be grainy with powdered peanut butter?
A: Powdered peanut butter can be grainy if not mixed well. Add water slowly and whisk until smooth. Let it sit for a minute and stir again to remove any lumps.
MAKE-AHEAD TIPS FOR 4 Ingredient Peanut Butter Cups (Protein Recipe)
You can make these cups up to three months ahead if you freeze them. Freeze them on a tray first, then move to a bag or box. Label the container with the date. If you want to make them a day ahead, make them the night before and keep them in the fridge in an airtight container.
For quick prep, pre-measure the dry peanut butter and protein powder and store them in a small jar. When you want cups, add the water and mix, then warm the chocolate and assemble. This saves time and keeps your kitchen clean.
If you need to make a larger batch, double or triple the ingredients and use more muffin liners or a larger mold. Work in stages: melt one bowl of chocolate, fill many liners, freeze, then finish. The process scales well and stays simple.
