Banana High-Protein Cookie Skillet
No oat flour. No almond milk. No "protein chef" nonsense.
Cheat-Code Lore
Bananas are the ultimate lazy-baker cheat code — they replace the flour, replace the sugar, and add the moisture, all in one ingredient everyone already has sitting on the counter.

Default Portion: the whole skillet — this is a personal dessert, not a share plate
✂️ Trim Trim Trim
There's no fat to trim here — the whole recipe is built to avoid adding fat in the first place. Banana, whey, and PB2 do all the work that butter and flour would otherwise be doing.
Ingredients
Use-what-you’ve-got friendly.
Sorted by dish, with the spices you probably already own kept separate.
- ◆½–1 overripe banana, mashed
- ◆1 scoop vanilla whey protein
- ◆2 tbsp powdered peanut butter (PB2)
- ◆1 tbsp monk fruit or sugar substitute
- ◆1–2 tbsp milk (any kind — Fairlife, 1%, 2%, whatever's in the fridge)
- ◆¼ tsp baking soda
- ◆Pinch of salt
- ◆½ tbsp chocolate chips (optional)
Instructions
- 1
Mash the banana in a small oven-safe skillet or ramekin.
- 2
Stir in whey protein, PB2, sweetener, milk, baking soda, and salt until it forms a thick batter.
- 3
Fold in chocolate chips if using.
- 4
Bake at 350°F, 10–12 min, until the edges set and the center stays gooey — or microwave 60–90 sec for an even faster version.
🧠 Why This Works
Banana brings natural sweetness, moisture, and enough starch to bind everything without needing any flour at all. Whey protein sets up like a cakey structure when it hits heat, so you get real cookie texture, not protein-powder chalkiness.
🌶️ Flavor Boosters
Cinnamon in the batter • extra chocolate chips • a drizzle of extra PB2 paste on top after baking
🔄 Use What You’ve Got
- —No vanilla whey? Chocolate whey works too, just adjust sweetness to taste
- —No PB2? Real peanut butter works but adds real fat — 1 tbsp adds about 90 cal, 8g fat
- —No monk fruit? Any sugar substitute, or a teaspoon of real sugar (+15 cal)
