They usually are. Between the sugar, sweetened peanut butter, and oats, they’re a stealthy carb trap. But not anymore. This version is sweet, rich, and chewy—with zero added sugar and a quick set in the fridge.
💡 What Solves the “Keto But Cookie Craving” Problem
- Sugar-free peanut butter + butter = perfect fudgy base
- Granulated sweetener melts in for true candy texture
- Cocoa powder + oats give you the classic cookie bite without baking
- Fridge set, not oven baked—means fast results and zero burn risk
They’re chewy, firm (not dry!), and rich enough to feel indulgent—without blowing your carbs.
🧾 Ingredients That Kept It Sugar-Free (And Tasty)
- ½ cup butter – Rich base fat, helps set the cookies
- 1½ cups sugar-free sweetener – Granulated allulose or erythritol blends work best
- 1 cup natural sugar-free peanut butter – Check label: no added sugar, just peanuts + salt
- ¾ cup milk – Use almond milk for lower carb count
- ½ cup unsweetened cocoa powder – Deep chocolate flavor
- 3 cups oats – Rolled for classic flat cookies, quick oats for scoopable balls
👉 If you’re keeping it stricter low-carb or keto, swap part of the oats for unsweetened shredded coconut or chopped nuts.
🔁 What You Can (and Can’t) Change
Swap In | For What | Carb Impact | Notes |
---|---|---|---|
Almond milk (¾ cup) | Dairy milk | Lowers carbs | Thinner texture, still tasty |
Almond butter (1 cup) | Peanut butter | Slightly lower | Slightly less sweet taste |
Chopped pecans or coconut | 1–1½ cups oats | Cuts carbs | Use with quick oats to keep texture |
Liquid monkfruit (2 tsp) | Part of sweetener | Zero-carb boost | Round out flavor without grit |
⚠️ What Went Sideways (And How I Fixed It)
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Didn’t set firm | Too much milk or warm butter | Chill longer or reduce milk slightly |
Gritty texture | Used pure erythritol | Blend sweeteners or use allulose |
Oats too chewy | Used rolled oats, didn’t chill | Stick with quick oats for round shape |

❓ Keto Cookie FAQs (Real Answers)
Are oats keto?
Not really, but small amounts can fit into low-carb, not strict keto diets. You can sub with coconut, hemp hearts, or chopped nuts if needed.
Can I make this without peanut butter?
Sure—use almond butter or sunflower seed butter, but adjust sweetness depending on the nut’s flavor.
Do these stay firm at room temp?
They’ll soften, especially if made with almond milk or if your kitchen is warm. Best served chilled.
