A thick, creamy, slightly chewy cookie dough packed with nostalgic flavor and an easy, no-bake method that comes together in minutes.
For me, cookie dough is one of those classic comfort foods. Last time I did a Biscoff Cookie Dough.
This moster cookie dough is no different, dotted with chocolate and colorful candy pieces.
It delivers that same indulgent look and texture, but with a macro-friendly twist that fits beautifully into a low carb lifestyle.

Ingredients You Need
Vanilla whey-casein protein blend (60g) This is essential for the thick, dough-like texture. A whey-casein blend works best because whey alone can turn sticky and casein alone can get too dense. Substitution: You can use whey isolate, but expect a softer, slightly runnier result.
Oat flour (30g) Adds structure and gives that classic cookie dough body. For strict keto, swap with finely ground almond flour—but note the texture will be slightly more crumbly and less chewy.
Powdered peanut butter (15g) Provides flavor without excess fat. You can substitute almond powder or omit entirely, but you’ll lose that “monster cookie” flavor depth.
Zero calorie sweetener (1 tbsp) Adjust to taste. Powdered erythritol, monk fruit blends, or allulose work well. Avoid granulated sweeteners unless you blend them first—they can leave a gritty texture.
Pinch of salt Do not skip—this balances sweetness and enhances flavor.
Sugar-free pancake syrup (1 tbsp) Adds moisture and sweetness. You can substitute sugar-free maple syrup or a little liquid sweetener. Avoid honey if keeping it keto.
Butter extract (1/2 tsp) This is a secret flavor booster. It mimics that classic cookie dough richness without extra fat.
Skim milk (1/2 cup, added slowly) Essential for texture. Add gradually to avoid making the dough too thin. For keto, use unsweetened almond milk—but expect a slightly lighter texture.
Mini chocolate chips (2 tsp) Use sugar-free chocolate chips to keep carbs low. Regular chips will increase carb count.
Mini M&Ms (2 tsp) Optional and not keto-friendly. Swap with sugar-free candy pieces or extra chocolate chips if needed.
Step-by-Step Directions
Combine dry ingredients In a medium bowl, whisk together the protein powder, oat flour, powdered peanut butter, sweetener, and salt until evenly mixed. This step prevents clumping later.
Add liquid ingredients Stir in the sugar-free syrup and butter extract until the mixture starts to come together.
Add milk gradually Slowly pour in the skim milk, a little at a time, mixing continuously. Texture cue: Stop when the dough becomes thick, smooth, and scoopable, not runny.
Fold in chocolate chips Gently stir in the mini chocolate chips so they’re evenly distributed.
Chill briefly Transfer the dough to a bowl and freeze for 10 minutes. This step is key, it firms up the texture and enhances that cookie dough consistency.
Add toppings and serve Sprinkle mini M&Ms (or keto alternatives) on top just before serving for the best texture and visual appeal.
Tips for Success
- Do not add all the milk at once This is the fastest way to ruin the texture. I’ve done it—and ended up with protein pudding instead of dough.
- Use a whey-casein blend if possible This creates the ideal structure. Whey-only powders tend to get sticky and less dough-like.
- Watch your sweetener choice Some sweeteners dry out the mixture. If your dough feels crumbly, add a splash more milk or syrup.
- Chill is not optional The 10-minute freeze transforms the texture from soft batter to true cookie dough.
- Avoid overmixing after adding milk Mix just until combined to keep the dough soft and not rubbery.
Frequently Asked Questions
Can I make this fully keto?
Yes. Replace oat flour with almond flour, use unsweetened almond milk, sugar-free chocolate chips, and skip M&Ms. This significantly lowers net carbs.
How many net carbs does this have?
With the original ingredients, net carbs are higher due to oat flour and candy. With keto swaps, expect around 8–12g net carbs per serving.
How do I store this cookie dough?
Store in an airtight container in the refrigerator for up to 4 days. It will firm up slightly, just let it sit at room temperature for a few minutes before eating.
Can I freeze it?
Yes. Freeze for up to 1 month. For best texture, thaw slightly before eating so it becomes soft and scoopable again.
