🎅✨ Step-by-Step Recipe Instructions
Yield: 9 big, bakery-style frosted bars
🎄 Step 1: Prep, Glow-Up, & Mix the Wet Ingredients
Preheat your oven to 325°F (165°C) — low and slow is the secret to soft, non-rubbery protein bakes, babe. Line an 8×8 pan with parchment paper, leaving those cute little “handles” so you can lift the bars out later like a pro.
Now grab your mixing bowl and whisk together:
- ½ cup (120g) Greek yogurt
- ⅓ cup (80ml) maple syrup
- 1 large egg white
- 1 Tbsp vanilla extract
- 1 tsp almond extract (the festive ✨ magic ✨)
Whisk for a full minute until the mixture is creamy, smooth, and slightly frothy — this airiness = that soft, tender sugar-cookie texture we love.
🎁 Step 2: Build Your Soft Sugar Cookie Dough Base
Add into the same bowl:
- 1 ½ cups (180g) oat flour
- 2 scoops (60g) vanilla protein powder
- 1 tsp baking powder
- ¼ tsp salt
Fold with a spatula. It’ll look thick and crumbly at first — don’t freak out, that’s the protein powder doing its thing.
Now slowly pour in ¼ cup (60ml) unsweetened almond milk, folding gently until a soft, slightly sticky dough forms. It should press together easily between your fingers.
Too dry? Add 1 more tablespoon of milk.
Too sticky? You’re probably perfect.
Remember: no overmixing. We’re making bars, not yoga mats.
🎀 Step 3: Press, Bake & Cool (Aesthetic Mode: ON)
Transfer your dough into the parchment-lined pan. Lightly wet your fingers or the back of a spoon and press the dough evenly into every corner. This gives you that smooth, Instagram-ready base.
Bake at 325°F for 14–16 minutes. The edges should look the tiniest bit golden, and the top should spring back gently when tapped.
DO. NOT. OVERBAKE.
Dry protein bars are not the vibe.
Let the whole pan cool completely on a wire rack — like 100% cool. If you frost too soon, it’ll slip right off like a bad holiday eyeliner moment.
❄️ Step 4: Whip Your Frosting (Protein Cloud Edition)
In a blender or mini food processor, add:
- 1 cup (240g) cottage cheese
Blend for 60–90 seconds until it’s silky-smooth — no bumps, no curds, just pure cloud-like creaminess.
Move it to a bowl and add:
- 3–4 Tbsp powdered erythritol
- 2 Tbsp vanilla protein powder
- 1 tsp vanilla extract
- Pinch of salt
Using a hand mixer, whip for 2–3 minutes until it goes from runny → fluffy → full-on dreamy frosting cloud.
Too thick? Add almond milk literally one teaspoon at a time until spreadable.
✨ Step 5: Frost, Decorate & Slice the Magic
Once the cookie base is totally cool, spread your whipped frosting evenly across the top — go all the way edge-to-edge for maximum bakery-core vibes.
Shower with festive sprinkles (red + green = Christmas cuteness activated 💅🎄).
Press them down gently so they stay put.
Lift the slab out using your parchment handles, transfer to a cutting board, and slice into 9 perfect, aesthetic squares, wiping your knife between each cut for that clean, TikTok-worthy look.

Storage and Reheating Tips
Storage: Because of the fresh ingredients in the frosting, these bars MUST be stored in an airtight container in the refrigerator. They will stay perfectly fresh and delicious for up to 4-5 days.
Freezing: Yes, you can freeze them! Place the sliced bars in a single layer on a parchment-lined baking sheet and “flash freeze” for 1-2 hours until solid. Then, transfer them to a freezer-safe bag or container. They will keep for up to 2 months. Thaw in the refrigerator overnight before enjoying.
Reheating: These are meant to be enjoyed chilled straight from the fridge! The frosting holds its perfect texture this way.
✨ Serving Suggestions
For the dreamiest holiday experience, pop these bars in the fridge and serve them chilled — that’s when the texture gets ultra-soft, fudgy, and honestly addictive. They look absolutely stunning on a Christmas dessert board, especially surrounded by chocolate-dipped strawberries, mini pretzels, and all your favorite festive treats.
Pair them with:
☕ A cozy mug of hot coffee
🥛 An ice-cold glass of milk (classic cookie moment)
🍃 Peppermint tea for full winter-wonderland vibes
Want to go full extra? Create a DIY Frosting + Sprinkle Bar at your next holiday party. Serve the bars unfrosted and let everyone decorate their own with the protein frosting, holiday sprinkles, crushed candy canes, or even a sugar-free chocolate drizzle. It’s cute, interactive, and totally Instagrammable — the Main Character holiday moment you deserve. 🎀✨
Reader Tips or Helpful Notes
- BLEND THAT COTTAGE CHEESE: I’m saying it again. For a completely smooth, non-grainy frosting, you MUST blend the cottage cheese until it’s silky. Do not skip this!
- Cool Completely: Impatience is the enemy of a beautiful frosted bar. If the base is warm, the frosting will melt and slide right off.
- Use an Electric Mixer for Frosting: While you can whisk by hand, an electric mixer incorporates air and creates a light, fluffy frosting that’s far superior in texture.
- Don’t Over-Bake: The second the edges are golden and the center is set, take them out! They continue to cook as they cool, and over-baking is the main cause of dry bars.
- Wet Your Fingers: The dough is sticky. Wetting your fingers or a spoon to press it down is a game-changer for a smooth top.
- Customize Your Sprinkles: Use whatever sprinkles you love! Pastels for Easter, red and pink for Valentine’s, or just classic rainbow for a birthday vibe.
- Add Lemon Zest: For a lemon bar variation, add the zest of one lemon to the frosting and a tablespoon of lemon juice to the dough.
- Common Mistake – Substituting Flours: Coconut flour will NOT work as a 1:1 sub here. It’s far too absorbent and will create a crumbly, dry bar.
- Common Mistake – Using Runny Liquid Sweetener in Frosting: If you use maple syrup in the frosting, be prepared for it to be much softer. Powdered erythritol gives the best, thickest results.
- For Clean Slices: Use a sharp, thin-bladed knife and wipe it clean with a warm, damp cloth between each cut for perfectly pristine edges.
Recipe FAQs
Q: Can I make this without an electric mixer for the frosting?
A: You can, but the frosting won’t be as light and fluffy. A stand mixer or hand mixer is highly recommended to whip air into the blended cottage cheese.
Q: My frosting is too runny. How can I fix it?
A: Pop the bowl of frosting into the fridge for 20-30 minutes to firm up. You can also add an extra tablespoon of protein powder to help thicken it.
Q: Can I use a different protein powder?
A: A whey/casein blend works best. Vegan protein powders can be used but often result in a drier, more crumbly texture, so you may need to add an extra tablespoon or two of almond milk to the dough.
Q: Are these bars gluten-free?
A: Yes, as long as you use certified gluten-free oat flour, this recipe is naturally gluten-free!
Q: Can I use all-purpose flour instead of oat flour?
A: Absolutely! Use the same amount by weight (180g) for best results, or 1 ½ cups by volume.
Q: Why is my cookie base dry?
A: This is likely due to over-measuring the flour or over-baking. Make sure to spoon your oat flour into the measuring cup and level it off, and set a timer to avoid over-baking.
Q: Is the almond extract necessary?
A: It’s highly recommended for that authentic, bakery-style sugar cookie flavor, but you can omit it and use all vanilla extract if you prefer.
