THE SPLIT PLATE / RECIPE

Cookie Butter Iced Proffee

Proffee Episode 2 — Ep 1's concentrate-first technique now carries cookie butter and Biscoff. 210 cal / 22g protein per glass (1:9.5 protein-to-cal), 5-minute build. Whey blends into a hot coffee concentrate with a crushed Biscoff cookie, then ice + fat-free ultra-filtered milk + cookie-butter rim + whipped topping + a second Biscoff crumble finish.

EST. / SERVING~210 cal | ~22g protein
KEY TO SUCCESS: Blend whey into the HOT concentrate before adding ice or milk — Proffee-series spine, carries from Ep 1.

Ingredients

BLEND INTO CONCENTRATE

  • 1 Biscoff cookie, crushed (goes INTO the concentrate — 1 more for the top later)
  • 1/2 tbsp instant coffee
  • 1/2 serving unflavored whey isolate (~14g protein — adjust by brand)
  • 2 tsp monk fruit / erythritol sweetener
  • 2-3 tbsp hot water (hot but NOT boiling — start with 2 tbsp, add the third only if needed)

ASSEMBLY

  • Ice, as needed
  • 1/2 cup Fairlife fat-free ultra-filtered milk

FINISH (post-pour)

  • 1 tsp cookie butter spread (for the rim — see step 5 for cleanest application)
  • 1 tbsp sugar-free whipped topping
  • 1 Biscoff cookie, crushed (garnish over the whipped topping)

You want Ep 1's concentrate-first iced protein coffee but flavored up — cookie butter on the rim, crushed Biscoff inside the concentrate for spice depth, whipped topping + a second Biscoff crumble on top. 210 cal / 22g protein per glass at a 1:9.5 protein-to-cal ratio (Ep 1 is 1:5 leaner but plain; Ep 2 is a dressed-up drink at an honest macro line). Ep 2 of Proffee. Same 5-minute build, same technique spine.

Method

  1. 1.CRUSH FIRST BISCOFF. Crush 1 Biscoff cookie into the bottom of a tall blending cup. This cookie goes INSIDE the concentrate for spice depth throughout the drink; the second cookie stays whole for the garnish at the end.
  2. 2.ADD COFFEE + WHEY + SWEETENER. 1/2 tbsp instant coffee, 1/2 serving unflavored whey isolate, and 2 tsp monk fruit sweetener into the blending cup with the crushed Biscoff.
  3. 3.ADD HOT WATER. 2 tbsp hot (NOT boiling) water. Start with 2 tbsp; add the third only if the concentrate needs help moving. Hot water pulls flavor from the crushed Biscoff and dissolves the coffee faster than cold; not-quite-boiling protects the whey from denaturing.
  4. 4.BLEND SMOOTH. Submerge the immersion-blender head BEFORE turning it on (splatter control). Blend until the concentrate is smooth with zero visible protein clumps or Biscoff chunks. This is the Proffee-series technique differentiator — whey dissolves into the hot concentrate NOW, not into cold milk later.
  5. 5.RIM THE SERVING GLASS (recommended). Spread 1 tsp cookie butter around the rim of the SERVING glass while it's still empty — much cleaner than rimming a full drink. The filmed video builds the entire drink in one cup, which works but is harder to keep tidy. If following the video's one-cup method, rim carefully with the drink already in place.
  6. 6.ADD ICE + MILK. Fill the rimmed serving glass with ice. Pour the concentrate over the ice, then add 1/2 cup Fairlife fat-free ultra-filtered milk. Fat-free is the macro-honesty pick — 2% pushes calories without adding protein.
  7. 7.TOP WITH WHIPPED TOPPING. Add 1 tbsp sugar-free whipped topping in a swirl over the drink.
  8. 8.GARNISH + SERVE. Crush the second Biscoff cookie over the whipped topping. Serve immediately — the whipped topping softens against the cold drink after 1-2 minutes.

SPLIT PLATE SERVING

Adult: Serve the adult portion as described above.

Kid: Serve the kid portion as described above.

Keys to success

  • Use hot but NOT boiling water. Boiling denatures whey and creates chalky texture. 2 tbsp is the target; add up to 1 more only if the concentrate isn't moving.
  • Submerge the immersion-blender head BEFORE turning it on. Splatter control.

If something fails

Whey clumps in the finished drink: Concentrate wasn't blended long enough. Blend for another 15-30 sec until fully smooth before adding ice + milk. Adding whey directly to cold milk = permanent clumps.

Coffee flavor is weak: Too much water in the concentrate. Start with 2 tbsp hot water and only add the third tbsp if the mix isn't moving. Verify the instant coffee dose (1/2 tbsp).

Rim smears or looks messy: Rim the SERVING glass empty before pouring — this is the cleanest method and what the recipe recommends. The filmed one-cup method makes the rim harder to keep tidy but still works with careful application.

Cookie butter melts off the rim: Room-temp cookie butter grips the glass better than warm. If the spread is too soft to hold the rim, chill it for 5 min in the fridge before applying.

Whipped topping deflates fast: Add the whipped topping just before serving — sitting against the cold drink softens it within 1-2 minutes. Also verify the whipped topping brand: some sugar-free varieties are less stable than others.

Drink is too sweet / not sweet enough: Cookie butter + Biscoff + whipped topping stack sweetness fast. Start at 2 tsp monk fruit in the concentrate; drop to 1 tsp if the finished drink reads too sweet at first taste. Adjust in the concentrate before blending, never in the finished glass.

Storage and reheating

Store: Best served immediately. The blended concentrate (before ice + milk + toppings) can be refrigerated in a sealed jar for up to 24 hours — reblend briefly if it separates. Cookie butter rim + whipped topping + second Biscoff crumble go on AT SERVING TIME only — none of the finishes hold well pre-assembled.

Reheat: Don't — this is an iced drink. For a hot version, skip the ice and use warm (not boiling) milk over the hot concentrate. Skip the whipped topping and rim for a hot serve — neither holds against heat.

Lasts: Finished drink is best in the first 3-5 minutes. Whipped topping softens against the cold in 1-2 minutes; ice dilutes the flavor over 5-10 minutes. Concentrate alone (no ice/milk/toppings) holds 24 hours refrigerated.

Estimated nutrition

~210 cal | ~22g protein.

210 cal / 22g protein per glass (1 glass per batch — Ep 2 doesn't batch like Ep 1's 2-glass build because the toppings don't hold). Component breakdown per glass: 2 Biscoff cookies (~70 cal / 1g protein) + 1/2 tbsp instant coffee (~2 cal / 0g protein) + 1/2 serving unflavored whey isolate (~55 cal / 14g protein — varies by brand) + 2 tsp monk fruit (~0 cal) + 3 tbsp hot water (0 cal) + 1/2 cup Fairlife fat-free (~45 cal / 6g protein) + 1 tsp cookie butter (~30 cal / 0g protein) + 1 tbsp sugar-free whipped topping (~5-10 cal / ~0g protein) = ~207 cal / 21g protein raw sum. Rounds to the creator-provided 210 / 22 target. Marked estimated. 1:9.5 protein-to-cal ratio — honors the site's 1:10 macro line despite the dessert-drink dress-up.

Flavor target

First sip: caramelized-spice cookie-butter rim hits before the coffee — Biscoff-forward, then coffee. Middle sips: blended concentrate carries the crushed Biscoff inside the drink for spice + a subtle cookie-crumb thickness. Finish: whipped topping + second Biscoff crumble adds visual dessert-drink identity. Not chalky, not clumpy — the whey dissolves into the hot concentrate before ice + milk go in. Should read as an iced-latte-crossed-with-Biscoff, not as a protein shake with a cookie in it.

BLEND INTO CONCENTRATE

ASSEMBLY

FINISH (post-pour)

Method

  1. 1
    CRUSH FIRST BISCOFF

    Crush 1 Biscoff cookie into the bottom of a tall blending cup. This cookie goes INSIDE the concentrate for spice depth throughout the drink; the second cookie stays whole for the garnish at the end.

  2. 2
    ADD COFFEE + WHEY + SWEETENER

    1/2 tbsp instant coffee, 1/2 serving unflavored whey isolate, and 2 tsp monk fruit sweetener into the blending cup with the crushed Biscoff.

  3. 3
    ADD HOT WATER

    2 tbsp hot (NOT boiling) water. Start with 2 tbsp; add the third only if the concentrate needs help moving. Hot water pulls flavor from the crushed Biscoff and dissolves the coffee faster than cold; not-quite-boiling protects the whey from denaturing.

  4. 4
    BLEND SMOOTH

    Submerge the immersion-blender head BEFORE turning it on (splatter control). Blend until the concentrate is smooth with zero visible protein clumps or Biscoff chunks. This is the Proffee-series technique differentiator — whey dissolves into the hot concentrate NOW, not into cold milk later.

  5. 5

    RIM THE SERVING GLASS (recommended): Spread 1 tsp cookie butter around the rim of the SERVING glass while it's still empty — much cleaner than rimming a full drink. The filmed video builds the entire drink in one cup, which works but is harder to keep tidy. If following the video's one-cup method, rim carefully with the drink already in place.

  6. 6
    ADD ICE + MILK

    Fill the rimmed serving glass with ice. Pour the concentrate over the ice, then add 1/2 cup Fairlife fat-free ultra-filtered milk. Fat-free is the macro-honesty pick — 2% pushes calories without adding protein.

  7. 7
    TOP WITH WHIPPED TOPPING

    Add 1 tbsp sugar-free whipped topping in a swirl over the drink.

  8. 8
    GARNISH + SERVE

    Crush the second Biscoff cookie over the whipped topping. Serve immediately — the whipped topping softens against the cold drink after 1-2 minutes.

Adult plate | Kid plate

Adult plate

Adult

Full recipe as written — 1 glass per adult at 210 cal / 22g protein. Adult-only because of caffeine.

Kid plate

Kid

Adult-only Powerup — this contains caffeine and is NOT a kid drink. Younger kids shouldn't have caffeine at all; older kids should get caffeine-free protein alternatives.

Three keys to success

  1. 1Blend whey into the HOT concentrate before adding ice or milk — Proffee-series spine, carries from Ep 1.
  2. 2Use hot but NOT boiling water. Boiling denatures whey and creates chalky texture. 2 tbsp is the target; add up to 1 more only if the concentrate isn't moving.
  3. 3Submerge the immersion-blender head BEFORE turning it on. Splatter control.

Watch the full cook

Brands I use

Biscoff Cookies (Lotus)
Original Caramelised Cookies — 2 cookies per glass
The signature spiced-caramelized cookie identity. One crushes INTO the concentrate for spice depth, one stays as the final crumble garnish. Lotus is the reference brand but any speculoos-style cookie works. Not sponsored, not endorsed, not affiliated.
Cookie Butter Spread
Trader Joe's Speculoos Cookie Butter OR Lotus Biscoff Spread (1 tsp per glass, rim)
Speculoos-style cookie butter — the rim carrier. Thin/spreadable consistency works better than thick. Both brands are widely available; use whichever you can find locally. Not sponsored.
Fairlife
Fairlife
Fat-Free Ultra-Filtered Milk (1/2 cup per glass)
Series-standard high-protein milk in the fat-free grade — same as Ep 1. 8g protein per 1/2 cup vs 4g in regular skim milk. Not sponsored.
Unflavored Whey Isolate
Any clean-tasting unflavored whey isolate — ~28g protein per serving
Protein spine. Isolate (not concentrate) blends smoother. 1/2 serving per glass = ~14g whey protein + ~8g from the fat-free ultra-filtered milk = ~22g total.
Any Instant Coffee
Nescafé, Folgers, Trader Joe's Instant, etc. (1/2 tbsp per glass)
Caffeine spine. Any instant coffee blends into the concentrate without a coffeemaker step. Caffeine content varies by brand.
Sugar-Free Whipped Topping
Reddi-wip Zero Sugar OR Truwhip Zero (1 tbsp per glass)
The visual dessert-drink identity. Any sugar-free whipped topping works. Skip if soy-allergen sensitive — the allergen list assumes standard formulations.
