If you love the deep caramelized flavor of Biscoff cookies, this Biscoff Buttercream Frosting Recipe might become your new go-to frosting. It’s silky, pipeable, and perfectly balanced—sweet but not cloying, with a warm cookie-butter flavor that pairs beautifully with vanilla, chocolate, or spice cakes.
What makes this buttercream special is its stable texture and smooth finish, even for beginner bakers working with simple tools like a hand mixer or whisk. The secret? Creaming the butter longer than usual before adding Biscoff spread. That small step creates a frosting that’s fluffy, light, and easy to spread.
Pro tip: Slightly warming the Biscoff spread (just until pourable) helps it blend seamlessly into the buttercream without creating grainy pockets.
Why This Recipe Works
Buttercream may seem simple—just butter and sugar—but small technique changes make a huge difference in texture and stability.
1. Proper butter aeration creates a fluffy frosting
Butter holds tiny air pockets when beaten. Creaming the butter for 3–4 minutes before adding sugar creates a lighter buttercream that spreads and pipes easily.
2. Biscoff spread acts like a flavor-rich fat
Biscoff cookie butter contains oils from crushed biscuits. When blended with butter, it enhances richness while adding subtle caramel spice notes. However, too much can make frosting soft—this recipe balances the ratio for stability.
3. Powdered sugar controls structure
Powdered sugar doesn’t just sweeten; it stabilizes the frosting. Its cornstarch content absorbs moisture, helping the buttercream hold shape for piping.
Did you know? Buttercream texture depends heavily on butter temperature. Butter that’s too cold won’t whip properly, while overly soft butter leads to greasy frosting.

Step-by-Step Instructions
Step 1: Soften and Cream the Butter
Beat 226 g butter in a mixing bowl for 3–4 minutes on medium speed until pale and fluffy.
Visual cue: Butter should lighten in color and look creamy with soft peaks.
Avoid this: If butter looks greasy or shiny, it’s too warm. Chill the bowl for 10 minutes before continuing.
Step 2: Add the Biscoff Spread
Add 180 g Biscoff spread and mix on medium speed for 1–2 minutes until fully combined.
Visual cue: Mixture should look smooth and glossy without streaks.
Checkpoint: Scrape the bowl halfway through mixing.
Step 3: Incorporate Powdered Sugar
Add 360 g powdered sugar gradually in 3 additions, mixing on low speed.
After each addition, mix for 30–40 seconds until incorporated.
Visual cue: Frosting will thicken and hold soft ridges when lifted with a spatula.
Step 4: Adjust Texture
Add 2–3 tablespoons heavy cream, 1 tsp vanilla, and ¼ tsp salt.
Beat on medium-high speed for 1–2 minutes.
Visual cue: Frosting should be smooth and fluffy, forming soft peaks that hold their shape.
Step 5: Final Texture Check
Lift the whisk attachment.
Perfect texture: Frosting forms peaks that gently fold over like a hook.
Too thick: Add 1 tsp cream at a time.
Too soft: Add 1–2 tbsp powdered sugar.
Troubleshooting: Common Problems
Problem: Buttercream looks grainy
Likely causes: Cold butter or unmixed sugar.
Fix next time: Beat butter longer before adding sugar.
Problem: Frosting too soft for piping
Likely causes: Warm butter or excess Biscoff.
Fix: Chill frosting 15 minutes before piping.
Problem: Frosting too sweet
Likely causes: Too much powdered sugar.
Fix next time: Increase salt slightly or add 1 tbsp cream cheese.
Problem: Buttercream separates
Likely causes: Ingredients at different temperatures.
Fix: Beat longer to re-emulsify.
Problem: Greasy texture
Likely causes: Butter too warm.
Fix: Refrigerate bowl 10 minutes and re-whip.

FAQs
Can I replace Biscoff spread with peanut butter?
Yes, but the flavor changes completely. Use creamy peanut butter and reduce cream slightly since peanut butter is softer.
How do I make buttercream less sweet?
Add a pinch more salt or replace ¼ cup sugar with cream cheese.
Can I double the recipe?
Absolutely. Keep mixing time slightly longer (about 1–2 extra minutes) to fully aerate the butter.
Why is my buttercream melting on the cake?
Your kitchen may be warm. Chill the frosting or cake layers briefly before decorating.
Can I make this in an OTG oven kitchen setup?
Yes—since it’s a frosting, no oven is required. Just ensure butter stays around room temperature (20–22°C / 68–72°F).
Notes From My Kitchen (Testing Log)
Batch 1:
Used equal parts butter and Biscoff. Result: frosting tasted great but too soft for piping.
Batch 2:
Reduced Biscoff slightly and increased powdered sugar. Texture improved but became overly sweet.
Batch 3:
Added a pinch of salt and whipped butter longer before adding ingredients. Texture became noticeably lighter.
Batch 4:
Tested adding slightly warmed Biscoff spread. It blended faster and eliminated small lumps.
Final Version:
Chosen ratio balances flavor, stability, and pipeability. The frosting holds shape for cupcakes and spreads smoothly on layer cakes.
