Delicious Sweet Potato Mango Frosting Recipe

A creamy, protein-packed frosting made from sweet potatoes and mango — and nobody will ever guess.

I created this frosting to treat my mom while also sneaking in her protein and fiber goals. Because that's love language, right? Sweet potatoes blended with mango puree, vanilla, monkfruit, and plant protein powder until completely silky smooth. It pipes beautifully, tastes indulgent, and has about 10g of protein per serving. This is the kind of frosting that makes people ask for the recipe before they've even finished the cupcake.

I used Deep Impact Mango Vanilla plant protein for this one — but any mango or vanilla plant protein works. The sweet potato does most of the heavy lifting in terms of texture and creaminess, so the protein powder is really just there for the macros and a little flavor boost.

Why This Recipe Works

Sweet potato is naturally creamy, sweet, and full of fiber. Mango puree adds a tropical brightness that lifts the whole flavor. Plus, plant protein powder gives you 10g of protein per serving without changing the taste. And monkfruit? It offers zero-calorie sweetness with no aftertaste.

How to Make Sweet Potato Mango Frosting (Overview)

This comes together in three simple steps:

1. Cook & Cool

Cook sweet potatoes until completely soft. Make sure to cool them fully before blending — warm sweet potato will make the frosting too loose.

2. Blend

Blend all ingredients together until completely silky smooth. Taste and adjust sweetener if needed.

3. Chill & Use

Refrigerate until firm, then frost your cupcakes and finish with mango nut butter or fresh mango chunks.

Tips for Best Results

• Cook sweet potatoes until very soft — the smoother they are, the silkier your frosting.

• Cool completely before blending — don't rush this step!

• Chill the frosting before piping for a cleaner, firmer finish.

• Drizzle mango nut butter on top to take it to another level.

• This frosting also works as a dip, spread, or smoothie bowl topping.
