Easy Fixes for How to Thicken Frosting Without Powdered Sugar

When your frosting isn’t cooperating, you might feel tempted to start over or compromise on its appearance.

But with a few simple adjustments, you can thicken frosting easily without using powdered sugar.

Here are some tried-and-true methods to fix runny frosting and achieve that ideal consistency.

Add Cornstarch

Cornstarch is a great thickening agent and can be used in small amounts to firm up frosting.

Start by adding one teaspoon at a time, blending thoroughly after each addition to avoid lumps.

The cornstarch will stabilize your frosting without altering its flavor significantly.

Incorporate Cream Cheese

Cream cheese is another excellent option, especially for frostings that pair well with a tangy twist.

Simply blend softened cream cheese into your frosting a little at a time until it reaches the desired thickness.

Be mindful of the flavor profile—this works best with frostings for cakes like carrot or red velvet.

Use Cocoa Powder

If you’re making chocolate frosting, cocoa powder can serve as both a flavor enhancer and a thickener.

Add small amounts gradually, mixing as you go to prevent a chalky texture.

This option is perfect for intensifying the chocolate flavor while fixing your frosting.

Add Flour

For frostings that don’t rely on sweetness alone, flour can work wonders.

Heat a tablespoon of flour with a small amount of milk on the stove until it thickens, then let it cool completely.

Fold the mixture into your frosting to give it more body without adding sweetness.

Try Gelatin

Gelatin can work as a stabilizer, particularly for whipped frostings.

Dissolve unflavored gelatin in a small amount of warm water and let it cool slightly before blending it into your frosting.

This method works best if you’re after a firmer, more sculptural frosting.

Adjust the Temperature

Sometimes, all your frosting needs is a quick trip to the fridge.

Cooling the frosting can help firm it up, especially for butter-based varieties.

Let it chill for 15–30 minutes and then re-whip it to restore its texture.

Mix in Nut Butters

Nut butters, like almond or peanut butter, are excellent for adding both flavor and thickness.

These work best for unique dessert themes and add a creamy texture to your frosting.

Be sure to add them in small amounts to maintain control over the taste.

Blend in Mashed Potatoes

While unconventional, mashed potatoes (yes, really!) can create a thick and creamy texture for frosting.

Use plain, unsalted mashed potatoes, and incorporate them gradually into your frosting.

This technique works well for frosting that pairs with savory or unique dessert flavors.

Use Room Temperature Ingredients

Ensure all your ingredients are at the same temperature to avoid separation or inconsistent textures.

Measure Precisely

Accurate measurements can make all the difference in achieving the perfect frosting consistency.

Mix Gradually

Overmixing can lead to a runny texture, especially for whipped frostings. Mix just until combined for best results.
