MuellerLiving Ultra-Stick Immersion Hand Blender, 500W Heavy Duty Motor, 8-Speed Turbo, Whisk & Beaker Review (2026)

Why a stick blender matters for soap

Bringing cold process soap batter to trace by hand with a whisk can take a long time and tire out your arm well before the oils and lye solution fully emulsify. A stick blender like this one shortcuts that process dramatically, pulsing the mixture to trace in minutes instead of the better part of an hour, which is why an immersion blender has become close to standard equipment for cold process soap makers rather than an optional extra. The MuellerLiving Ultra-Stick brings a 500W motor to that job along with 8 speed settings and a turbo mode, giving makers more control over how aggressively the batter gets blended than a single speed stick blender would.

Power and control

A 500W motor sits on the stronger end for a handheld stick blender, which matters when working through a full batch of soap oils that can be noticeably thicker than the smoothies or soups these blenders are also marketed for. The 8-speed turbo setting lets you start slow while the oils and lye solution are still separating and step up power as the batter thickens toward trace, rather than being locked into one blending intensity the whole time. The stainless steel blending shaft and blades are built for dense mixtures, and the ergonomic grip and non-slip handle help with control during the several minutes of active blending a typical soap batch needs.

What is included

Alongside the blending shaft, this set includes a whisk attachment, a milk frother, and a measuring beaker, all of which are aimed primarily at the blender's core kitchen uses like whipping cream, frothing milk, and mixing batters. For soap making, the beaker attachment is genuinely useful for measuring and test batching small amounts of a new recipe before committing a full mold's worth of oils and lye. The whisk and frother are less relevant to soap work but do not get in the way, and the blending shaft, whisk, and frother are all listed as dishwasher safe, which simplifies cleanup after a lye-heavy session.

Things to watch for with soap batter

A powerful motor is generally a plus for soap making, but running this blender at its higher turbo speeds for the full blending process can whip excess air into the batter, leading to more surface bubbles in the finished bars than a gentler blending approach would produce. Many soap makers pulse a stick blender in short bursts rather than holding it on continuously, alternating with hand stirring, and that technique works well with this blender's range of speeds. It is also a bit heavier than the most basic single speed stick blenders on the market, which is a fair tradeoff for the stronger motor but worth knowing if you blend large batches often.

Bottom line

This is a genuinely capable stick blender for cold process soap making, with enough motor power and speed range to handle everything from a small test batch in the included beaker to a full size batch of oils. It is sold as a general purpose kitchen blender first, so the whisk and frother attachments will mostly sit unused if soap is your only reason for buying it, but that does not take away from how well the core blending shaft performs on soap batter. Makers who pulse rather than run it continuously at full speed should get smooth trace without excess air bubbles.
