Black & Decker 12-Speed Blender Review
Why I reached for this blender
I put this Black & Decker blender through the same paces I use to judge any everyday kitchen workhorse: weekday smoothies with frozen fruit, quick sauces and pestos for dinner, and the occasional round of ice for weekend drinks. Over a couple of weeks, I leaned on its 12 speeds and pulse function, filled and refilled the 6‑cup glass jar, and ran enough cycles to get a feel for its strengths and limits. It’s an approachable, budget‑friendly machine with a classic design and a few thoughtful touches that make it easy to live with.
Build and design
The glass jar is the star of the show. At 6 cups, it’s generous for family smoothies and soups, and the material choice matters: glass doesn’t hold onto odors or stain the way some plastics do. The jar’s easy‑pour spout works as advertised—I got clean pours into narrow pint glasses with minimal drips.
The base is plastic with chrome accents. It’s light in hand, but once the jar is seated and filled, the whole setup feels planted and stable on the counter. The 4‑point stainless steel blade seats securely into the jar’s collar and inspires confidence—no play, no rattling. I appreciate the straightforward interface: clearly marked buttons for 12 speeds plus a dedicated pulse. It’s the kind of layout that invites you to just start blending without hunting for the “right mode.”
Footprint matters in real kitchens. This unit is low‑profile enough to slide under my upper cabinets, and it doesn’t hog counter space. At just over 12 pounds, it’s not featherlight, but that heft helps keep it from skittering around when you’re blending dense mixtures.
Controls and everyday usability
Twelve speeds is more than most people will use daily, but the spread is genuinely useful. I gravitated to the lower third for chopping and stirring (think salsa, pico, or a breadcrumb grind), the middle speeds for dressings and pesto, and the higher settings for smoothies and purees. Pulse is responsive and easy to feather, which is key for controlled chopping.
There’s no dedicated tamper, so technique matters with thicker blends. Starting low and stepping up as a vortex forms works well. If I overloaded it with frozen fruit and minimal liquid, the mixture stalled; pausing to add a splash of liquid or to redistribute contents solved it. That’s typical at this price point and not a dealbreaker—you just need to pack and portion thoughtfully.
Performance tests
- Smoothies and frozen blends: With a base of milk or juice and a reasonable ratio of frozen fruit to liquid, the blender produced smooth, drinkable results in 30–45 seconds at mid‑high speeds. Leafy greens were fully incorporated with an extra 10–15 seconds. For ultra‑thick smoothie bowls, it asked for more liquid than a high‑power machine would, but that’s expected; it’s designed for drinking‑consistency blends, which it nails. 
- Ice crushing: The 4‑point stainless blade does fine with ice. Using pulse to chop and then stepping up to a higher speed yielded a coarse to medium snow suitable for margaritas. It handles a tray’s worth of cubes without drama if you add a bit of liquid. Running dry ice for extended periods isn’t wise with any blender; brief pulses are the way to go here. 
- Sauces and prep: Pesto came out bright and evenly textured using mid speeds and pulse. I liked that I could keep it rustic by stopping early or take it finer with another 5–10 seconds. Salsa and chimichurri also benefited from the precise pulse control. For nut‑heavy spreads or thick hummus with minimal liquid, I had better results working in stages and scraping down once—a normal workflow for this class of blender. 
- Soups and purees: Warm vegetable soups (cooled slightly before blending) ended silky enough for weeknight dinners. It doesn’t achieve the velvety gloss of a high‑end machine, but for an everyday blender, the texture was satisfying with no fibrous bits. 
Noise and stability
At full tilt, it’s loud—about what I expect from a mid‑range countertop blender. The sound is a steady whir rather than a harsh screech. More importantly, it stays put. Even with dense loads, I didn’t have to chase it across the counter. The glass jar’s mass helps here, and the base doesn’t transmit distracting vibrations.
Cleaning and maintenance
Cleanup is refreshingly easy. The removable parts are dishwasher‑safe, and after messy jobs (pesto, smoothies), I typically did a quick pre‑rinse and then let the dishwasher finish the job. For handwashing, a drop of soap and warm water blended on low for 10 seconds clears residue under the blade, followed by a rinse. The jar’s wide opening makes it easy to reach in with a sponge if needed. After multiple cycles, the glass still looks clear with no fogging, and the blade shows no signs of corrosion.
As with any blender that disassembles, take a beat to re‑seat the gasket and blade assembly correctly. It’s straightforward, but that extra second prevents leaks later.
Capacity and footprint
A 6‑cup capacity hits a practical sweet spot. It’s large enough for two tall smoothies or a batch of soup without awkward half‑fills. The low‑profile design tucks under standard cabinets, and the corded base doesn’t dominate the counter. If you’re tight on space, this is an easy appliance to leave out without it taking over.
Durability and warranty
After repeated ice and frozen fruit runs, the blade remained sharp, and the coupling showed no unusual wear. The base casing doesn’t feel premium, but the overall unit feels sturdier than many in its price tier. A 2‑year limited warranty adds a layer of reassurance; if you’re outfitting a kitchen on a budget, that coverage matters.
What I like
- Glass jar with an effective pour spout that minimizes drips
- Versatile 12‑speed range plus a crisp, useful pulse function
- Reliable performance for smoothies, sauces, and ice with proper technique
- Dishwasher‑safe parts make cleanup almost effortless
- Stable in use despite a lighter plastic base
- Sensible size that fits under cabinets and serves families well
What could be better
- No tamper; very thick blends require more liquid or pauses to redistribute
- Top‑speed noise is typical for the category—expect to raise your voice
- The 12‑button layout is simple, but the abundance of speeds won’t matter to everyone
- Not a replacement for high‑power machines on ultra‑dense tasks (nut butters, thick smoothie bowls without added liquid)
Who it’s for
If you want an everyday blender that handles the staples—morning smoothies, purees, pesto, salsa, crushed ice—without fuss, this is a strong, sensible choice. The glass jar and dishwasher‑safe components make it easy to live with, and the control it offers at lower speeds is a highlight for cooks who like to fine‑tune their textures. Power users chasing bar‑quality, super‑thick frozen blends with minimal liquid may hit the limits, but for most households, it delivers consistent results with minimal learning curve.
Recommendation
I recommend this Black & Decker blender for budget‑minded cooks who value a glass jar, straightforward controls, and dependable performance on everyday tasks. It excels at drinkable smoothies, sauces, and general prep, and it crushes ice well when you use pulse and a splash of liquid. If your routine leans on ultra‑thick blends or nut butters, you’ll want a higher‑powered machine with a tamper. For everyone else, this is an easy appliance to put to work daily—and to clean up just as quickly.

Serve in cups or as take-home pints. Promote flavor transparency and zero additives; clean quickly between batches with the dishwasher-safe components.
Creative
Galaxy Smoothie Art
Use the 12 speed settings to build silky fruit layers (low for thick bases, mid for pourable layers) and the pulse function to swirl in contrasting colors for nebula-like patterns. Pour via the easy-spout into bowls or glasses to paint stars with yogurt dots and chia 'constellations'. The dishwasher-safe jar makes color changes quick between layers.
Crunchy-to-Creamy Nut Butter Flight
Roast almonds/peanuts, then pulse for a rustic, crunchy spread. Increase speeds gradually to achieve medium and ultra-smooth textures. Create a 3-texture tasting flight flavored with cinnamon, cocoa, or maple. The 4-point stainless steel blade handles nuts well; finish with a drizzle blended at low speed for glossy sheen.
Pesto Palette (5 Herb Variations)
Blend basil, parsley, cilantro, arugula, and mint pestos, adjusting speeds to control oil emulsification and leaf texture. Use pulse for chunky rustic styles and high speed for velvety emulsions. Serve as a painter’s palette with bread and veggies; the dishwasher-safe parts make switching flavors mess-free.
Instant Fruit Sorbet Tiles
Crush frozen fruit with the ice-capable blade, adding a splash of juice at medium speed until it forms a scoopable sorbet. Spread into silicone molds or thin sheets and freeze to create ‘tiles’ for plating desserts. Pulse in mix-ins like chocolate shards or toasted coconut for texture contrasts.
Citrus Sugar and Spiced Salt Finishes
Dry citrus zest and pulse with sugar for vibrant finishing sugar; do the same with flaky salt and toasted spices for savory rims and rubs. Short pulses prevent over-powdering; switch to low speed to aerate and evenly distribute aromatics. Store in jars with labels for a colorful pantry display.
