A Smarter Way to Offer Vegan Cupcakes.

 

Petley Grain provides a microwave-based cupcake system for bakeries that want to offer vegan and gluten-free options without dedicating oven space, additional labor, or inventory to specialty batches.

 

Using shelf-stable dry mixes and simple preparation steps, bakeries can produce fresh, large cupcakes in minutes, frost them as usual, and sell with confidence — while avoiding overproduction and unsold vegan product.

 

Petley Grain recipes are designed specifically for silicone cake molds, standard commercial microwaves, and real-world staff workflows. Clear instructions, predictable timing ranges, and forgiving formulations make training simple and results consistent across shifts and locations.



Why Bake Vegan Cupcakes On Demand?

 

Vegan cupcakes are one of the hardest bakery items to batch correctly. Demand is unpredictable, shelf life is shorter, and unsold product often ends up as waste.

 

Petley Grain’s bake-on-demand system removes the guesswork.

 

Instead of committing oven time and inventory to specialty batches, bakeries can prepare vegan cupcakes only when they’re ordered. This reduces spoilage, frees up oven capacity, and keeps vegan options available at all times — without risk.

 

What changes operationally

 

  • No forecasting vegan demand
  • No end-of-day waste
  • No pressure to “sell through” specialty items
  • No oven scheduling conflicts

 

What stays the same

 

  • Large, bakery-style cupcakes
  • Standard frosting and decoration
  • Existing staff workflows
  • Consistent quality customers recognize

 

Bake-on-demand turns vegan cupcakes from a liability into a controlled, profitable menu item.

 


How the System Works


Petley Grain’s cupcake system is designed to fit seamlessly into existing bakery operations. There’s no new equipment to learn and no change to how cupcakes are finished or sold.


Step 1 — Mix

 

Combine Petley Grain dry mix with a small set of additional ingredients (liquid and flavor components) to create the batter.

 

Step 2 — Microwave


Transfer batter into large silicone cupcake molds and microwave using standard commercial or back-of-house microwaves.

Clear timing ranges are provided to account for microwave power differences.


Step 3 — Frost & Sell


Allow the cupcake to cool briefly, then frost and decorate as usual. Cupcakes can be sold immediately or placed in the display case.

 

No oven time.

No batch baking.

No specialty training required.

 

Why this matters


  • Production happens only when needed
  • Staff can be trained quickly
  • Results remain consistent across shifts
  • Vegan cupcakes integrate cleanly with existing menus

 

Designed for Large Cupcakes


Petley Grain recipes are formulated specifically for large, bakery-style cupcakes, not mugs or novelty formats.

 

The system is designed to work with silicone cupcake molds that produce a familiar cupcake shape with clean sides, stable structure, and a frosting-ready top.

 

This allows bakeries to:

 

  • Maintain their existing cupcake presentation
  • Frost and decorate without adjustment
  • Display vegan cupcakes alongside traditional offerings
  • Meet customer expectations for size and quality

 

Why silicone molds


Silicone cupcake molds provide consistent portioning, reliable release, and even microwave heating — all critical for large-format cupcakes produced on demand.

 

Petley Grain formulations account for:

 

  • Moisture retention in gluten-free baking
  • Structure needed for frosting and handling
  • Clean release with light oiling


The result is a cupcake that looks, handles, and sells like a bakery cupcake — not a microwave substitute.

 


Available Cake Options


Petley Grain offers multiple vegan cake styles built on a shared, easy-to-use system. Bakeries can choose the options that best fit their menu and customer base without increasing operational complexity.

Looks Like a Cupcake. Sells Like a Cupcake.

 These aren’t mug cakes or substitutes.

They’re full-size cupcakes with real bakery presence — just made fresh on demand.

 

Microwave-Only by Design


These cakes are engineered specifically for microwave ovens.

They are not adapted from traditional baked recipes and are not intended for conventional ovens.

The structure, moisture, and rise depend on microwave heating, where rapid internal steam sets the cake quickly and evenly. Without eggs or egg substitutes, this process delivers a soft, consistent crumb in minutes.

Using an oven will not produce the intended texture or results.


 

Who This Is For


Petley Grain’s microwave cupcake system is designed for bakeries that want to offer vegan and gluten-free options without adding complexity to their operation.


A good fit for:


  • Cupcake bakeries offering vegan options alongside traditional flavors
  • Smallcakes-style operators with high daily volume and limited oven flexibility
  • Franchised bakeries that need consistency across locations
  • Bakeries reducing waste from specialty or low-demand items
  • Shops expanding dietary offerings without retraining staff

 

Especially useful when:


  • Vegan demand is inconsistent or unpredictable
  • Oven time is already at capacity
  • Specialty batches lead to end-of-day waste
  • Staff turnover makes complex processes risky
