🫙 What "Shelf-Stable" Means in MN Law
Shelf-Stable Foods Under Minnesota Cottage Food Law
Minnesota's cottage food law (Minn. Stat. 28A.152) is built around a single organizing principle: the food must be non-potentially hazardous (NPH). In practical terms, this means the food must be safe to store and sell at room temperature without risk of dangerous bacterial growth. Most shelf-stable products — foods that don't need refrigeration to be safe — qualify. This page breaks down each major shelf-stable category in depth, including recipes, testing, packaging, and shelf life guidance.
✓ Minnesota is shelf-stable friendly. The state allows baked goods, jams, jellies, properly acidified pickles, candy, dry mixes, granola, and many other products — making it one of the more accessible cottage food states for home bakers and food entrepreneurs.

Baked Goods — Deep Dive
Baked goods are the most common cottage food product in Minnesota. The rule: they must be shelf-stable, meaning they don't require refrigeration for food safety. This covers an enormous range of products.
Breads & Quick Breads
Yeast breads, sourdough, banana bread, zucchini bread, cornbread, focaccia
✓ Allowed
Allowed Varieties
- ✓White, wheat, multigrain sandwich loaves
- ✓Sourdough (including with add-ins)
- ✓Banana bread, zucchini bread, pumpkin bread
- ✓Cornbread (shelf-stable, not custard-style)
- ✓Focaccia, flatbreads, pita
- ✓Cinnamon swirl loaves
- ✓Dinner rolls and buns
Not Allowed
- ✕Breads with fresh meat or cheese fillings
- ✕Breads requiring refrigeration after baking
- ✕Filled breads with cream cheese center
Shelf life tip: Most standard breads are shelf-stable for 3–5 days at room temperature, up to a week in an airtight container. Sourdough keeps longer due to natural acidity. Clearly label the production date as required by Minnesota law — buyers use this to assess freshness.
Cakes & Cupcakes
Layer cakes, sheet cakes, cupcakes — with shelf-stable frosting only
✓ Allowed
Allowed Frostings & Toppings
- ✓Royal icing (egg white powder + sugar)
- ✓American buttercream (butter + powdered sugar — shelf-stable)
- ✓Fondant and modeling chocolate
- ✓Ganache (high-chocolate, shelf-stable)
- ✓Glazes and poured sugar icing
- ✓Shelf-stable meringue-based frosting
Prohibited Frostings
- ✕Cream cheese frosting (requires refrigeration)
- ✕Fresh whipped cream topping
- ✕Custard or pastry cream filling
- ✕Mascarpone or fresh ricotta filling
- ✕Fresh fruit or yogurt layers
Frosting rule of thumb: If the finished cake with frosting can sit safely at room temperature for 2+ days without refrigeration, it's likely shelf-stable. If your recipe card says "refrigerate after frosting," it's not allowed under cottage food. American buttercream (butter + powdered sugar, no fresh dairy) is borderline — it is generally considered shelf-stable for 1–2 days but confirm with your specific recipe.
Pies & Pastries
Fruit pies, nut pies, hand pies, turnovers — fruit and nut fillings only
✓ Allowed
Allowed
- ✓Apple, cherry, blueberry pie
- ✓Pecan pie, walnut pie
- ✓Pineapple upside-down cake
- ✓Fruit-filled hand pies and turnovers
- ✓Pop-Tart style pastries (fruit-filled)
- ✓Empanadas with shelf-stable fillings
Not Allowed
- ✕Cream pies (banana cream, coconut cream)
- ✕Custard pie (including pumpkin pie — requires refrigeration)
- ✕Chess pie if custard-based
- ✕Key lime pie
- ✕Lemon meringue pie (lemon curd requires refrigeration)
⚠️ Pumpkin pie debate: Traditional pumpkin pie contains eggs and dairy and requires refrigeration — it is NOT allowed as a cottage food in Minnesota. Pumpkin bread (no eggs/dairy concern, baked through) is fine. When in doubt, check with MDA.
Cookies, Bars & Brownies
The most flexible and easiest-to-sell cottage food category
✓ Allowed
Allowed
- ✓Chocolate chip, oatmeal raisin, sugar cookies
- ✓Snickerdoodles, gingersnaps, shortbread
- ✓Brownies and blondies
- ✓Lemon bars (if shelf-stable — check recipe)
- ✓Rice krispie treats
- ✓Meringue cookies
- ✓Biscotti
- ✓Macarons (French — shelf-stable ganache or jam filling)
Watch Out For
- ⚠Lemon bars with fresh lemon curd filling — test or use shelf-stable recipe
- ⚠Macarons with fresh cream cheese filling — use shelf-stable filling
- ⚠Cookie sandwiches with dairy-based creams
- ✕Filled cookies requiring refrigeration
🍯 Category 2
Jams, Jellies & Preserves — Deep Dive
Jams and preserves are the second most popular cottage food category in Minnesota. They require pH ≤ 4.6 and must be made using tested, approved recipes unless you have laboratory verification.
Jams, Jellies, Marmalades & Fruit Butters
Properly acidified fruit spreads — the backbone of many Minnesota cottage food businesses
✓ Allowed
Allowed Products
- ✓Strawberry, raspberry, blueberry jam
- ✓Grape, crabapple, apple jelly
- ✓Orange, lemon marmalade
- ✓Peach, apricot preserves
- ✓Apple butter (properly acidified)
- ✓Pumpkin butter — if pH ≤ 4.6 (test required)
- ✓Fig jam (usually high-acid)
- ✓Hot pepper jelly (properly acidified)
Critical Rules
- ⚠Always use a research-tested recipe
- ⚠Test pH 24 hours after processing
- ⚠Modified recipes require lab testing
- ⚠Do not reduce sugar or acid in a tested recipe
- ✕Low-sugar or sugar-free jams — verify pH before selling
- ✕Savory jams with low-acid vegetables as primary ingredient
Minnesota tomato note: The University of Minnesota Extension publishes a specific Minnesota Tomato Mixture recipe designed to safely acidify tomatoes for canning. Tomatoes sit right at the pH 4.6 boundary — always use the MN-tested recipe and add the specified amount of lemon juice or citric acid.

🥒 Category 3
Pickles & Home-Canned Goods — Deep Dive
Home-canned goods have the most specific rules of any cottage food category in Minnesota. They are allowed, but with strict pH and geographic restrictions.
Home-Canned Pickles, Vegetables & Fruit
Allowed in Minnesota only, pH ≤ 4.6, must be home-processed and home-canned in Minnesota
⚠ Conditions Apply
Requirements
- ⚠pH must be ≤ 4.6 (tested or proven recipe)
- ⚠Must be home-processed AND home-canned in Minnesota
- ⚠May only be sold inside Minnesota (never shipped out of state)
- ✓Dill pickles (vinegar-brined)
- ✓Bread & butter pickles
- ✓Pickled beets
- ✓Pickled peppers (properly acidified)

📦 Packaging
Packaging Your Shelf-Stable Products
Minnesota's cottage food law doesn't prescribe specific packaging formats, but packaging directly affects your product's shelf life, label compliance, and professionalism at market. Here are the best options by product type.
Glass Jars
Ideal for jams, jellies, pickles, and honey. Canning jars with sealed lids maintain freshness and signal quality. Required for home-canned goods.
Best for: Jams & Pickles
Bakery Boxes
Kraft or white bakery boxes with windows for cakes, cupcakes, cookies, and pastries. Professional presentation, easy labeling surface.
Best for: Baked Goods
Cellophane Bags
Clear heat-sealed bags for cookies, brownies, dry mixes, granola, and candy. Low cost, allows product visibility, easy to label.
Best for: Cookies & Candy
Tin Canisters
Metal tins work well for cookies, brittle, popcorn, and loose granola. Premium feel; excellent for gift items. Harder to print labels — use adhesive label.
Good for: Gifts & Snacks
Kraft Paper Wrap
Butcher paper or parchment-wrapped breads and pastries. Eco-friendly and artisanal feel. Shorter shelf life due to breathability — best for day-of sales.
Varies by Product
Stand-Up Pouches
Resealable mylar or kraft pouches for granola, trail mix, dry mixes, and spice blends. Professional look with excellent shelf life if heat-sealed.
Best for: Dry Mixes
ℹ️ Whatever packaging you choose, your label must be legible and contain all required information. Labels applied with adhesive paper are fine — they don't need to be printed directly on the packaging. A handwritten label is technically allowed but professional printed labels build buyer confidence.
⏱️ Shelf Life
Estimated Shelf Life by Product Type
Minnesota requires the production date on every label — not a "best by" date (though you may add one voluntarily). Here are general shelf life estimates to guide your production planning and customer communication.

| Granola (sealed pouch) | 3–6 months | Airtight, away from heat | Medium |
| Cookies & biscotti | 2–4 weeks (airtight) | Room temperature, airtight | Medium |
| Brownies & bars | 1–2 weeks (airtight) | Room temperature, airtight | Medium |
| Cakes & cupcakes (frosted) | 3–5 days at room temp | Airtight container or box | Short |

| Quick breads (banana, zucchini) | 4–7 days | Wrapped, room temperature | Short |
📚 Recipe Sources
Where to Find Approved, Tested Recipes
For all acidified, canned, or fermented products, use research-tested recipes from trusted sources. Modifying a tested recipe — especially reducing sugar, vinegar, or changing ratios — may push your product above pH 4.6 and make it unsafe and illegal to sell.
