Quick Answer: The most reliable homemade bird seed recipe is Audubon’s no-melt suet cake — shortening, nut butter, wild bird seed, oats, and corn meal, frozen in an ice cube tray — but it’s a cold-weather-only recipe, since Audubon itself says it’s “not recommended for outdoor temperatures above 50 degrees.” For a cheaper everyday seed mix, buy bulk black-oil sunflower (the Cornell Lab of Ornithology’s top all-around pick) and blend in your own millet or cracked corn instead of paying for a pre-made bag. For a warm-weather-friendlier option, gelatin or agar-based seed ornaments work as a cool-season craft, not a summer feeder.
Making your own bird seed and suet is one of the cheapest ways to keep a feeder full, and it’s a project you can do with ingredients already in the kitchen. It’s not a full replacement for a bulk bag once you’re feeding several feeders through a season, but for a first batch, a gift project, or a cold-weather suet swap, these three recipes actually work.
Homemade bird seed, by the numbers
- 59 million Americans feed wild birds, spending roughly $4 billion a year on bird seed, according to the U.S. Fish and Wildlife Service — a habit that often starts with exactly the kind of low-cost, homemade batch covered here.
- Above 50°F, Audubon says its own no-melt suet recipe is “not recommended” — the shortening-based fat can soften and smear outdoors, so treat any homemade suet or gelatin ornament as a cold-weather project.
- Black-oil sunflower is the Cornell Lab of Ornithology’s pick for “best all-around seed” — it’s the single ingredient worth buying in bulk if you’re blending your own mix instead of paying for a pre-made bag.

1. No-melt suet cake (Audubon’s recipe)
This is Audubon’s own published recipe, and it’s the closest homemade equivalent to a store-bought suet cake.
What you need
- Mix the wild bird seed, oats, and corn meal together in a bowl and set aside.
- Melt the shortening and nut butter together in a separate pot, stirring until fully combined.
- Pour the melted mixture into the dry ingredients and stir until evenly coated.
- Spoon into an ice cube tray and freeze for one to two hours before loading into a suet feeder.
- Per Audubon, this recipe is "not recommended for outdoor temperatures above 50 degrees" — keep it for late fall through winter.
Batching up a season’s worth of suet before the cold sets in? Try Kindle Unlimited free for field guides and backyard-birding how-tos while your homemade cakes firm up in the freezer. Skip bacon grease entirely in any suet recipe — the curing salts used to preserve bacon are unsafe for birds — and avoid butter too, since it melts fast and turns rancid outdoors. Once a batch is frozen, our best suet feeder picks add the tail-prop and squirrel-resistant cage a homemade cake needs to actually stay put.
2. DIY bulk seed mix
If “homemade” just means cheaper than a pre-made bag, this is the recipe that actually moves the needle on cost.
What you need
- Start with black-oil sunflower as the base — the Cornell Lab of Ornithology calls it the single best all-around seed, drawing cardinals, chickadees, finches, and jays.
- Add a smaller portion of white proso millet if ground-feeding species like juncos, doves, or sparrows visit your yard.
- Mix in cracked corn sparingly — it's cheap filler that some species eat, but too much dilutes the sunflower most birds actually want.
- Blending your own from bulk components sidesteps the padded filler ratios in many pre-made mixed blends, since you decide exactly what goes in.
This is less a “recipe” than a smarter shopping list — but it’s the cheapest way to feed a yard long-term. See our best bulk bird seed guide for exact bag sizes and price-per-pound comparisons if you’d rather buy a ready-mixed bulk bag than blend your own, and our best wild bird food guide for which store-bought blends already get this ratio right.
3. Gelatin seed ornaments
A fun, low-mess project for gifts or a holiday craft — just don’t expect it to hold up in summer heat.
What you need
- Dissolve unflavored gelatin in warm water with a small amount of corn syrup as a binder, then stir in birdseed until fully coated.
- Press the mixture into cookie cutters set on parchment paper, and poke a hole through each with a straw for hanging string.
- Let the ornaments dry and set for several hours before removing them from the molds.
- Standard gelatin ornaments are a cold-weather project — some recipes swap in agar powder above 50°F, since it's plant-based and holds up better in heat, but treat any version as a cool-season craft rather than a year-round feeder.
These work best as a one-off gift or kids’ activity rather than a primary feeding strategy — they hold far less seed than even a small feeder. Once the ornaments are gone, our DIY bird feeder guide covers four other no-cost projects, including a pinecone version that uses the same peanut-butter-and-seed idea without the gelatin step.
What to skip
Three things to leave out of any homemade batch. Bacon grease — the curing salts used to preserve bacon are unsafe for birds, unlike plain shortening or lard. Butter — it melts too fast and turns rancid outdoors, unlike the shortening-nut-butter combination Audubon’s recipe uses. Bread — it fills birds up with almost no nutritional value and has been linked to wing deformities in ducklings and geese when it becomes a dietary staple, so it doesn’t belong in a suet cake or seed mix either.
The bottom line
For suet, Audubon’s no-melt recipe (shortening, nut butter, seed, oats, corn meal, frozen in an ice cube tray) is the most reliable homemade option — just keep it below 50°F. For everyday feeding, blending your own mix from bulk black-oil sunflower beats a pre-made bag on price without sacrificing the seed birds actually want. And gelatin seed ornaments are a fun cold-weather gift project, not a primary feeding plan.
