Homemade Suet Recipe: How to Make Suet Cakes for Wild Birds
Homemade suet is melted fat mixed with seed, oats and cornmeal, then chilled into cakes for a suet cage. This guide pulls the shared method from Birds & Blooms, Audubon, Cornell Lab and Georgia DNR, shows where they disagree (mostly on warm-weather limits), and lists the gear that makes the job easier.

How this guide was made: research-based from the cited expert sources, compiled with AI assistance and reviewed by the editorial team. We did not hands-on test any recipe or product.
Quick answer
The simplest recipe in our sources is Birds & Blooms’ no-render cake: 1 cup peanut butter, 1 cup lard, 2 cups quick oats, 2 cups birdseed mix, 1 cup yellow cornmeal and 1 cup flour. Melt the peanut butter and lard on low heat, stir them into the dry mix, press into a mold once cool, and chill. Audubon and Cornell both stress cool weather: Audubon says its vegetarian version is not for outdoor temperatures above 50°F, and Georgia DNR says suet melts and spoils quickly above 70°F. When in doubt, make small batches, keep them cold, and bin anything moldy.

Three recipes the sources agree on
1. Peanut butter and lard cake
Birds & Blooms (December 2023): 1 cup peanut butter, 1 cup lard, 2 cups quick-cooking oats, 2 cups birdseed mix, 1 cup yellow cornmeal, 1 cup flour. Melt the peanut butter and lard on low heat, mix the dry ingredients in a large bowl, stir in the melted fat, press into molds once cool, and refrigerate. The South Carolina Wildlife Federation (January 2018) gives a close variant with whole wheat flour and optional raisins, nuts or seed.
Who it is for: beginners who want no rendering. Skip it in warm weather.
2. Vegetarian shortening cake
Audubon (modified October 2024): 1.5 cups shortening (the editors suggest palm-oil-free), 0.75 cup nut butter, 3.5 cups wild bird seed, 1 cup quick oats and 0.5 cup cornmeal. Melt the fats, pour over the dry mix, spoon into an ice cube tray and freeze 1 to 2 hours. Audubon warns it is not for outdoor temperatures above 50°F.
Who it is for: people avoiding animal fat. Skip it above 50°F.
3. Rendered kidney-fat cake
Georgia DNR says kidney and loin fat is best and that rendered fat resists spoiling and melting better than raw. Audubon (2011) suggests melting fat over moderate-low heat and straining it through cheesecloth at least twice, then using a starter ratio of 1 cup fat, 1 cup flour and 1 cup other add-ins. Georgia DNR warns that suet can catch fire if it gets too hot, so use a double boiler on low heat.
Who it is for: cooks comfortable rendering. Skip it if you dislike the smell, which can also draw squirrels and other animals (Grit, 2020).
Step by step: the no-render method
- Warm the peanut butter and lard together on low heat until melted. Do not overheat.
- Stir oats, birdseed, cornmeal and flour together in a large bowl.
- Pour the melted fat over the dry mix and stir until evenly coated.
- Let it cool until it can be pressed, then pack into molds, an ice cube tray or a lined pan.
- Refrigerate or freeze until solid. Audubon freezes small cakes for 1 to 2 hours.
- Fit a cake into a suet cage and hang it out of direct sun. Birds & Blooms and Grit both say to discard suet that smells rancid or shows mold, not to scrape it.
Mix-ins the sources name
Cornmeal, oats and flour as binders; sunflower, millet or cracked corn as seed; raisins or dried fruit; unsalted peanuts; and dried mealworms (Birds & Blooms, Audubon news, Georgia DNR, Cornell Lab). Choose unsalted nuts: Audubon (2011) and Birds & Blooms both specify them.
Which birds eat it
Woodpeckers, nuthatches, chickadees and titmice are the usual visitors (Birds & Blooms, Cornell Lab, Wild Birds Unlimited). See how to attract woodpeckers and best woodpecker feeders.
Where the sources disagree, and what we left out
Temperature limits. Audubon says its vegetarian cakes are for temperatures under 50°F; Audubon (2011) says fat can spoil quickly above about 50°F; Georgia DNR says suet melts and spoils quickly above 70°F; and Wild Birds Unlimited, which sells no-melt dough, says regular suet suits temperatures below 95°F and its dough withstands 130°F. The limits conflict, so we use the conservative one: treat 50°F as the cap for peanut butter and shortening cakes. Birds & Blooms includes a reader “no-melt” recipe that it says stays solid in warm weather, but it gives no temperature, so we cannot verify it.
Bacon drippings. Cornell Lab (2009) advises against them because of nitrosamines, while another source uses them. We omit them. Sugar, honey and bread appear in a few recipes with no clear guidance either way, so we leave them out of ours.
Soft peanut butter. Cornell Lab warns that oily or soft products can transfer oil to feathers and eggs during nesting, another reason to firm cakes up well and avoid feeding them in warm spring weather.
Limits and what the sources do not say
Several sources are old: Cornell Lab (2009), Audubon (2011 and 2016), Grit (2020). Only Birds & Blooms (December 2023), Audubon (modified October 2024) and Wild Birds Unlimited (a retailer, 2026) are recent, and we found no university-extension recipe. The sources do not give a tested shelf life at a given temperature, a safe microwave time, or a feeder-cleaning schedule. See how to clean a bird feeder for hygiene. We did not make or test any of these recipes, and we confirmed no Amazon product codes, so every link is a search link.
Questions about homemade suet
What is the easiest homemade suet recipe?
Birds & Blooms’ peanut butter and lard cake needs no rendering: equal parts melted lard and peanut butter stirred into oats, cornmeal, flour and birdseed, then chilled.
Can I make suet without lard?
Yes. Audubon’s vegetarian recipe uses shortening and nut butter. It is meant for cold weather, under 50°F.
Is homemade suet safe in summer?
Our sources advise against it. Audubon limits its recipe to temperatures under 50°F and Georgia DNR says suet melts and spoils quickly above 70°F.
How long can homemade suet stay out?
Sources give no tested number. Audubon (2011) suggests offering a day or two of suet at a time, and Grit advises a few days’ worth, in warm weather.
