One Bowl Peanut Butter Dog Biscuits That Last Two Weeks

One bowl peanut butter dog biscuits are what I make when I want something simple that does not involve weighing ingredients, setting timers for multiple stages, or ending up with flour on every surface in the kitchen. You mix everything in a single bowl, roll it out, cut shapes and your dogs will eat them without hesitation (bonus they keep well enough to justify making a batch).

I have tried plenty of dog biscuit recipes over the years. Some involved oat flour and banana and came out too soft. Others needed three bowls and still tasted like cardboard. The ones that worked were always the simplest ones, and this is about as simple as it gets without just handing the dog a carrot.

What You Need

This is not a long shopping list. Most of what goes into these biscuits is already in the cupboard if you bake occasionally or keep peanut butter around.

Peanut butter: Smooth works better than crunchy for mixing, and it needs to be the plain kind with no xylitol, no added sugar, and ideally just peanuts and maybe a bit of salt. Check the label every time because brands change their recipes without warning.
Whole wheat flour: Plain flour works too, but whole wheat gives the biscuits a bit more texture and holds together well without being heavy. You need about two cups, give or take.
Egg: One large egg binds everything together. If the dough feels too dry after mixing, you can add a tiny splash of water, but the egg usually does the job on its own.
Water: Just a few tablespoons to bring the dough together. Start with two and add more if needed. The dough should be firm enough to roll but not crumbly.

That is the entire ingredient list. No baking powder, no flavourings, no optional add-ins that make the recipe longer than it needs to be. If you want to add something extra like a handful of oats or a bit of grated carrot, go ahead, but it works without any of that.

How to Make Them

Preheat the oven to around 180°C. Line a baking tray with greaseproof paper or just use a tray that does not stick too badly. I have done both and it makes no real difference to how the biscuits turn out.
Put the peanut butter in a bowl. Add the egg and mix it until it is smooth enough that you cannot see streaks of egg white. Then add the flour in two or three goes, mixing as you go. It will start to clump together fairly quickly. Add water a tablespoon at a time until the dough holds together when you press it. You are aiming for something that feels like pastry dough, firm but not dry.
Turn the dough out onto a clean surface. If it is sticky, dust the surface with a bit more flour. Roll it out to about half a centimetre thick. Thicker and the biscuits take longer to bake and stay softer in the middle, which some dogs prefer but which does not keep as well. Thinner and they go too hard and can chip a tooth if your dog is enthusiastic.
Cut shapes if you have cutters. I usually just slice the dough into squares with a knife because it is faster and wastes less dough. Put the shapes on the baking tray with a bit of space between them. They do not spread much, but they do puff up slightly.
Bake for about twenty to twenty-five minutes, depending on thickness. They should be firm to the touch and just starting to brown at the edges. Let them cool completely on a wire rack before you give one to the dog. They harden as they cool, and a warm biscuit will crumble.

What Dogs Actually Think of Them

Most dogs will eat these without hesitation. Peanut butter is one of those flavours that seems to register immediately, and the texture is firm enough that it takes a bit of chewing, which most dogs seem to enjoy. I have yet to meet a dog that turned one down, though I am sure there are exceptions somewhere.

If your dog is not interested, check the peanut butter you used. Some brands have very little actual peanut flavour and more oil or filler. The stronger the peanut taste, the more likely the dog will want it. You can also try rolling the dough slightly thinner and baking it a bit longer so the biscuits are crunchier, which some dogs prefer.

How Long They Keep

Stored in an airtight container or a sealed bag, these biscuits last about two weeks at room temperature. Longer than that and they start to lose flavour, though they do not go off in any obvious way. If you want to keep them longer, freeze them in a freezer bag and take out a few at a time as needed. They defrost in about ten minutes on the counter.

I usually make a batch, keep some out for the week, and freeze the rest. It means I am not baking every few days, and the dog does not notice any difference between fresh and defrosted.

Common Problems and How to Fix Them

Occasionally something goes wrong. The dough might be too dry, the biscuits might spread too much, or they come out softer than expected. Here is what usually causes it and how to adjust.

Dough too dry and crumbly: Add water a teaspoon at a time and knead it in until the dough holds together. If you have already added quite a bit of water and it is still dry, the flour might be absorbing more than usual. A tiny bit more peanut butter can help.
Dough too sticky: Dust your hands and the surface with more flour. If it is very sticky, you may have added too much water or used a particularly oily peanut butter. Add flour a tablespoon at a time until it is workable.
Biscuits spread or puff up too much: The dough was probably too wet or too warm when it went in the oven. Chill the dough in the fridge for fifteen minutes before rolling it out next time, and make sure you are not adding more water than needed.
Biscuits too soft after baking: Either they were rolled too thick or did not bake long enough. Put them back in the oven for another five to ten minutes and let them cool completely. They should firm up as they cool.

Adjustments for Older Dogs

If your dog is getting older, you might need to adjust the texture. Hard biscuits can be difficult for dogs with dental issues or weakened jaw strength. Roll the dough slightly thicker and bake for a shorter time so the biscuits stay a bit softer in the centre. They will not keep quite as long, but they are easier to chew.

You can also break the biscuits into smaller pieces before giving them. Older dogs sometimes struggle with larger treats, and a smaller piece is easier to manage without making them work too hard for it. If you are unsure where your dog sits in terms of age and what that means for their needs, the Do g Years to Human Years Calculator gives you a more accurate picture than the old seven-to-one rule.

Why This Recipe Works

The reason this works is that it doesn’t rely on precise measurements or techniques that only make sense if you bake regularly, and it also produces a biscuit that actually tastes like something. A lot of homemade dog treats come out bland or smell faintly of nothing, and dogs lose interest quickly. Peanut butter has enough flavour to dominate the biscuit, and the texture is satisfying enough that most dogs will chew it rather than just swallow it whole.

What Not to Add

There are plenty of recipes that suggest adding honey, cinnamon, or other flavourings. I would leave them out. Honey adds sugar that dogs do not need, and cinnamon can be an irritant in larger amounts. The biscuits work fine without any of it, and simpler is usually better when it comes to what dogs eat.

Do not add chocolate, raisins, grapes, onion, garlic, or anything with xylitol. Those are all toxic to dogs in varying degrees, and there is no safe amount. If you are adding anything beyond the basic recipe, check it first.

When to Use Them

These work well as training treats if you break them into small pieces. They are also fine as an occasional snack or something to occupy the dog for a few minutes. I do not use them as a meal replacement or a daily staple, just as something extra that the dog enjoys and that I know exactly what went into.

If your dog has allergies, a sensitive stomach, or any kind of dietary restriction, check with your vet before introducing anything new. Peanut butter and wheat are generally well tolerated, but every dog is different.
