20 Peanut Butter Desserts Our Community Can’t Stop Making

Peanut butter has a way of turning any dessert from good to completely addictive. That salty-sweet richness, the way it clings to the roof of your mouth, the depth it brings to chocolate, caramel, and even fruit — there's a reason it sits at the centre of so many home baking traditions across Australia and beyond. As autumn settles in and the evenings cool down, the urge to bake something warm and deeply satisfying hits harder than ever. These are the twenty peanut butter desserts our community has been baking on repeat, the ones that get photographed, shared, and requested again before the last crumb disappears.

What you'll find here isn't a random collection. Every recipe below has been tested, loved, and passed around by real home cooks who care about flavour and texture in equal measure. Some are quick enough for a weeknight craving. Others deserve a weekend afternoon and a kitchen covered in flour. Whether you work with smooth, crunchy, or a natural variety with nothing but peanuts and salt, there's something here that will earn a permanent spot in your rotation. Time to pull that jar out of the pantry.

Classic peanut butter cookies

Three ingredients — peanut butter, sugar, and one egg — produce a cookie with a crackled top and a chewy centre that tastes far more complex than the recipe suggests. The trick is using a full-fat peanut butter with a good roast flavour, not the low-sugar varieties that tend to bake dry. Press a crosshatch pattern with a fork, bake at 180°C for 10–12 minutes, and pull them when they still look slightly underdone. They firm up as they cool, leaving you with a texture somewhere between shortbread and fudge.

Peanut butter brownies

A dark chocolate brownie batter swirled with ribbons of melted peanut butter creates a contrast that keeps you reaching for another square. The key is dropping spoonfuls of warmed peanut butter onto the surface and dragging a skewer through in figure-eight motions — not mixing it in, just marbling. The brownie stays dense and fudgy while the peanut butter streaks add pockets of salt and roast.

No-bake peanut butter cheesecake

A biscuit base made from crushed digestives and melted butter, topped with a filling of cream cheese, peanut butter, icing sugar, and whipped cream. It sets in the fridge overnight and slices cleanly the next day. Community members swear by adding a thin layer of melted dark chocolate between the base and the filling — it acts as a moisture barrier and brings a bitter edge that balances the richness.

Peanut butter banana ice cream

Frozen banana chunks blitzed in a food processor with two tablespoons of peanut butter until smooth and creamy. No dairy, no added sugar, and a texture that genuinely resembles soft-serve. A pinch of flaky salt on top transforms it. Some community bakers fold through roughly chopped dark chocolate at the end for a chunky finish.

Chocolate peanut butter tart

A press-in cocoa shortcrust filled with a ganache made from dark chocolate, cream, and a generous measure of smooth peanut butter. The filling is poured warm and left to set at room temperature for a glossy, truffle-like finish. Serve thin slices — this is extraordinarily rich. A scattering of roasted peanuts on top provides crunch and visual contrast.

Peanut butter blondies

Where brownies lean on cocoa, blondies lean on brown sugar and butter, and adding peanut butter to that base creates something caramelly and dense with a toasted flavour that fills the kitchen. Fold white chocolate chips through the batter for pockets of sweetness. Underbake by two minutes for a centre that stays soft for days.

Peanut butter stuffed dates

Medjool dates, split and pitted, filled with a teaspoon of crunchy peanut butter and finished with a drizzle of melted dark chocolate and flaky sea salt. Five minutes of work, no oven required. These have become the community's go-to when someone needs a dessert for a gathering but has no time to bake. The natural caramel sweetness of the date against the salt and fat of the peanut butter is a combination that works on every level.

Peanut butter mousse

Whipped cream folded into a base of peanut butter, icing sugar, and softened cream cheese. Spooned into glasses and chilled for an hour, it firms into a mousse with a texture like aerated peanut butter fudge. A crumble of crushed peanut brittle on top gives each spoonful a snap. Light enough to follow a heavy meal, flavourful enough to stand as the main event.

Peanut butter and jam thumbprint cookies

A peanut butter shortbread dough, rolled into balls, pressed with a thumb, and filled with strawberry or raspberry jam before baking. The jam caramelises slightly at the edges during baking, concentrating its flavour. The result is a cookie that tastes like the sandwich you grew up eating, reimagined as something you'd serve on a platter with coffee.

Peanut butter fudge

Condensed milk, peanut butter, butter, and a splash of vanilla, heated together and poured into a lined tin. It sets in the fridge within a few hours into a smooth, sliceable fudge with a melt-in-the-mouth quality. The margin for error is small — overheating causes graininess — so keep the heat low and stir constantly. Cut into small squares; this is intensely sweet and a little goes a long way.

Peanut butter granola bars

Oats, peanut butter, honey, and a handful of dark chocolate chips pressed into a tin and chilled. No baking, no fuss, ready in under an hour. These hold together better than most homemade bars thanks to the binding power of the peanut butter. Community members add desiccated coconut, chia seeds, or dried cranberries depending on what's in the pantry. They keep well in the fridge for up to a week, wrapped individually.

Peanut butter swirl banana bread

A standard banana bread batter — overripe bananas, brown sugar, butter, flour, eggs — with dollops of peanut butter swirled through before baking. The peanut butter creates veins of flavour throughout the loaf that stay slightly gooey even after baking. Use bananas that are genuinely black-spotted and fragrant for the deepest flavour. Bake in a 165°C oven for 55–65 minutes, testing with a skewer.

Peanut butter cup truffles

A chilled mixture of peanut butter, icing sugar, and crushed biscuit crumbs, rolled into balls and dipped in tempered dark chocolate. The inside stays soft and sandy while the shell gives a clean snap. Let them set on baking paper in the fridge. These disappear within hours at any gathering — make a double batch as a rule.

Peanut butter pancakes

A tablespoon of peanut butter whisked into your standard pancake batter changes the texture entirely — denser, richer, with a nutty aroma that rises from the pan. Top with sliced banana, a drizzle of honey, and a scattering of crushed roasted peanuts. These work just as well as a dessert course as they do for a weekend breakfast, particularly when served with a scoop of vanilla ice cream on the side.

Peanut butter mug cake

Two minutes in the microwave produces a single-serve cake with a molten peanut butter centre. The batter — peanut butter, self-raising flour, milk, sugar, and an egg — comes together in the mug itself. The edges set while the middle stays almost sauce-like. It's not elegant, but at ten o'clock on a Tuesday night when the craving strikes, nothing else competes.

Peanut butter pavlova

A classic Australian pavlova shell — crisp outside, marshmallow within — topped with a cream filling rippled through with smooth peanut butter and finished with shards of peanut brittle and a dark chocolate drizzle. This combination sounds unlikely, but the community response has been overwhelmingly enthusiastic. The airy meringue offsets the heaviness of the peanut butter cream, and the brittle provides a textural crunch that a traditional pav often lacks.

Peanut butter rice crispy treats

Melted butter, marshmallows, and a generous scoop of peanut butter stirred through puffed rice cereal and pressed into a tin. They set within thirty minutes at room temperature. The peanut butter version has a chewier, more cohesive texture than the original and a toasted depth that plain marshmallow can't achieve. Cut into thick bars and drizzle with milk chocolate for something truly indulgent.

Peanut butter and chocolate layer cake

A two-layer chocolate sponge filled and covered with peanut butter buttercream — the kind of cake that draws people across the room. The buttercream is simply butter, icing sugar, peanut butter, and a splash of cream, beaten until pale and fluffy. The salt in the peanut butter tempers the sweetness of the icing, making it possible to eat a generous slice without feeling overwhelmed. Decorate with chopped peanuts and chocolate shavings for a finish that looks as striking as it tastes.

Peanut butter energy balls

Rolled oats, peanut butter, honey, flaxseed, and dark chocolate chips mixed and rolled into bite-sized balls. No baking. They firm up in the fridge within an hour and keep well for five to seven days. People use these as afternoon pick-me-ups, lunchbox additions, and pre-workout fuel. The ratio that works best: equal parts oats and peanut butter by volume, with half that amount of honey to bind.

Peanut butter semifreddo

A frozen Italian dessert made by folding whipped cream and a peanut butter caramel through a zabaglione base, then freezing in a loaf tin lined with cling film. Sliced straight from the freezer, it has the texture of frozen mousse — creamy, never icy — with ribbons of salted caramel and peanut running through each piece. This is the recipe people describe as their "secret weapon" for dinner parties. It's made entirely in advance, requires no ice cream machine, and looks spectacular on the plate with a scattering of chopped roasted peanuts and a drizzle of warm chocolate sauce.

Choosing the right peanut butter for baking

Not all peanut butters perform the same way in desserts. Commercial smooth varieties with added oil and sugar — the kind that don't separate in the jar — give the most consistent results in cookies, brownies, and fudge. They cream well with butter and sugar and produce a predictable texture. Natural peanut butters, made from ground peanuts alone, have a more intense roast flavour but can make baked goods drier or denser. If you prefer natural, stir the jar thoroughly before measuring and consider adding an extra tablespoon of butter or oil to the recipe to compensate for the lower fat content. Crunchy peanut butter works anywhere you want texture — blondies, granola bars, stuffed dates — but switch to smooth for anything that needs to be silky, like mousse, cheesecake filling, or buttercream.

Storage and make-ahead tips

Most peanut butter desserts store better than their non-peanut butter counterparts. The fat in the peanut butter acts as a natural preservative and keeps baked goods moist for longer. Cookies stay chewy in an airtight container at room temperature for up to five days. Brownies and blondies can be wrapped tightly and frozen for up to three months — thaw at room temperature for an hour before serving. No-bake desserts like cheesecake, fudge, and energy balls hold well in the fridge for a week. The semifreddo can be frozen for up to two weeks without any loss in texture, making it a genuine make-ahead showstopper.
