This Peanut Butter Rice Bubble Slice is going to become your new favourite. I love Keke Puarere (rice bubble slice), but a lot of versions I’ve tried are way too sweet and that “sticks to your teeth” kind of situation. So I created a salty-sweet peanut butter rice bubble slice made without refined sugar. It’s naturally sweetened, packed with crunch from seeded peanut butter, and has that perfect balance of chewy and crisp.

Get ready for a party in your mouth e te whānau (family)! 🎉

Three pieces of Peanut Butter Rice Bubble Slice are stacked on top of each other in a close shot showing texture and a chocolate topping with freeze-dried strawberries.

Why you will love this Peanut Butter Rice Bubble Slice:

This amazing no-bake slice is everything I love in a simple snack or lunchbox filler. It’s quick to make, naturally sweet, and packed with crunchy, nutty goodness. I’ve used Pic’s Seed and Nut Mix in this recipe, but you can easily swap it for your favourite nut or seed butter.

I can’t wait for you to try it—e te whānau (family), it really is so good 😊

MORE PEANUT BUTTER GOODNESS:

If you love peanut butter recipes, you’ll want to try a few more of my favourites.

Is Witipiki (Weetbix) are more your vibe? Then my Peanut Butter Weetbix Slice is a perfect easy snack or lunchbox treat. If you’re craving a purini (dessert), take a look at my No-Bake Peanut Butter Pie or my Peanut Butter Jelly Cheesecake for something extra indulgent.

INGREDIENTS:

A wooden board sits on a cream cloth on a wooden table. On the board is a blue plate with ingredients on it in vintage bowls and jars. There is seeded peanut butter, rice syrup, keto muesli, butter and Rice Bubbles in view with flowers in the background. A ceramic spoon sits at the from of the planet with cinnamon in it.
  • Cereal: Use pū kākano keto (keto muesli) or any granola or muesli.
  • Butter: Use salted or unsalted pata (butter).
  • Brown Rice Malt Syrup: I highly recommend this product because it is an unrefined sugar but is cheaper than maple syrup. It adds a soft sweetness to the slice but can be swapped for the same amount of date syrup or maple syrup.
  • Peanut Butter: I use Pic's pata kākano me te nati (seed and nut mix butter) for the ultimate texture but feel free to swap it for smooth or crunchy.
  • Mixed Spice: The raukikini whakauruuru (mixed spice) gives a subtle hum of flavour in the background but can be removed or swapped for another spice.

HOW TO MAKE THIS CRUNCHY SLICE:

Note: The full recipe card with the full list of ingredients, instructions and step by step video are found at the bottom of this page.

A black cast iron pan sits on a black stove top. In it is a simple caramel bubbling. Eggs in a wire basket are in the background.

1. Prepare the Slice Tin:

Line a 20 cm slice tin with baking paper.

2. Boil the Simple Caramel:

Set a frying pan or large pot over medium heat.

Add the pata (butter) and mīere raihi parauri (brown rice malt syrup) in to the pan or pot. Bring the simple karamea (caramel) to a simmer, stirring occasionally for a couple of minutes.

Once it is bubbling and starts to thicken, reduce the heat to low. Then add the pata kākano me te nati (seed and nut mix butter), raukikini whakauruuru (mixed spice), wanira (vanilla) and (tote). Stir for another minute and remove from the heat.

A vintage bowl sits on a blue plate with natural fabric under it. In the bowl is a Rice Bubble mixture that is being stirred with a wooden spoon. A orange candle is burning in the background with purple flowers.

3. Combine the Rice Bubbles and Peanut Butter Caramel:

Add the puarere (rice bubbles) and pū kākano (muesli) in to a large bowl.

Pour the warm peanut butter caramel in to the puarere (rice bubbles) and pū kākano (muesli).

Whakaranuhia te katoa (combine everything together).

A black tin lined with brown baking paper sits on natural fabric. In the tin is Peanut Butter Rice Bubble Slice that is being pressed down firmly with a large vintage spoon.

4. Press the Mixture in to the Tin:

Add the mixture in to the prepared slice tin and press it down firmly with the back of a spoon.

Take the time to do this so the slices stays together when it is set.

Refrigerate for 20 minutes and it is ready to be eaten like this or add the chocolate topping like I did.

A black tin lined with brown baking paper sits on natural fabric. In the tin is Peanut Butter Rice Bubble Slice that has been decorated with chocolate, keto muesli and freeze-dried strawberries.

5. Add the Chocolate Topping (Optional). 

Chop the tiakarete (chocolate) in to small pieces and then add it, along with the noni (oil) in to a small pot. 

Gently melt it over a low heat and then pour it directly over the keke papatahi puarere (rice bubble slice). Spread it out. 

If you want to, decorate with pū kākano anō (extra muesli) and rōpere tauraki-tio (freeze dried strawberries.
