Ingredients for rice krispie squares recipe uk
Four crispy layers and melty marshmallow magicâjust seven ingredients for nostalgic perfection!
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal đȘ | 6 cups | Original or light variety preferred |
| Unsalted Butter đ§ | 1 cup | Cold, cubed for even melting |
| Mini Marshmallows đ„ | 6 cups | Extra large for extra gooeyness |
| Granulated Sugar đ | Âœ cup | For crispy edges and balance |
| Vanilla Extract đż | 1 tsp | Pure vanilla for authentic flavor |
| Salt đ§ | Âœ tsp | Kosher or sea salt preferred |
| Vegetable Oil đ« | 1 tbsp | For greasing the pan |
The butter makes or breaks these squares. Use unsalted so you control the saltinessâtrust me, it matters. Tesco or Sainsbury's have the best tubs for this, and always grab the full-fat version (the good stuff, not the pre-packaged spread). Mini marshmallows are a mustâthey melt faster and give that signature gooey texture. If you can only find regular marshmallows, chop them into quarters first. The cereal? Original Rice Krispies is the classic choice, but light works too if you prefer a slightly crispier texture.
No marshmallows? Substitute with fluffed rice cerealâitâs the secret weapon for that airy texture, though the filling wonât be as melty. Short on butter? Coconut oil works in a pinch, but it adds a subtle coconut flavor. The vanilla extract can be swapped for vanilla sugar (1 tsp) if youâre fresh out. For a fun twist, add a pinch of cinnamon to the cereal layerâkids love it! And if youâre making a big batch, double the sugar for extra crispy edges (just donât skip it entirelyâitâs what keeps those squares from turning gummy).
These squares stay fresh for 5 days in an airtight container, but honestly? Theyâre best eaten within 2 daysâthe marshmallow filling gets gummy over time. For parties, cut into smaller squares or trianglesâtheyâre always a hit! Store leftovers in the fridge, but bring them to room temperature before serving. Pro tip: Line your tray with parchment paper for easy slicing and no sticking. Freeze extras for up to 3 months if youâre really planning ahead.

Step-by-step instructions for buttery crispy Rice Krispie squares
Here's how to create those perfect golden layers with melty marshmallow goodnessâeasy, foolproof, and utterly delicious!
đł Step 1: Melt Butter and Sugar for the Base
Line an 8x8-inch baking dish with parchment paper, leaving an overhang for easy removal. In a large saucepan over medium heat, melt the 1 cup unsalted butter together with the 0.5 cup granulated sugar. I like to use a wooden spoon to stir constantlyâthis prevents burning and creates a smooth, golden mixture.
Watch closely as the butter melts completely and the sugar dissolves. You'll see tiny bubbles forming around the edgesâthat's your signal the mixture is ready. Remove from heat and stir in the 1 tsp vanilla extract and 0.5 tsp salt. This step is crucial for that perfect balance of sweetness and flavor in every bite.
đ„ Step 2: Cook the Marshmallow Mixture
Return the saucepan to low heat and add the 6 cups mini marshmallows. Stir gently but constantly with a wooden spoonâthis prevents the marshmallows from sticking to the bottom. You'll see them begin to melt and the mixture will become thick and glossy.
Here's the thingâdon't rush this step. The marshmallows need time to fully melt and create that signature gooey texture. When the mixture is completely smooth and looks like thick caramel, remove it from heat immediately. This usually takes about 3-4 minutes of gentle stirring.
đšâđł Step 3: Grease the Pan and Assemble Layers
Quickly brush the prepared baking dish with the 1 tbsp vegetable oil using a paper towelâthis prevents sticking. Pour half of the melted marshmallow mixture into the bottom of the dish and spread it evenly with a spatula. Then sprinkle 3 cups of the rice krispies cereal over the top, pressing down gently but evenly.
Here's where it gets funârepeat the process with the remaining marshmallow mixture and the final 3 cups of rice krispies cereal. Press down firmly but don't compact too tightlyâyou want those crispy layers to hold their shape but still be light. The secret to perfect squares is even distributionâno clumps or bare spots!
â° Step 4: Press and Chill for Perfect Texture
Using a second spatula, press down firmly on the top layer to create an even surface. I like to use the back of a spoon to smooth out any ridges. Let the squares cool in the pan for 10 minutesâthis helps them set slightly before cutting.
Transfer the baking dish to the refrigerator and chill for at least 2 hours, or until completely firm. This chilling time is non-negotiableâit allows the layers to set properly and prevents the squares from being too soft or crumbly. The longer they chill, the better they'll hold their shape when you cut them.
đȘ Step 5: Cut and Enjoy Your Crispy Treats
Once fully chilled, lift the squares out of the pan using the parchment overhang. Using a sharp knife, cut into 16 equal squares (about 2-inch squares each). For clean cuts, dip the knife in hot water between each cut and wipe dryâthis prevents the cereal from sticking.
Serve immediately for warm, gooey squares, or store in an airtight container at room temperature for up to 5 days. These squares are perfect for snacking, school lunches, or as a sweet treat with your afternoon tea. The contrast of crispy cereal and melty marshmallow in every bite is pure magic!
Pro Tips For Making Rice Krispie Squares Recipe Uk
- Melt Butter Slowly: Use low heat for the butter-sugar mixâboiling it turns the marshmallows rubbery. I learned this the hard way after making a batch that tasted like chewy regret.
- Toast Cereal First: Spread uncooked Rice Krispies on a baking tray and toast in the oven at 160°C (320°F) for 5 minutes before mixing. It adds a nutty depth and prevents soggy squares.
- Add Vanilla Late: Stir in the vanilla extract after removing the pan from heatâit burns easily and ruins the delicate marshmallow flavour. I used to add it too soon and ended up with a bitter aftertaste.
- Press Firmly: Use a greased 20x20cm (8x8-inch) tin and pack the mixture down with a spatula. The first batch I made was too loose, and the squares fell apart when cuttingânow I press until itâs almost resistant.
Essential equipment for this dish
Essential Baking Dish
An 8x8-inch baking dish is your best friend for this recipeâI swear by Tefal Ceramic or Wilton Heavy Gauge Aluminum for even heat distribution. Avoid non-stick pans with low sidesâthey wonât hold the layers properly.
If youâre short on space, a 9x9-inch dish works too, just increase chilling time by 30 minutes. đ§âđł
Mixing Tools
Use a large saucepan with sloped sides (like Le Creuset) for melting butter and marshmallowsâitâs easier to stir and prevents spills. A wooden spoon is non-negotiable; metal spoons can scratch your pan or burn the mixture.
For pressing layers, grab a 9-inch cake pan or round spatulaâthey help create that perfect even surface.
Cutting Equipment
A sharp chefâs knife (like WĂŒsthof) is key for clean cuts, but hereâs the trick: dip it in hot water between each slice to prevent sticking. For extra precision, use a wire cooling rack to hold the squares while cuttingâit keeps them stable.
If youâre making a big batch, a pizza cutter works too, but expect slightly thicker slices.
Measuring Essentials
Invest in a stainless steel measuring cup set (I love OXO Good Grips) for accurate butter and sugar measurementsâpacked butter can vary wildly! A gram scale takes the guesswork out of marshmallows (aim for 150g per cup).
For the cereal, a large scoop or funnel speeds up layeringâno more spills or uneven distribution. đ
Optional Pro Tools
For melty perfection, a thermometer (like Thermoworks Thermapen) helps track the marshmallow mixtureâit should reach 110°C (230°F). A parchment paper roll saves time when lining your pan, and kitchen twine makes gift-wrapping these squares effortless.
If youâre ambitious, a stand mixer with a paddle attachment can handle the marshmallow melting for youâjust set it to low speed to avoid splatter.

Frequently asked questions
Can I use regular marshmallows instead of mini marshmallows?
Yes, but you'll need to chop them into quarters first! Regular marshmallows melt slower and won't create that signature gooey texture. For best results, use extra large mini marshmallowsâthey melt faster and give that perfect marshmallow filling. If you're in a pinch, fluffed rice cereal works as a substitute, though the texture will be slightly different.
Why are my Rice Krispie squares too soft or crumbly? This usually happens from improper chilling time or overmixing.
Can I make these squares without butter?
You can substitute butter with coconut oil for a dairy-free version, though it will add a subtle coconut flavor. For a neutral taste, use vegetable shortening instead. Just remember that butter gives these squares their signature richness and crispy texture, so the result won't be exactly the sameâbut it'll still be delicious!
How do I store these squares for maximum freshness?
Store them in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for up to 3 monthsâjust wrap each square individually in cling film before freezing. When ready to eat, let them come to room temperature for 10-15 minutes before serving. The marshmallow filling stays best when kept cool, so avoid leaving them out in warm conditions.
Whatâs the best way to cut clean squares every time?
Use a sharp knife and dip it in hot water between each cut to prevent sticking. Wipe it dry before cutting again. For extra precision, chill the squares for 30 extra minutes before cuttingâthey'll hold their shape better. If you're making a big batch, a pizza cutter works well too, though you'll get slightly thicker slices.
