Assembly Instructions

Making the Caramel Fudge
Achieving the ideal caramel fudge texture requires gentle, steady heat. Keep the mixture at a low simmer while stirring frequently. The caramel should thicken and darken slightly over 7 minutes. This step creates the signature fudgy consistency.
Adding White Chocolate
Incorporate finely chopped white chocolate into the hot caramel mixture. This creates a silky texture and adds subtle vanilla notes that enhance the caramel flavor. The residual heat melts the chocolate smoothly.
Working with Chocolate
Melt the coating chocolate slowly and gently. Use 30-second microwave intervals or a double boiler, stirring between each heating. The chocolate should be just melted when coating the cereal to maintain crispiness.
Creating Layers
Build the layers methodically for the best texture. Press the chocolate-coated cereal firmly into an even base. Pour warm caramel fudge over top and spread smoothly. Finish with the final chocolate coating, tapping gently to remove air bubbles.
Setting the Bars
Allow proper chilling time for clean cuts. Refrigerate for at least 2 hours, preferably overnight. Let bars stand briefly at room temperature before cutting. This prevents chocolate cracking.
Cutting and Serving
Use a heated knife blade for the cleanest cuts. Small squares work best given the rich flavor. Optional garnishes like drizzled chocolate add professional flair.

The combination of textures and flavors in these bars appeals to even those who typically avoid sweets. The contrast between smooth caramel, crisp cereal, and rich chocolate creates an addictive treat.

Serving Suggestions

These bars pair beautifully with coffee or tea. Fresh berries provide a lovely contrast when serving for dessert. They make an excellent addition to holiday cookie platters and complement cold milk perfectly.

Recipe Variations

Top with flaky sea salt for a modern twist. Substitute crushed pretzels for the cereal to create a sweet-salty combination. Add espresso powder to the caramel for coffee flavor. Crushed peppermint makes a festive holiday variation.

Frequently Asked Questions

→ Will dark chocolate work instead of milk chocolate here?
Definitely! You can use milk, dark, or even a mix of both. Dark chocolate brings a stronger cocoa taste and complements the sweetness of the caramel filling perfectly. If you're a dark chocolate lover, this is a great option.
→ Can I swap out the condensed milk in the recipe?
You can! Thick caramel sauce or dulce de leche are alternatives, but the consistency might differ slightly. Condensed milk gives the ideal creamy texture, so if you're substituting, you may need to adjust the cooking time to get it just right.
→ Are these a good treat to make ahead for parties?
Absolutely! These bars are even better when they’ve had time to set. Make them a couple of days prior and store them in the fridge in a sealed container. Slice them into squares right before you serve for the best results.
→ Why didn’t my caramel layer firm up properly?
It likely didn’t cook long enough. Simmering the caramel mixture for 5-7 minutes, until it's visibly thickened, is key. Mismeasured ingredients could also be the culprit, so be precise. Lastly, allow a minimum of two hours for the layers to fully chill, or leave it overnight for best results.
→ What can I use instead of Rice Krispies?
If you’re out of Rice Krispies, you can swap them for other cereals like puffed rice or crushed cornflakes. For a change in texture, you could try crushed graham crackers, biscuits, or pretzels - though these will make the base more crumbly instead of crispy.

Ingredients

→ Caramel Fudge Layer

01 60g butter, you can use salted or unsalted
02 100g light brown sugar
03 ½ a can (200g) of condensed milk
04 100g white chocolate, broken into smaller pieces
05 1½ tablespoons of honey or golden syrup

→ Chocolate Layers

06 75g of Rice Krispies cereal
07 650g of either milk or dark chocolate, split into portions

Instructions

Step 01

Grab an 8x8-inch (20x20cm) square baking tin and line it with parchment paper. Leave some extra paper hanging off the edges so it’s easy to take the bars out later.

Step 02

In a medium saucepan set over medium heat, toss in the condensed milk, butter, brown sugar, and golden syrup (or honey).

Step 03

Stir constantly until the mixture becomes smooth and the sugar dissolves completely. Let the mix simmer gently for 5 to 7 minutes while stirring occasionally, until it thickens into caramel fudge.

Step 04

Take the saucepan off the heat and stir in the white chocolate chunks right away. Keep mixing until the chocolate melts completely into the caramel. Let it cool down a bit as you move on to the chocolate layers.

Step 05

Melt all 650g of the milk or dark chocolate. Do this either by placing it in a heatproof bowl over simmering water (double boiler method) or heating it in the microwave in 30-second bursts, stirring in between, until smooth.

Step 06

Take half of the melted chocolate (about 325g) and stir it together with the Rice Krispies in another bowl until all the cereal is nicely coated.

Step 07

Spread the Rice Krispies-chocolate mix evenly into the lined baking tin to create a base. Use the back of a spoon to press it down firmly and make it uniform.

Step 08

Pour the fudge mixture over the chocolate-coated cereal base. Gently use a spatula to spread it evenly across the tin, getting it all the way into the corners.

Step 09

Pour the rest of the melted chocolate on top of the caramel layer. Spread it evenly using a spatula or tilt the tin to make sure it’s completely covered.

Step 10

Pop the tin into the fridge and let it chill for at least 2 hours, or until everything is set firmly.

Step 11

Take the set bars out of the fridge. Lift them out of the tin using the parchment paper and place them on a cutting board. Use a sharp knife to cut them into squares of whatever size you prefer.

Step 12

Serve the bars at room temperature for a softer bite, or keep them cold if you like them firmer. They go great with tea, coffee, or a glass of milk.

Notes

  1. You can use dark chocolate, milk chocolate, or mix the two to suit your taste.
  2. If you want an extra crunch, add an extra 25g of Rice Krispies to the base recipe.
  3. Store the bars in an airtight container in the fridge, and they’ll be good for up to a week.
  4. For clean slices, dip your knife in hot water and wipe it dry before cutting.
