These bars are indulgent, gooey and fudgy with a sweet white chocolate finish — a perfect homemade gift or celebration dessert. They’re easier to make than they look; the most time-consuming part is waiting for each layer to cool and set.

Ingredients

Use good quality ingredients where you can — they make a noticeable difference in flavour and texture.

Red velvet brownie

  • Butter: Unsalted is best so you control the salt.
  • Sugar: Golden caster or superfine sugar works well.
  • Cocoa powder: Use pure cocoa powder, not drinking chocolate.
  • Eggs: Large eggs (plus one yolk) for structure and richness.
  • Vanilla: A good-quality extract improves flavour.
  • Red food colouring: Gel colouring gives a vivid red without thinning the batter.
  • Flour: Plain/all-purpose flour — not self-raising.
  • Salt: Table salt dissolves easily in the batter.
  • Vinegar: White wine vinegar adds a subtle tang; white distilled or cider vinegar can be used instead.

Caramel

  • Sweetened condensed milk: The base of the caramel.
  • Butter: Unsalted gives control over saltiness.
  • Sugar: Golden caster adds a light caramel flavour.
  • Golden syrup: Adds texture and depth; corn syrup is a US alternative.
  • Vanilla and salt: Finish the caramel and balance sweetness.

Chocolate topping

  • White chocolate: Use a decent quality white chocolate for the best flavour.

Recipe summary

Red velvet brownie

  1. Melt butter, beat in sugar and cocoa powder, then add egg, yolk, vanilla and red gel, mixing well.
  2. Fold in flour and salt, stir in vinegar, then bake in a lined square tin for 18–20 minutes.

Caramel

  1. Combine condensed milk, butter, sugar, golden syrup, vanilla and salt in a saucepan and stir constantly.
  2. Boil and simmer, stirring until it reaches about 107°C/225°F and turns golden.
  3. Remove from heat, stir a few minutes, then pour over the cooled brownie layer.

Chocolate topping

  1. Melt white chocolate gently in 10-second bursts in the microwave, stirring between intervals.
  2. When mostly melted, remove from heat and stir until smooth.
  3. Pour over the caramel, allow to set, then slice into bars.

Recipe tips

These tips will help you get clean layers and great texture:

  1. Read the entire recipe before you start so you’re prepared for each stage.
  2. Weigh and prep ingredients for each section ahead of time.
  3. Allow each layer to cool completely before adding the next to keep layers neat.
  4. Stir the caramel constantly and scrape the edges to prevent burning.
  5. Use a sugar thermometer to check the caramel temperature for consistent results.
  6. If the caramel picks up burnt bits, sieve it while still hot to remove them.
  7. Heat chocolate gently and stop microwaving when it’s two-thirds melted — stirring will finish it.

Storage

Store the bars in a metal tin at room temperature and eat within seven days. Avoid refrigerating, which can dry them out — you want these to stay gooey and fudgy.
