Chocolate Peanut Butter Slice

CC · April 10, 2021 ·

Peanuts and chocolate are a dependable combination and this chocolate peanut butter slice is a vegan variation on a familiar theme, this time with a crunchy cocoa-rich biscuit base which makes it extra chocolatey.

As you might expect, it’s a really easy recipe, and you can use your preferred peanut butter: crunchy is good for texture, obviously, but smooth is easier to spread over the base!

The base is the only part that requires any baking. It’s a rich shortcake with a high ratio of cocoa and cornflour to flour which makes it extra crisp. Despite its crispness, it cuts cleanly with a sharp knife and doesn’t break away from the top layers.

Use a chocolate you like for the topping – I find the very dark 70%+ varieties can overwhelm the other flavours in a traybake.

The quantities here will make 16 thin slices (as pictured) in an 8″ square tin.

Chocolate Peanut Butter Slice…

Ingredients

  • 45 g soft vegan margarine
  • 25 g coconut oil
  • 50 g brown sugar
  • 20 g cocoa powder
  • 20 g cornflour
  • 60 g plain white/unbleached flour
  • 160 g peanut butter (smooth or crunchy)
  • 60 g icing (confectioner’s) sugar
  • 150 g dark chocolate

Method

  1. Set the oven to 180°C/360°F and lightly oil/line the base of an 8″ tin (or a smaller tin for a thicker slice). It’s not strictly essential to line the tin, but it ensures the base will come out in one piece.
  2. Soften the coconut oil a little in the microwave if it’s not already of a similar consistency to the margarine.
  3. Beat the coconut oil, margarine and brown sugar in a large bowl until light and fluffy.
  4. Sift in the cocoa, cornflour and flour and work together with a fork until it forms a biscuit dough.
  5. Roll the dough to roughly the right size on a lightly floured board, then transfer to the tin and press it into the corners. It won’t matter if it breaks up – just press it back together in the tin.
  6. Bake the base for around 10 minutes, until it’s just about starting to darken at the edges, then remove and set aside to cool.
  7. Soften the peanut butter on a low heat in the microwave to make it easy to spread. Add the icing sugar and mix well with fork before transferring to the biscuit base. Spread with a knife to create a fairly smooth surface. Allow it to cool before adding the chocolate.
  8. Melt the chocolate gently in the microwave (or in a double boiler) and drizzle it over the peanut butter layer, then spread gently with a knife to ensure it reaches the edges.
  9. Wait until the chocolate has set completely before cutting squares carefully using a sharp knife.
