Peanut Butter Chocolate Cupcakes

1: Preheat the oven to 180°C or 350°F, then line a 12 hole muffin tray with cupcake cases.

2: Melt the margarine in a saucepan on a low heat, then add to a mixing bowl with the remaining cake ingredients.

3: Gently mix the cupcake ingredients until fully combined.

4: Spoon 2 tbsp of mixture into each cupcake case or fill until each case is roughly 3/4 full.

5: Bake in the preheated oven for 22-24 minutes or until a skewer comes out clean.

6: Remove the muffin tray from the oven and transfer the cupcakes to a cooling rack. Leave the cakes to cool completely.

7: Meanwhile, prepare the frosting by transferring the frosting ingredients to a mixing bowl and combining until smooth. If too thick, add more milk a small amount at a time.

8: Transfer the frosting to a piping bag.

9: Pipe a generous amount of frosting onto the cupcakes and top with crushed peanuts and pretzels.

10: Finish with a single pretzel on top of each cupcake.
