Instructions
Peanut Butter Cake:
- Preheat oven to 180°C (350°F) or 160°C (320°F) for fan-forced. Grease and line a quarter sheet pan with parchment paper.
- In a large bowl, cream butter, brown sugar, and caster sugar until pale and fluffy. Add peanut butter and vanilla extract; mix until smooth.
- Add eggs, one at a time, mixing on low speed.
- Sift in baking powder, salt, and half the flour. Pour in all the milk and mix on low speed. Add remaining flour and mix until smooth.
- Pour batter into the prepared pan and bake for 35-40 minutes or until golden and a toothpick inserted in the center comes out clean. Cool completely.
Chocolate Frosting:
- In a bowl, beat butter on medium speed until pale and creamy (2-3 minutes).
- Melt chocolate in the microwave in 20-second intervals, stirring in between. Let cool slightly.
- Add half the icing sugar and 1 tbsp of milk to the butter. Beat on low until combined. Add remaining sugar and milk, and beat again.
- Stir in melted chocolate and peanut butter. Beat until smooth. Add more milk if needed to adjust consistency.
- Spread frosting over the cooled cake and top with mini M&M’s.
Notes
- Use processed peanut butter for best results.
- Allow the cake to cool completely before frosting.
