It does not get any easier than this! And I was surprised at how lovely this cake really is. I tested quite a few versions – not complaining about that – and the cake really is light and fluffy. The egg yolk keeps it from getting too dry and the peanut butter adds delicious flavour.
A few drizzles of jam for sweetness and its the perfect way to satisfy your peanut butter and jelly cravings. It’s also great if you have a few guests over – people will love making their own mug cakes! I’ve also got recipes for a Nutella Chocolate Mug Cake and a Vanilla Chocolate Chip Mug Cake if you want to try.
Whatever the flavour, I am completely sold on mug cakes. They are the best! So quick and easy. My only advice would be to use a kitchen scale if you can. Because there’s such a small amount of batter, you really want to get all those ratios just right.
So why not make yourself a treat tonight? I bet you have ALL the ingredients for this beauty sitting in your pantry right now. Gosh, I think I might need to go make another one. Happy baking!
Let’s Bake
Peanut Butter and Jelly Mug Cake
An easy Peanut Butter and Jelly Mug Cake made in the microwave.
Ingredients
- 45 grams (1/4 cup + 2 tablespoons plain flour)
- 3 tablespoons brown sugar
- 1/4 teaspoon baking powder
- 30 grams (2 tablespoons) unsalted butter
- 3 tablespoons milk
- 1/2 teaspoon vanilla extract
- 1 egg yolk
- 1 tablespoon smooth peanut butter
- 1 tablespoon strawberry jam
Instructions
In a small bowl, sift the plain flour, then add the sugar and baking powder. Give it a stir. In a separate bowl, add the butter and microwave until just melted. Add the milk, vanilla and egg yolk to the melted butter and whisk gently. Add the peanut butter and stir – it’s ok if it’s a little lumpy.
Then add the wet ingredients to the dry ingredients and stir until combined. Pour cake batter in a mug, then microwave your cake for approximately 1 minute and 40 seconds* (900W microwave). Leave to cool for a minute or two, then add a tablespoon of strawberry jam on top.
Notes
Adjust the time accordingly if your microwave is more/less powerful. The cake should be slightly firm on top and spring back when lightly touched.
