3tablespoonsmilk (or your favorite non-dairy milk)
2tablespoonsvegetable oil
1teaspoonvanilla extract
2tablespoonschocolate hazelnut spread (such as Nutella)
a handfulchopped hazelnuts (for topping)
Instructions
In a microwave-safe mug, begin by adding the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, and salt. Use a fork or small whisk to mix these dry ingredients together thoroughly, breaking up any lumps.
Next, pour in the milk, vegetable oil, and vanilla extract. Stir the mixture gently until it forms a smooth batter, ensuring there are no clumps left.
Take the chocolate hazelnut spread and spoon it carefully into the center of the prepared batter. Do not mix it in; this step is crucial as it will create a gooey, molten center once cooked.
Place the mug in the microwave and cook on high for 40-60 seconds. Start checking the cake at the 40-second mark; it should rise nicely but still have a slight jiggle in the center, which indicates it will remain soft as it finishes cooking off the heat.
Once done, carefully remove the mug from the microwave (it will be hot, so use caution). Let the cake cool for about a minute to avoid burning your mouth.
Finally, sprinkle the warm mug cake with the chopped hazelnuts, adding a delightful crunch and flavor contrast to the rich chocolate.
Notes
Serve directly in the mug or on a plate. Drizzle extra chocolate hazelnut spread on top for an indulgent treat.
