Prepare Ingredients: Crush 4 Oreos into fine crumbs using a fork or place them in a ziplock bag and crush with a rolling pin.
Mix with Milk: In a microwave-safe mug (at least 10oz), add the crushed Oreos and pour in 4 tablespoons of whole milk. Mix until the Oreos form a thick paste-like consistency.
Incorporate Baking Powder: Add ⅓ teaspoon of baking powder to the mug and stir until well combined with the Oreo mixture.
Microwave: Microwave the mug cake on high power for 60-90 seconds. Start with 60 seconds and check the cake's doneness. It should be set but still slightly shiny on top. If needed, microwave for an additional 30 seconds until done.
Serve: Allow the mug cake to cool for about 1 minute before enjoying. Optionally, top it with whipped cream or additional crushed Oreos for added flavor and texture.
Enjoy: Savor the delightful warmth and chocolatey richness of your freshly made Oreo mug cake, right from the comfort of your mug.
