Yes, you can definitely bake a chocolate peanut butter mug cake in the oven instead of the microwave. The process will be slightly different, but it can be done. Here's a general outline of how you can adapt a mug cake recipe for baking in the oven: Preheat your oven to the temperature specified in the recipe, usually around 350°F (175°C). Prepare the mug cake batter according to the recipe instructions. Mix all the ingredients together until well combined. Instead of pouring the batter into a mug, transfer it to a small oven-safe ramekin or a silicone baking mold. Make sure to grease the ramekin or mold beforehand to prevent sticking. Place the filled ramekin or mold onto a baking sheet to catch any potential spills or overflow. Bake the mug cake in the preheated oven for the time indicated in the recipe, typically around 15-20 minutes. Keep a close eye on it and start checking for doneness around the 15-minute mark. The cake is ready when a toothpick inserted into the center comes out clean or with a few moist crumbs. Once baked, carefully remove the ramekin or mold from the oven. Let the cake cool for a few minutes before serving. Remember that baking times may vary depending on the size and material of the ramekin or mold you use, so it's essential to monitor the cake as it bakes. Enjoy your chocolate peanut butter mug cake!
