Ingredients
- 4 Tbsp all‑purpose flour (or gluten‑free blend)
- 2 Tbsp unsweetened cocoa powder
- 1 Tbsp granulated sugar (or coconut sugar)
- ¼ tsp baking powder
- Pinch of sea salt
- 3 Tbsp milk (dairy or plant‑based)
- 1 Tbsp creamy peanut butter
- 1 Tbsp melted chocolate chips
- ½ tsp vanilla extract
- Optional: a dash of cinnamon or a drizzle of caramel
All the essentials you need, measured for a single mug.
Instructions
- Gather a microwave‑safe mug (minimum 12 oz) and ensure it’s clean and dry.
- In a small bowl, whisk together the flour, cocoa powder, sugar, baking powder, and sea salt until no lumps remain.
- Create a well in the center of the dry mixture and pour in the milk, vanilla extract, and peanut butter.
- Stir vigorously with a fork or small whisk, pulling the dry ingredients from the sides to create a smooth batter. The consistency should be thick but pourable.
- Fold the melted chocolate chips into the batter, reserving a few to sprinkle on top for a decorative finish.
- Transfer the batter into the prepared mug, spreading it evenly. The batter should fill the mug no more than halfway to allow room for rising.
- Microwave on high power (approximately 800‑1000 W) for 60 seconds. Check the center; it should be set but still slightly soft. If needed, continue microwaving in 10‑second bursts to avoid overcooking.
- Remove the mug from the microwave (it will be hot—use a kitchen towel or oven mitt). Let it sit for 30 seconds; the residual heat finishes the cooking process.
- Top with the remaining chocolate chips, a drizzle of melted peanut butter, or a dusting of powdered sugar, if desired.
- Enjoy directly from the mug with a spoon, or gently invert onto a plate for a more elegant presentation.
Pro Tips & Tricks
- Use a microwave‑safe mug with straight sides; tapered mugs can cause the batter to overflow.
- For an extra‑fluffy texture, sift the flour and cocoa powder before mixing.
- If your microwave runs hotter than average, start with 45 seconds and add time gradually.
- For a gooey center, reduce the microwave time by 10‑15 seconds and let the residual heat melt the interior.
- Adding a teaspoon of instant coffee granules intensifies the chocolate flavor without tasting like coffee.
Variations & Substitutions
Vegan: Replace the milk with almond, soy, or oat milk, and use a plant‑based chocolate chip or chopped dark chocolate. Ensure the peanut butter is also free from dairy.
Gluten‑Free: Swap all‑purpose flour for a 1‑to‑1 gluten‑free flour blend. Rice flour works well, but a blend containing xanthan gum will give a better rise.
Nut‑Free: Use sunflower seed butter or soy butter in place of peanut butter. The flavor will shift slightly, but the creamy texture remains.
Extra Crunch: Fold in a tablespoon of chopped peanuts, toasted almonds, or cacao nibs before microwaving for a delightful texture contrast.
Flavor Boosters: Add a pinch of cayenne pepper for a subtle heat, or swirl in a teaspoon of caramel sauce after cooking for a caramel‑peanut swirl.
Storage Tips
While this mug cake is designed to be enjoyed immediately, you can store leftovers in an airtight container in the refrigerator for up to 24 hours. Reheat gently in the microwave for 15‑20 seconds, covering the mug with a damp paper towel to prevent the cake from drying out. For longer storage, the batter (dry ingredients mixed) can be kept in a sealed jar for up to three days; simply add fresh wet ingredients when you’re ready to cook.
