+
+## Instructions
+
+- Add the following ingredients, ensuring the mixture does not exceed 3/4 of the container's capacity:
+  - Scoop a piece of butter roughly the size of half an egg into the container and microwave on **high for 15 seconds** until melted.
+  - Melt or mash the **chocolate/banana** into **chunks/puree**.
+  - Crack in one egg and whisk to combine.
+  - Add 15g of white (or brown) sugar (add more if you prefer it sweeter) (See Note 4).
+  - Add 1g of salt (**adjust if your subsequent flavor ingredients already contain salt**).
+  - Add 2.5g of baking powder.
+  - Add 15g of flour (the type/grade of flour doesn't matter much).
+  - **Add any flavor ingredients you like!** (Note: dry ingredients like nuts and cookies should not be added at this stage).
+  - Stir until the batter reaches a thick yogurt consistency with no visible dry flour.
+  - Top with optional dry ingredients (excluding instant powders).
+- Give yourself a pat on the back 🥰
+- Microwave on **high for 1 minute** (until the cake becomes fluffy).
+- Carefully remove the cup (**it's hot!**) and share your creation on social media before enjoying.
+
+## Additional Notes
+
+- You can repeat the steps before giving yourself a pat on the back to make a larger cake.
+- Baking powder is used to make the cake fluffy. Most varieties are aluminum-free and cost just a few dollars per pack; keep some on hand.
+- During the step **Add any flavor ingredients you like!**, if you add **liquids** (such as milk), ensure you can still stir the mixture into a **thick yogurt consistency**. Add liquids in small amounts multiple times to prevent the final product from becoming too wet and dense.
+- **Do not fill the container beyond 3/4!!**
