This is actually a genius idea for a club. Can I request a recipe that I made myself? It shouldn't have anything that people would be allergic to, except maybe chocolate chips, but I don't know for sure.
Recipe: Fluffy Microwave Chocolate Cake
Ingredients needed: Butter, chocolate chips, sugar, pancake mix (the powder kind that you mix with liquid), salt, flour (doesnt matter what kind, but white flour is reccomended), milk, and canola oil (you can use another kind if you want, but this is just a recommendation).
Substitutes: If you don't have sugar, try maple syrup. If you don't have pancake mix, use 1 teaspoon of baking powder. If you don't have chocolate chips, use powdered chocolate milk mix or cocoa powder.
Recipe:
Start with a mug or a large bowl (it depends on the amount you want to make). Add butter, chocolate chips (as many as you want), a small dash of salt, and vanilla/chocolate ice cream (optional). Melt in the microwave in 25-30 second intervals until melted, and stir until creamy and thick. Add sugar/maple syrup (add one, or both depending on how sweet you want it. You can also add however much you want) and your preferred cooking oil. Mix well. Then, add 3 tablespoons of flour and 1 tablespoon of pancake mix if making in a mug, and add 4 tablespoons of flour and 2 tablespoons of pancake mix if making in bowl, and stir until combined. Pour milk and stir until creamy and smooth, before putting in microwave. Let it cook in 45 second bursts before checking. Continue the cycle of 45 seconds, and poke with fork to check if its done. If the fork emerges with no cake stuck to it, its done.
Im sorry if this was long, feel free to copy and paste it if you desire. You can credit me if you want, but I don't really care too much. Have fun :)
