Finding the time to bake multiple different treats for a celebration usually means spending hours measuring out ingredients and washing a mountain of sticky mixing bowls. You can make things significantly easier by mastering one versatile master chocolate batter that can be easily tweaked and baked into various shapes and textures. Relying on an appliance like the Usha OTG gives you the precise temperature control needed to pull off this clever baking trick. By simply adjusting the baking time and the type of pan you use, the dry circulating heat of the oven can transform your standard wet mix into a crackly brownie, a towering sponge, or a gooey molten cake. It is the smartest way to fill your dessert table without spending your entire evening stuck in the kitchen prepping different recipes entirely from scratch.
The Master Chocolate Batter
To create the ultimate master batter, gently melt equal parts of dark chocolate and rich butter together in a saucepan. Once smooth, whisk in a cup of granulated sugar, three whole eggs, and a small cup of plain flour until just combined. This heavy and versatile mixture will serve as the perfect foundation for all five of the desserts below.
Fudgy Chocolate Brownies
Pour the master batter directly into a shallow square tin and bake it at a moderate heat to create a dense and rich traybake. The wide surface area of the pan allows the moisture to evaporate quickly at the surface, creating that classic crackly top while keeping the inside beautifully dense and fudgy. The heating elements in the oven provide consistent top and bottom heat, ensuring the outer edges get perfectly chewy without the centre drying out completely. Cut them into thick squares once they have cooled down slightly and serve them warm with a large scoop of vanilla ice cream.

Molten Lava Cakes
You can take that exact same base mixture and divide it right away into individual ceramic ramekins without altering a single ingredient. Bake them at a much higher temperature for a fraction of the time to change the final texture completely. The intense blast of heat rapidly sets the outer edges of the cake into a firm sponge before the centre has any chance to cook all the way through. When you flip the warm ramekin upside down onto a plate and break the sponge with a spoon, the rich batter inside pours out just like a warm chocolate sauce. It is a brilliant way to make a very simple batter feel like a highly sophisticated restaurant dessert for your guests.

Classic Layered Chocolate Sponge
If you want a traditional celebration cake texture from this dense mix, simply fold a teaspoon of baking powder and a splash of whole milk into your master chocolate batter before dividing it between two round cake tins. Bake them slowly on the middle rack so the ambient heat circulates evenly around the metal tins, allowing the sponge to rise gently without forming a cracked dome in the middle. The steady baking temperature creates a light and airy crumb that is sturdy enough to be stacked high. Once the cakes are completely cool to the touch, you can easily sandwich them together with a thick layer of fresh chocolate ganache or simple buttercream.

Self Saucing Chocolate Pudding
This magical dessert uses your standard base batter with a very clever trick right before it goes into the heat. Pour the thick batter straight into a deep glass baking dish, sprinkle a thick layer of dry cocoa powder and brown sugar over the top, and carefully pour boiling water gently over the entire surface. As it bakes, the oven heat causes the cake batter to rise to the top while the water and sugar mixture sinks to the bottom, creating a rich bubbling chocolate sauce underneath the sponge. It looks like a complete mess going into the oven but comes out as a beautifully comforting pudding.

Crispy Chocolate Cookie Bites
To turn this versatile wet mix into a batch of cookies, you just need to chill the batter in the fridge for about an hour until the melted butter solidifies and makes it firm enough to roll. Drop small rounded balls of the cold dough onto a flat baking tray and bake them quickly on the top rack of your oven. The direct heat from the upper heating element crisps up the outside edges rapidly while the chilled centre stays wonderfully soft and chewy. They take barely ten minutes to bake through completely and are the absolute perfect quick treat to satisfy a sudden sugar craving during the day.
