What defines a sheet cake?

A sheet cake is a single-layer cake baked in a large, flat rectangular pan. Its defining feature is its simplicity, which makes it perfect for serving a crowd. Additionally, unlike layer cakes, it doesn’t require stacking or intricate decoration. As a result, it’s a go-to dessert for casual gatherings or quick baking projects.

What is kefir in baking?

Kefir is a fermented milk product similar to yogurt, but thinner in consistency. In baking, kefir adds a tangy flavor and keeps cakes moist and tender. It also reacts with baking soda to help the batter rise, resulting in a fluffy texture. It’s a great substitute for buttermilk or yogurt in many recipes.

What does a cooked sponge cake look like?

A properly cooked sponge cake should be golden-brown on top and spring back when gently pressed. Moreover, the texture should be light, airy, and slightly spongy. To ensure it’s done, insert a toothpick in the center—it should come out clean, indicating it’s fully baked.
