These homemade sponge cakes feature a delicate, golden exterior and a tender, moist crumb. Each oblong cake is generously filled with a sweet, creamy vanilla filling, offering a delightful contrast in texture and flavor. A light dusting of powdered sugar adds a final touch of sweetness to this classic treat, baked to perfection.
Ensure all cold ingredients, especially butter and eggs, are at room temperature for a smoother batter and filling.
Do not overmix the cake batter; overmixing can lead to a tough cake.
If you do not have a Twinkie pan, you can use a mini loaf pan or even muffin tins, adjusting baking time as needed.
Cool the cakes completely before filling to prevent the filling from melting.
Store homemade Twinkies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
