Easy peanut butter cake

This peanut butter cake is rich, soft and has a buttery taste. The frosting is so delicious I could eat huge spoons full of it without even batting an eyelid. This cake is everything but dry and has a delicious melt-in-your-mouth texture.

When I saw the recipe on Amanda Rettke’s blog, I am Baker I immediately knew that this was the cake I would be baking this week. The moment this cake was in the oven and the beautiful buttery aroma’s started to fill my kitchen I was hooked.

Tips for making peanut butter cake:

Do not overmix the cake batter:

“Mixing until just combined” means that you stop mixing as soon as the white of the flour disappears. When you overmix the batter, elastic gluten strands form that leaves you with a dense, chewy texture. Not exactly the texture we are going for in cakes, hey?

Use ingredients that are at room temperature

Room temperature ingredients come together easily and form a smooth batter that results in evenly baked goods that are airy and light.

Check your cake before time runs out

It is a good idea to check your cake 5 minutes before the recommended time for baking is over. This will prevent overbaking that will leave you with a dry cake.

Many times I have found that my cakes are done before the oven bell rings. Use a baker’s test pin to test or a toothpick. It should come out clean if the cake is done.
