How to Make a Mary Jane Cake: Step-by-Step Guide

Now that you know what makes this cake special, let’s look at how to prepare it at home. Follow these steps for a rich, moist cake that delivers on flavor.

First Step: Preheat the Oven and Prepare Your Pan

Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan or line it with parchment paper to prevent sticking.

Second Step: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, and a pinch of salt. This ensures an even rise and light texture.

Third Step: Cream the Butter, Peanut Butter, and Sugar

In a large bowl, beat the softened butter, peanut butter, and molasses (or brown sugar) until smooth and creamy. This step adds air to the mixture, helping to create a light cake.

Fourth Step: Add the Eggs and Milk

Beat in the eggs one at a time, ensuring each one is fully incorporated before adding the next. Add the milk and vanilla, mixing until well combined.

Fifth Step: Combine Wet and Dry Ingredients

Slowly add the dry ingredients to the wet mixture, stirring just until everything is combined. Be careful not to overmix, as this can make the cake dense.

Sixth Step: Bake the Cake

Pour the batter into your prepared cake pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Seventh Step: Frost the Cake

Once the cake is cool, you can frost it with a peanut butter or cream cheese frosting for added richness. Spread the frosting evenly over the top and enjoy!
