Step-by-Step Instructions:
1. Prepare Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line with parchment paper for easy removal.
2. Combine Dry Ingredients
In a large bowl, whisk together the flour, granulated sugar, baking soda, and salt. Make sure there are no lumps.
3. Heat Wet Ingredients
In a medium saucepan, combine the water, vegetable oil, and 1/2 cup creamy peanut butter. Bring this mixture to a gentle boil over medium heat, stirring occasionally. Once boiling, remove from heat immediately.
4. Mix Wet and Dry
Carefully pour the hot peanut butter mixture into the dry ingredients. Stir well until just combined.
5. Add Remaining Cake Ingredients
Add the 1/2 cup milk, eggs, and 1 teaspoon vanilla extract to the batter. Mix until smooth, but do not overmix. This is an easy cake recipe, so don’t stress about perfection.
6. Bake the Cake
Pour the batter evenly into your prepared 9×13 inch pan. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
7. Prepare the Frosting
While the cake cools slightly, make the frosting. In a medium bowl, beat the softened butter and 1/2 cup creamy peanut butter together until light and fluffy. Gradually add the powdered sugar, alternating with the 1/4 cup milk and 1 teaspoon vanilla extract. Beat until smooth and creamy.
8. Frost and Serve
Once the cake has cooled completely, spread the peanut butter frosting evenly over the top. Cut into squares and enjoy your delicious easy cake recipe!
Variation Ideas:
- Chocolate Chip Swirl: Swirl 1/2 cup melted chocolate chips into the batter before baking.
- Toasted Nuts: Sprinkle chopped, toasted peanuts on top of the frosting for extra crunch.
- Powdered Sugar Dusting: For a lighter frosting, simply dust the cooled cake with powdered sugar instead of making a full frosting.
