Step-by-step preparation of Ridiculously Easy Peanut Butter Texas Sheet Cake
Creating a delicious Ridiculously Easy Peanut Butter Texas Sheet Cake can be a delightful experience. Follow these simple steps to bake a cake that will surely impress friends and family!
Preheat the oven and prepare your baking pan
Begin your cake journey by preheating your oven to 350˚F (175˚C). This ensures your cake bakes evenly and achieves that delightful golden-brown crust. While your oven warms up, grab your trusty 12x18-inch sheet pan. Generously spray it with baking spray, or for a classic touch, rub it with shortening. Sprinkle a tablespoon of flour inside the pan, tilting it gently to coat the surface. This creates a non-stick environment that will make cake removal a breeze once it’s ready!
Melt the butter and combine with other cake ingredients
Next, it's time to melt the butter and combine it with other key ingredients. In a medium-large, microwave-safe bowl, add 1 cup of water, 1 cup of butter (that's 2 sticks), and ½ cup of creamy peanut butter. Microwave this mixture on high for 2 to 2.5 minutes, or until you see that lovely butter melting. After removing it from the microwave, stir in 2 cups of sugar and 1 teaspoon of vanilla extract. Make sure to let it cool for about 5 minutes before proceeding, as it makes it easier to mix in the eggs without scrambling them.
Mixing the cake batter
Once your butter mixture has cooled slightly, it’s time for the fun part: mixing the cake batter! Add 2 large eggs to the bowl and whisk until you achieve a smooth consistency. Then, sprinkle in 1 teaspoon of baking soda and ¼ teaspoon of salt, mixing until well combined. Finally, gently fold in 2 cups of all-purpose flour, whisking vigorously to eliminate any lumps. To finish it off, stir in ½ cup of buttermilk for that added moisture and richness that makes this Peanut Butter Texas Sheet Cake incredibly moist.
Bake the cake to perfection
Pour the beautifully mixed batter into your prepared pan and smooth it out to an even layer. Slide your pan into the preheated oven and bake for about 20-25 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean and the surface springs back when lightly touched. Trust your instincts; every oven is unique, so keep an eye on it!
Prepare and apply the icing
While the cake is baking, it’s icing time! In a medium-large microwave-safe bowl, combine ½ cup of butter, ½ cup of dark brown sugar, and ¼ cup of creamy peanut butter. Microwave for 1 minute, then whisk well. Return it to the microwave for another minute if the butter isn’t fully melted. After that, stir in 4 tablespoons of buttermilk and 1 teaspoon of vanilla extract, mixing until smooth. Gradually add 3½ to 4 cups of powdered sugar, adjusting the thickness of your icing as you deem necessary. A thicker yet pourable consistency is perfect for coating your cake.
Once your cake has cooled for about 20 minutes, cover it with the icing, spreading evenly with a knife. For a fun twist, you can swirl the icing for an eye-catching effect. Serve warm or at room temperature, and watch as everyone falls in love with this Ridiculously Easy Peanut Butter Texas Sheet Cake!
