Looking for a quick and effortless way to bake a delicious, moist sheet cake? Using your Instant Pot makes it surprisingly simple to achieve bakery-quality results without turning on the oven. Perfect for last-minute gatherings or when oven space is limited, this recipe delivers a fluffy, flavorful cake with minimal fuss.
Ingredients
- 1 1/2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1/2 cup whole milk
- 1 1/2 teaspoons baking powder
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
Instructions
- Prepare your Instant Pot by pouring 1 cup of water into the inner pot. Place a trivet or steamer rack inside and set aside.
- In a mixing bowl, cream together the softened butter and sugar until light and fluffy, about 2-3 minutes.
- Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
- In a separate bowl, whisk together the flour, baking powder, and salt.
- Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined; do not overmix.
- Lightly grease a 7-inch cake pan or springform pan that fits inside your Instant Pot. Pour the batter into the prepared pan, smoothing the top.
- Place the pan on the trivet inside the Instant Pot. Secure the lid and set the valve to sealing.
- Cook on high pressure for 30 minutes. Once done, allow a natural release for 10 minutes, then carefully quick release any remaining pressure.
- Remove the cake from the Instant Pot and let it cool in the pan for about 10 minutes. Transfer to a wire rack to cool completely before frosting or serving.
Tips
- Substitutions: Use dairy-free butter and plant-based milk for a vegan version. You can also add a tablespoon of cocoa powder for a chocolate twist.
- Storage: Keep the cooled cake in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days. Bring to room temperature before serving if refrigerated.
- Common mistakes: Overmixing the batter can make the cake dense. Ensure the water in the Instant Pot is enough to create steam but not so much that it touches the cake pan.
- Pan choice: Use a pan that fits comfortably inside your Instant Pot without touching the sides to promote even cooking.
Serving Suggestions
Serve the cake plain, dusted with powdered sugar, or topped with fresh berries and whipped cream. For a more decadent treat, spread a layer of chocolate ganache or cream cheese frosting on top. It pairs beautifully with a hot cup of coffee or tea for a cozy dessert experience.
Variations
Customize your sheet cake by adding mix-ins like chocolate chips, chopped nuts, or dried fruit into the batter before cooking. For a citrus flavor, stir in lemon or orange zest. You can also make a layered cake by baking two smaller pans and stacking them with frosting in between.
Storage and Reheating
Store the cooled cake in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days. To reheat, place a slice in the microwave for 15-20 seconds until warm. The cake can also be frozen for up to 3 months; wrap tightly in plastic wrap and foil before freezing. Thaw at room temperature or in the refrigerator before serving.
Frequently Asked Questions
Can I use a different size pan?
Yes, but the cooking time may vary. A smaller or larger pan will change the thickness of the cake, which can affect baking time. Use a pan that fits comfortably inside your Instant Pot and adjust cooking time if necessary.
Is it possible to make this cake dairy-free?
Absolutely. Substitute the butter with dairy-free margarine or coconut oil, and use plant-based milk such as almond, soy, or coconut milk. The texture remains moist and delicious.
How do I know when the cake is done?
Insert a toothpick into the center of the cake; if it comes out clean or with just a few moist crumbs, it’s ready. Overcooking can dry out the cake, so start checking around the 30-minute mark.
Can I add frosting directly after baking?
Yes, once the cake has cooled completely, you can frost it. Applying frosting to a warm cake can cause melting and uneven texture, so ensure it’s fully cooled before decorating.
What if my Instant Pot doesn’t have a trivet?
You can use a heatproof metal rack, a silicone steamer basket, or even crumpled aluminum foil to elevate the cake pan above the water level. Just make sure it’s stable and safe for high heat.
How long does it take to cook the cake in the Instant Pot?
The total cook time is approximately 30 minutes under pressure, plus natural release and cooling time. Always check for doneness before removing the cake.
