It’s a simple, foolproof cake that uses everyday ingredients and comes together in one pan, making it both impressive and easy to serve.
Ingredients
- 2 cups (250 g) all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1 cup (2 sticks, 226 g) unsalted butter, softened
- 1 1/2 cups (300 g) granulated sugar
- 3 large eggs, at room temperature
- 1 tablespoon vanilla extract
- 1 cup (240 ml) whole milk, at room temperature
- Green gel food coloring (about 1 teaspoon, or enough to reach a bright Yoshi green)
- For the frosting:
- 1 cup (2 sticks, 226 g) unsalted butter, softened
- 4 cups (480 g) powdered sugar
- 1/4 cup (60 ml) heavy cream
- 2 teaspoons vanilla extract
- Pinch of salt
- For decoration:
- White frosting (for the eyes and belly)
- Black frosting or black gel (for pupils)
- Red frosting or red gel (for the tongue)
- Orange frosting or orange gel (for the shoes)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 13×18-inch (half-sheet) baking pan with butter or non-stick spray, then line it with parchment paper, leaving some overhang on the long sides for easy removal.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In a large bowl, beat the softened butter and sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes. Scrape down the sides as needed.
- Add the eggs one at a time, beating well after each addition. Beat in the vanilla extract.
- With the mixer on low speed, add the dry ingredients in three additions, alternating with the milk, starting and ending with the dry ingredients. Mix just until combined—do not overmix.
- Add the green gel food coloring and mix until the batter is evenly bright green. Add more coloring if needed to achieve the desired shade.
- Pour the batter into the prepared pan and spread it evenly with an offset spatula.
- Bake for 22-25 minutes, or until a toothpick inserted into the center comes out clean. The cake should be lightly golden on top but still green inside.
- Let the cake cool in the pan on a wire rack for 15 minutes, then use the parchment overhang to lift it out and cool completely on the rack.
- While the cake cools, make the frosting: In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, beating on low speed, then add the heavy cream, vanilla, and salt. Increase speed to medium-high and beat for 2-3 minutes until light and fluffy.
- Once the cake is completely cool, spread the white frosting evenly over the top.
- To decorate, use the white frosting to pipe Yoshi’s eyes (two large white circles near the top center), then add black pupils. Pipe a small red oval for the tongue below the eyes, and add orange frosting for the shoes at the bottom corners. Use the remaining frosting to create the white belly area if desired.
- Slice and serve. Store any leftovers in the refrigerator.
Tips
- Gel food coloring is key: Liquid food coloring will make the batter too thin and won’t give you a vibrant green. Gel colors are concentrated and won’t affect the texture.
- Room temperature ingredients: Make sure your butter, eggs, and milk are at room temperature before starting. This helps the batter emulsify properly, resulting in a tender, even crumb.
- Don’t overmix: Once you add the dry ingredients, mix just until the flour streaks disappear. Overmixing develops gluten and can make the cake tough.
- Cool completely before frosting: If the cake is even slightly warm, the frosting will melt and slide off. Patience is key for a clean finish.
Serving Suggestions
Serve this sheet cake as the centerpiece at a Mario or Nintendo-themed party. Cut into squares and pair with a glass of cold milk or a scoop of vanilla ice cream. For extra fun, you can add a few green M&Ms or edible grass sprinkles around the edge of the cake to mimic Yoshi’s world.
Variations
- Chocolate Yoshi: Swap 1/2 cup (60 g) of the flour for unsweetened cocoa powder to make a chocolate version—just add a little extra milk if the batter seems too thick.
- Cupcakes: Divide the batter among lined muffin tins and bake for 18-20 minutes. Decorate each cupcake as a mini Yoshi face.
- Different characters: Use the same vanilla sheet cake base and tint the batter different colors (e.g., red for Mario, blue for Sonic) and change the frosting decorations accordingly.
- Lemon Yoshi: Add 1 tablespoon of lemon zest and replace the vanilla extract with lemon extract for a citrusy twist.
Storage and Reheating
Store the frosted cake in an airtight container in the refrigerator for up to 4 days. The cake actually tastes better the next day as the flavors meld. To serve, let it sit at room temperature for 20-30 minutes to soften. If you prefer a warm slice, microwave a piece for 10-15 seconds, but be aware the frosting will melt slightly.
Frequently Asked Questions
Can I use a different pan size? Yes, you can use a 9×13-inch pan, but the cake will be thicker and will need to bake for 30-35 minutes. Adjust the baking time and check for doneness with a toothpick.
Can I make this cake ahead of time? Absolutely. You can bake the cake a day in advance, wrap it tightly in plastic wrap, and store it at room temperature. Frost and decorate it the next day.
Can I freeze the cake? Yes, you can freeze the unfrosted cake for up to 3 months. Wrap it tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before frosting.
How do I get the green color just right? Start with a small amount of gel food coloring and add more gradually until you reach the desired shade. Remember that the color will deepen slightly as it bakes, so aim for a slightly lighter green than you want in the final cake.
Can I use a store-bought frosting? Yes, you can use store-bought vanilla frosting to save time. Just be aware that it may be sweeter and less stable than homemade buttercream.
Why did my cake sink in the middle? This can happen if the oven door was opened during baking, or if the cake was underbaked. Make sure to preheat the oven fully and avoid opening the door until the minimum baking time has passed.
