Chocolate Birthday Cake Butter Mochi Recipes

Steps:

• Make the butter mochi: Heat the oven to 350 degrees. Grease a 9-by-13-inch baking pan with butter.
• In a microwave-safe large bowl, melt the 12 tablespoons butter and chocolate chips by microwaving on high in 30-second increments, stirring and repeating as needed, until just melted.
• Add the granulated sugar to the melted chocolate and stir until combined. Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla and milks.
• In a large bowl, stir together the mochiko, baking powder and cocoa powder until evenly distributed. Fold the liquid chocolate mixture into the dry ingredients, stirring until thoroughly mixed. When the batter is totally smooth, pour it into the prepared baking pan.
• Bake until a toothpick inserted in the center comes out clean, about 1 hour. Let cool slightly.
• As the cake cools, make the frosting: In a bowl with an electric mixer, whip together the peanut butter and Demerara sugar until the mixture has the texture of frosting.
• While the cake is still slightly warm, spread the frosting evenly over the top. Let cool to room temperature. Just before serving, sprinkle with Pop Rocks, if using, and shower sprinkles over the top, then cut into squares and serve.

Steps:

• Make the mochi: Heat the oven to 350 degrees. Lightly butter a 9-by-13-inch cake pan, then line the bottom and sides with parchment paper.
• Whisk the mochiko, baking powder and salt in a medium bowl. Prepare the batter in a stand mixer or in a large bowl with an electric hand mixer or whisk: Whisk the eggs and sugar until pale yellow and thick. Continue whisking while pouring in the coconut milk, then the butter and vanilla. Continue whisking while gradually adding the mochiko mixture. Whisk until the batter is completely smooth. Pour into the prepared pan, then tap it against the counter to get rid of any air bubbles.
• Bake until golden brown and crackly, 1 hour 15 minutes to 1 1/2 hours. When you press the center, it should bounce back but not indent at all. Cool completely in the pan on a wire rack. Use the parchment paper to slide the cooled mochi out of the pan.
• The mochi is delicious plain, but you can add a glaze if you'd like: Mix the confectioners' sugar with 2 tablespoons passion fruit pulp until smooth. It should be thick but drippy. If needed, add another 1 to 2 tablespoons pulp. If you'd like to create an ombré or sunset effect, scrape some into another bowl or multiple bowls and tint with food coloring. Spread the glaze evenly over the mochi, in stripes if you'd like, and let stand until set.
• Cut the mochi into squares or bars. Serve immediately, or keep in an airtight container at room temperature for up to 3 days.

Steps:

• Preheat oven to 350°F. Generously butter a 9"-diameter cake pan or an 8x8" baking pan or 14 cups of two standard 12-cup muffin pans. (If you only have 1 muffin pan, you can bake the extra batter in a small loaf pan or mini muffin pan, or just discard it.) Generously coat pan with sugar, tapping out excess (about ¼ cup should do it).
• Place 1½ cups (300 g) sugar and 6 Tbsp. butter in a large bowl. If using coconut milk, heat in a small saucepan over medium, whisking constantly, until no clumps remain, then whisk into sugar mixture. If using half-and-half, whisk directly into sugar mixture. Add eggs, vanilla, and salt and whisk to combine.
• Whisk rice flour, powdered flavoring of choice (or 3 Tbsp. more rice flour), spice of choice, and baking powder in a medium bowl to combine, then whisk into egg mixture. Scrape batter into prepared pan and sprinkle with coconut or sesame seeds.
• Bake until top begins to crack and cake springs back when gently pressed, 55-65 minutes for cake and 45-55 minutes for cupcakes. Transfer pan to a wire rack and let cake cool in pan 10 minutes. Run a knife around perimeter of cake, place a plate over pan, and invert cake onto plate. Hold wire rack over cake and invert cake onto rack (simply turn cupcakes out onto rack and turn over). Let cool completely.
• Do ahead: Cake can be baked 5 days ahead. Store tightly wrapped at room temperature.
