Instructions
- Prepare Espresso Milk: Stir espresso powder into room temperature milk until fully dissolved, then set aside to blend flavor for the cake batter.
- Make Cake Batter and Bake: In a large bowl, whisk together cake flour, baking powder, baking soda, and salt. In a separate mixing bowl, beat softened butter and granulated sugar on medium speed for about 2 minutes until pale and light, incorporating air. Add egg whites, sour cream, vanilla extract, and espresso milk mixture, mixing until combined. Gradually add dry ingredients in two batches on low speed, scraping bowl between additions. Fold in mini chocolate chips. Divide batter evenly between prepared pans, smooth tops, and bake at 350°F (175°C) for 25–28 minutes or until toothpick comes out clean. Let cakes cool 15 minutes in pans, then remove and cool completely on racks.
- Prepare Cookie Dough Filling: Beat softened butter, brown sugar, and granulated sugar until smooth. Mix in milk, then flour to form a soft dough. Fold in mini chocolate chips. Cover and chill dough until firm, about 30 minutes.
- Prepare Cheesecake Eyes: Beat cream cheese with granulated sugar until smooth. Add egg yolk and vanilla extract; mix until just combined. Spoon mixture into 1½-inch silicone molds or shape discs on parchment paper. Freeze 30 minutes. Melt white chocolate with corn syrup in microwave in 20-second bursts until smooth. Dip frozen discs into chocolate, letting excess drip off. Place on parchment and chill 15 minutes to set. Use black gel food coloring to pipe off-center pupils onto eyes.
- Bloom Gelatin: Sprinkle gelatin powder over cold water; let sit 5 minutes. Microwave about 10 seconds until liquid.
- Make Cream Cheese Buttercream: Beat softened cream cheese and butter until smooth. Gradually add confectioners’ sugar on low speed until fully incorporated. Add cooled gelatin, heavy cream, vanilla extract, and salt. Beat on high for 3 minutes until fluffy. Reserve ¾ cup of white frosting uncolored if needed.
- Level Cakes: Use a serrated knife to level cake tops for a stable stack and centered filling.
- Assemble Cake with Filling: Place first cake layer cut side up on cake board. Spread chilled cookie dough filling evenly leaving ½-inch border to prevent overflow. Top with second layer, cut side down. Chill 15 minutes to set filling.
- Apply Crumb Coat: Spread a thin layer of white frosting on sides and top of cake to trap crumbs. Chill 20 minutes.
- Color and Pipe Frosting: Tint remaining frosting blue with gel color to desired Sesame Street blue shade. Fit piping bag with grass tip (#233) and pipe short strands of frosting holding bag perpendicular, lifting straight up to create fur texture.
- Decorate Cake: Press cheesecake eyes onto top center of the cake for googly eyes. Arrange chocolate chip cookies around the mouth area for garnish. Refrigerate 30 minutes to set decorations.
- Serve: Remove cake from fridge 30 minutes before serving to reach room temperature. Slice thinly to yield 14–16 servings.
Notes
- Use room temperature ingredients to ensure even mixing and proper texture.
- Level cakes carefully to prevent leaning and ensure even cake layers.
- The cookie dough filling can be made a day ahead and kept chilled.
- Gelatin helps stabilize the frosting for better texture and shape retention.
- Allow the finished cake to come to room temperature before serving for optimal flavor and softness.
- Use gel food coloring for vibrant colors without thinning the frosting.
- Keep the cake refrigerated if not serving immediately to maintain texture and freshness.
