This double chocolate sheet cake is inspired by a 100-year-old recipe, and stands the test of time. The secret? Hot coffee enhances the flavor of the chocolate and activates the baking ingredients, creating a light but luscious texture that has everyone going back for seconds. Opt for a weak cup of joe (think diner coffee) to allow the chocolate flavor to shine. Feel free to substitute decaffeinated coffee or even hot water, if desired. Endangered Species Chocolate 75% Oat Milk + Dark Chocolate Chips add a bold, dark chocolate flavor to both the cake and thick, creamy frosting for the ultimate chocolate-on-chocolate bite! Substitute your favorite dairy-free butter substitute to keep this cake dairy-free.

Cake

Method

  • Step 1

    Heat oven to 350F. Coat an 9”x13” rectangular baking dish with nonstick spray. Dust with cocoa. Set aside.

  • Step 2

    In a large bowl, whisk remaining ¼ cup cocoa powder, cake flour, baking powder, baking soda and salt. Set aside.

  • Step 3

    Pour hot coffee over chocolate chips in a medium bowl, stirring to melt. Cool completely.

  • Step 4

    In a stand mixer fitted with a paddle attachment, beat butter and sugar for about 3-4 minutes until light and fluffy, scraping down the sides of the bowl as needed.

  • Step 5

    Meanwhile, add eggs and vanilla extract to cooled coffee mixture, whisking until combined. Add to butter mixture, beating until combined (mixture will not be completely smooth).

  • Step 6

    Add dry ingredients all at once and beat on low speed until no flour remains, being careful not to over mix. Batter will be thin.

  • Step 7

    Pour into prepared baking pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let cool in pan for 20 minutes before unmolding onto a cooling rack. Alternatively, you can serve the cake directly out of the pan. Cool cake completely before frosting.

Frosting

  • Step 1

    Place chocolate chips in a heat-proof bowl over a pot of simmering water, being careful water does not touch the bottom of the bowl. Melt chocolate chips, stirring occasionally. Remove bowl from heat and let cool completely.

  • Step 2

    In a stand mixer fitted with a whisk attachment, add butter and powdered sugar. Beat on medium-high speed until light and fluffy, scraping down the bowl as needed, about 5 minutes.

  • Step 3

    Add cooled chocolate, vanilla extract and salt. Beat on medium-high speed, scraping down the sides of the bowl as needed, until fully incorporated, about 2 minutes.

  • Step 4

    Spread frosting on top of cooled cake, leaving the sides bare if you chose to unmold. Sprinkle with more chocolate chips, if desired, before serving.
