This Easy Fudge Brownie Cake Recipe with Peanut Butter Cookie Dough Frosting is basically the dessert of your dreams. A fudgy brownie cake is topped with a delicious peanut butter frosting that tastes like cookie dough. Plus it is gluten-free and easily made dairy-free!
Line an 8” round cake pan with parchment paper and grease. Set aside.
In a small bowl, stir together sifted cocoa powder, cornstarch and salt. Set aside.
In a microwave safe container or on the stovetop over medium-low heat, melt butter (or coconut oil) and chocolate chips together and stir until smooth.
Add sugar and vanilla to the butter/chocolate mixture and stir to combine.
Add eggs and stir until smooth.
Add dry mixture and stir until smooth and there are no lumps.
Add ½ cup chocolate chips and stir until they’re evenly distributed.
Pour batter into the prepared cake pan.
Bake in the preheated oven for 18-25 minutes, or until the top is set and a toothpick inserted in the center comes out with wet crumbs!
Let cool in the cake pan for about 10 minutes. Then transfer the cake to a wire cooling rack to cool completely.
Make the Peanut Butter Cookie Dough Frosting:
Put old-fashioned oats in the container of your Vitamix or another high powered blender. Put the lid on and blend, starting on low speed and increasing to high, for 30 seconds, or until the oats reach the consistency of flour.
Transfer the oat flour from the Vitamix container into a small bowl. (Alternately, skip these two steps and use an equal amount of oat flour).
Add sea salt and baking soda and stir to combine. Set aside.
In a medium-sized, microwave safe bowl, melt together peanut butter and coconut oil in the microwave or on the stovetop over low heat, stir until smooth.
Add coconut sugar, honey and vanilla and stir to combine.
Add the dry ingredients and stir until the mixture is homogenous (uniform throughout).
Add milk, 1 TBS at a time, until you reach the desired consistency.
Add mini chocolate chips and stir them by hand into the peanut butter cookie dough frosting.
Putting it together:
Once the brownie cake is cooled, transfer to a serving dish and remove parchment paper.
Spread the top evenly with the peanut butter cookie dough frosting.
Sprinkle with chocolate chips or drizzle with melted chocolate if desired for appearances!
Serve and enjoy!
Notes
*if you want to keep this recipe refined sugar free, use unsweetened chocolate instead of chocolate chips. However you may need to increase the coconut sugar. **any granulated sugar works perfectly in this recipe!
