Cake Inspiration

I know I’ve been dangling this cake in front of you for a little while now, but the wait is officially over! Today, I’m sharing my new Oatmeal Biscoff Cake, inspired by the Twisted Sugar cookie, Oatmeal Biscoff.

My friend introduced me to this cookie a few months back and it’s been a favorite ever since. I love the sugar cookie base with the ground oats and chocolate chips in it. And then it’s just topped with a generous serving of Biscoff (cookie butter) spread. It’s simply delicious!

Oatmeal Biscoff Cake

For this cake, I decided to include the Biscoff a little differently than I have with my Biscoff Cake. Instead of using the cookies in my cake layers, I created a giant Biscoff cookie layer that the cake actually bakes on. And similar to the cookie, I used just the Biscoff spread for my filling and then created a Biscoff buttercream.

For the cake layers, I wanted to stay true to the flavor of the cookie, so I didn’t use my oatmeal cake layers from my Oatmeal Chocolate Chip Cookie Cake. Those layers are delicious, but they definitely taste more like an oatmeal cookie than a sugar cookie. So, I opted for a vanilla based and added my ground oats and chocolate chips.

Stacking and Crumb Coat Tutorial

When you make this cake, you’ll bake the cookie crust first and then pour the cake batter right on top of the cookie crust in the cake pan, and then bake again. Allow the layers to cool for about 15 minutes in the pan before inverting them onto cooling racks. Some of the crust will crumble. That’s ok.

TIP: Use a cake lifter to help move the layers around once they’re out of the pan.

Then when you’re ready to stack and decorate your cake, you’ll simply apply the Biscoff spread right on the cake layers (pictured below).

TIP: freezing your crumb coat ensures you don’t get crumbs in your final coat of buttercream.

For your final coat of buttercream, you can place your acrylic disk right on top of the chilled cake. From there, you’ll fill in your sides and smooth them with your straight scraper.

TIP: be sure to freeze your cake again with the disk on so you’re able to cut it off with a knife and get that sharp edge!

Make Ahead Tips

  • Cake layers – The cake layers are a great element to make ahead of time. I like to let me layers cool to room temperature and then wrap them well with plastic wrap. Let the layers thaw for about an hour before you decorate the cake.
  • Buttercream – the buttercream recipe can be made a week ahead of time and stored in airtight containers in the fridge. Make sure to let the buttercream gets back to room temperature and beat it again for a few minutes to restore the fluffy texture.

This cake also stores really well completely finished. Just make sure to put it in a cake box or airtight container. One night in the fridge is ok, otherwise, if you need to store it longer, place it in the freezer.

Instructions

FOR THE COOKIE CRUST

  1. Preheat your oven to 375 degrees F. Spray three 8-inch or four 6-inch round cake pans with non-stick spray and then line with parchment. Spray again. Set aside.

  2. In a medium sized bowl combine the Biscoff cookie crumbs, melted butter and sugar. Stir until all the crumbs are damped by the melted butter. Alternatively, you can add the melted butter and sugar to your food processor after you've pulverized the cookies.

  3. Divide evenly between the three pans or four pans (4oz. in 8" pans and 3 oz. each in the 6' pans) and press down firmly with your hand or the back of a measuring cup.

  4. Bake for 5 to 7 minutes, until golden brown. Let cool while you make the cake batter. 

FOR THE CAKE

  1. Preheat your oven to 325 degrees F.

  2. In a medium sized mixing bowl, whisk together the flour, finely ground oats, cinnamon, baking powder and salt. Set aside.

  3. In the bowl of an electric mixer, fitted with the paddle attachment, cream the butter and the sugar for two minutes on medium-high speed.

  4. Scrape down the sides of the bowl and begin to add the eggs on medium speed, scraping down the sides and bottom of the bowl between addition. Stir in the vanilla.

  5. With the mixer on low speed, add 1/3 of the flour mixture, followed by 1/2 of the milk. Repeat the additions, 1/3 cup flour mixture, 1/2 milk and the final 1/3 cup flour mixture. Only mix until the flour mixture is incorporated, about 30 seconds. Scrape down the sides and bottom of the bowl and mix again for another 20 to 30 seconds on low.

  6. Toss the chocolate chips in one tablespoon flour and then fold the chocolate chips into the cake.

  7. Evenly divide the cake batter between the three 8-inch pans or the four 6-inch pans (20 oz. in each 8" pans and 15 oz. in each 6" pan). Bake the cake layers (either size) at 325 for 28 minutes or until a toothpick inserted in the center of the cake comes out with a few moist crumbs on it.

  8. Let cool for about 15 minutes in the pans before inverting onto a wire rack to cool completely.

  9. Once cooled completely, each layer can be wrapped in plastic wrap and stored in the freezer for up to a week. For longer storing, also wrap in foil.

FOR THE BUTTERCREAM

  1. In the bowl of electric mixer fitted with the paddle attachment, combine the butter and Biscoff spread. Beat on medium-high speed until smooth, about 45 seconds.

  2. Add the powdered sugar to the bowl and mix in, slowly at first until incorporated, then increasing the mixer speed to high. Blend in the vanilla extract, salt and heavy whipping cream, and continue to whip on high speed until very fluffy, about 4-5 minutes, scraping down the sides of the bowl as needed. 

  3. Beat frosting by hand with a wooden spoon to get air bubbles out.

ASSEMBLY

  1. Place the first layer on your cake plate or cake stand (see above tutorial) and cover with about 3/4 cup Biscoff spread.

  2. Place the second layer on top and evenly spread more Biscoff on top.

  3. Place the final cake layer, also top-side up, on the filling and cover the cake with a thin layer of the Biscoff buttercream. This is the crumb coat. Freeze the crumb coated cake for 10 minutes in the freezer.

  4. Continue frosting the cake with the Biscoff buttercream. (Tutorial above)

  1. Totally going to make it! Exactly the kind of dream cake I wanted! Please please do share your oatmeal Biscoff cookies you used for decoration, thanks a lot!

  2. Quick question: in the ingredients it calls for 1 1/2c of milk but in the instructions it says to add 1/2c and then the other 1/2c of milk. I assume it means to just add 1/2 of the milk in each addition? Thanks!

  3. could you use buttermilk instead of milk ? could you use 2 9 inch rounds instead of 3 8inch?
    thanks your cakes look beautiful can’t wait to make this one !!
