Preheat oven to 350℉/177℃
Beat the butter, olive oil, and brown sugar in a bowl with a standing mixer or large bowl and handheld mixer on low until just incorporated
Add one egg first, beat, and then add the next
Add the vanilla extract and beat until incorporated. Set aside
Sift the tiger nut all-purpose or all-purpose flour with the corn starch into a separate bowl
Add the baking powder, salt, cinnamon, ginger, allspice, nutmeg, and clove
Time to combine but read this first! We are going to alternate between adding the flour mixture and buttermilk a little at a time to the wet ingredients and then mix with a spatula. Do not use the standing mixer or handheld mixer! If you need to make buttermilk, you can add 1 TBSP lemon juice to 1 Cup whole milk and let it sit for 10 minutes.
Add cupcake liners to the cupcake pan
Pour batter into each cupcake mold and bake for 18 minutes. Use a toothpick to insert in the center and remove. If the batter is still runny, bake for two more minutes
Allow the cupcakes to cool, for approximately 10 minutes. While the cupcakes are cooling you can prepare the frosting.
There are a few options to incorporate the cranberry sauce. 1) You can use a paring knife and insert it just off the center of the cupcake. Cutting around in a circle about ¾th deep into the cupcake until the core comes out and you're left with a well in the middle. You can spoon about ½ TBSP of cranberry sauce into that hole. You can pipe buttercream frosting on top. TIP: If you need to create stiffer buttercream peaks, you can add ¼ cup powdered sugar and frosting into a standing mixer bowl and mix until you see it hold more shape (but not too stiff or it will harden a bit). 2) You can spoon about 1/2 of the tub of frosting into a standing mixer. Add ¼ cup of powdered sugar. Mix until just incorporated. From here, you can either spoon this into a piping bag and pipe around the edges of the cupcake and spoon cranberry sauce into the center. Or you can add the cranberry sauce into the standing mixer bowl that has the frosting. You can take a fork and swirl the sauce around until you have a marbled look. Transfer the frosting into a piping bag and pipe swirl onto the cupcakes.
Serve and enjoy!
