Today's post is part of Humphrey's second birthday bonanza on our partner blog, Dalmatian DIY. Happy birthday, Humphrey! I love playing with clay and during some recent marbling crafts, I thought it would be fun to apply the same techniques to create a marbled cookie (or in this case...a dog treat!). It was surprisingly easy and I love the look. I plan on making these for future human parties as well. You can apply this technique to any smooth rollable neutral-colored cookie/biscuit dough and any combination of colours. The biscuits shown were made using plain/white, red, blue, green, and yellow tinted dough. Since these are dog treats, I used a sour cream and chicken-stock biscuit base, and a combination of food colouring and natural add-ins for each colour in the treats shown, which included some dog-friendly herbs for taste/smell which is why you'll see flecks in my dough/biscuits.
To make your own, you'll need a smooth pale-coloured rollable dough (for haumn treats, a sugar cookie dough would be a good base, and for dogs check out our rollable dog treat dough recipes for ideas), rolling pin, cookie cutters, and standard baking supplies. The confetti bites (love!) were made using mini circle cutter plungers (like these).
- Prepare your cookie/biscuit dough. Separate into smaller bowls for tinting.
- Select your colour(s) and tint each dough individually.
- Unlike small batch polymer clay marbling where I roll and twist canes, a full-sized batch of cookie dough is easier to marble by breaking the dough into pieces and recombining before rolling (as pictured above). An easy way to do this is to separately roll each colour of dough flat. Place loosely into a pile of flat sheets and rip apart into a pile of small-ish pieces. Not too tiny, else your marbling will be muddy when rolled. Gather the pieces together and squeeze into a loose ball.
- Roll and admire your lovely marbled dough. Yeah!
- Cut into shapes as per normal. Since reforming and rolling will muddy the marbling, cut larger shapes first and the smaller-pieces from the gaps and any re-rolled dough. The confetti bites work perfectly.
- Chill (if needed for your dough/shapes) and then bake according to recipe, taking care not to brown your cookies. This may require lowering your temperature or shortening baking time. Cooling in the oven can help make things crisper, if needed.
